What Is The Purpose Of The Folded Inner Membrane In Mitochondria

What Is The Purpose Of The Folded Inner Membrane In Mitochondria?

To increase the capacity of the mitochondrion to synthesize ATP the inner membrane is folded to form cristae. These folds allow a much greater amount of electron transport chain enzymes and ATP synthase to be packed into the mitochondrion.

What is the purpose of the folded inner membrane in mitochondria quizlet?

Explain- The inner membrane of mitochondria is folded to create a larger surface area which allows more space for enzyme attachment during respiration.

What is the purpose of the folded membrane?

The folding of the inner membrane increases the surface area inside the organelle. Since many of the chemical reactions happen on the inner membrane the increased surface area creates more space for reactions to occur.

What is the folded membrane inside the mitochondria?

Each mitochondrion has two membranes: an inner membrane which is highly convoluted and folded into finger-like projections called cristae and a smooth outer membrane that is a selective barrier to molecules from the cytoplasm.

How do the inner folds of the mitochondria assist with their function quizlet?

The cristae (folded membrane) greatly increases the surface area of the inner membrane to allow a higher transport rate of reactants (eg H+ and O2) and products (eg Co2 and H20) and also allows compartmentalization so the reactions can occur in optimum conditions.

What happens across the inner membrane of the mitochondria?

At the inner mitochondrial membrane a high energy electron is passed along an electron transport chain. The energy released pumps hydrogen out of the matrix space. The gradient created by this drives hydrogen back through the membrane through ATP synthase.

Why is it important that the inner membrane of the mitochondria be folded in both plant and animal cells?

Why is it important that the inner membrane of the mitochondria be folded in both plant and animal cells? The folded membrane increases the structure strength of the mitochondria. The folded membrane increases the surface area for energy production.

Why are the inner membranes of chloroplasts and mitochondria highly folded?

Mitochondria have their own DNA and a double membrane like the nucleus and chloroplast. The outer membrane is smooth while the inner membrane is convoluted into folds called cristae in order to increase the surface area.

Why is the inner membrane of mitochondria ruffled?

Why is the inner membrane of mitochondria ruffled? *The inner layer of mitochondria is ruffled because of more surface area. … *Mitochondria might have originated from symbiotic bacteria because they took up residence inside the first eukaryotic cells. Desribe the arrangment of mocrotubles that compose the centrioles.

What is the main purpose of the mitochondria quizlet?

powerhouses of the cell. creates energy for the cell.

What is the main function of the mitochondria quizlet?

What is the primary function of the mitochondria? They are the main sites of ATP production.

What is the function of the mitochondria in the cell quizlet?

Mitochondria are known as the powerhouses of the cell. They are organelles that act like a digestive system which takes in nutrients breaks them down and creates energy rich molecules for the cell. Many of the reactions involved in cellular respiration happen in the mitochondria.

What does the inner membrane of mitochondria contain?

The inner mitochondrial membrane contains many copies of a protein called the F0F1ATPase. This is also called ATP synthase. It consists of two parts: the F component spans the membrane and provides a channel for protons to move into the matrix from the intermembrane space.

What happens across the inner membrane of the mitochondria quizlet?

Inside the inner membrane of the mitochondria there is a chain of electron carriers known as the electron transport chain. … These 2 electrons pass along the chain and release energy from 1 carrier to the next. At 3 locations along the chain enough energy is released to produce ATP via ATP synthase.

How is the inner membrane of the mitochondria unique?

The inner membrane is freely permeable to oxygen carbon dioxide and water only. It is much less permeable to ions and small molecules than the outer membrane creating compartments by separating the matrix from the cytosolic environment. This compartmentalization is a necessary feature for metabolism.

Which of the following best explains how the extensive folding of the inner mitochondrial membrane benefits a eukaryotic cell?

Which of the following best explains how the extensive folding of the inner mitochondrial membrane benefits a eukaryotic cell? It provides better insulation for reactions in the matrix from conditions outside the mitochondria.

What would happen if the inner mitochondrial membrane is freely permeable to hydrogen ions?

If protons (H+) were able to freely move across the mitochondrial membrane cellular respiration will not occur.

What is the main function of the mitochondria within the cells?

​Mitochondria. Mitochondria are membrane-bound cell organelles (mitochondrion singular) that generate most of the chemical energy needed to power the cell’s biochemical reactions. Chemical energy produced by the mitochondria is stored in a small molecule called adenosine triphosphate (ATP).

What is the function of inner membrane in chloroplast?

Like mitochondria chloroplasts are surrounded by an inner and an outer membrane. The inner membrane encloses a fluid-filled region called the stroma that contains enzymes for the light-independent reactions of photosynthesis.

Is inner membrane of chloroplast folded?

Like mitochondria chloroplasts are surrounded by two membranes. … Chloroplasts also have a third internal membrane called the thylakoid membrane which is extensively folded and appears as stacks of flattened disks in electron micrographs.

How is the structure of the inner mitochondrial membrane related to its function in oxidative phosphorylation?

The inner mitochondrial membrane is the site of oxidative phosphorylation and contains the electron transport chain. It is folded into cristae creating a large surface area for oxidative phosphorylation to occur increasing the rate of reaction.

Why is the double membrane of the mitochondria important?

The mitochondrion has a primary role in energy metabolism a role that is intimately connected with its double-membrane structure (outer and inner each comprising a lipid bilayer). Formation of mitochondria (mitochondrial biogenesis) is under the dual control of the nuclear and mitochondrial genetic systems.

What major function occurs on the specific membranes indicated by a?

What major function occurs on the specific membranes indicated by A? Structure A is the rough endoplasmic reticulum (ER). The figure illustrates how proteins are synthesized on ribosomes bound to the rough ER sorted in the Golgi and delivered to the plasma membrane for secretion or packaged into lysosomes.

What is the role of the inner mitochondrial membrane in establishing an electrochemical gradient?

The electrochemical proton gradient across the inner mitochondrial membrane is used to drive ATP synthesis in the critical process of oxidative phosphorylation (Figure 14-14). This is made possible by the membrane-bound enzyme ATP synthase mentioned previously.

What process occurs in the inner membrane?

The correct answer: The process which occurs within the inner mitochondrial membrane c) Electron Transport Chain.

What ion is responsible for the membrane potential formed across the inner mitochondrial membrane?

The mitochondrial membrane potential (ΔΨm) generated by proton pumps (Complexes I III and IV) is an essential component in the process of energy storage during oxidative phosphorylation. Together with the proton gradient (ΔpH) ΔΨm forms the transmembrane potential of hydrogen ions which is harnessed to make ATP.

What happens inside of mitochondria?

Mitochondria using oxygen available within the cell convert chemical energy from food in the cell to energy in a form usable to the host cell. The process is called oxidative phosphorylation and it happens inside mitochondria. … In ATP the energy is stored in the form of chemical bonds.

Which of the following best explains how the phospholipid bilayer of a transport vesicle?

Which of the following best explains how the phospholipid bilayer of a transport vesicle contributes to cellular functions? The phospholipid bilayer allows the vesicle to fuse with the Golgi apparatus and the plasma membrane allowing the exocytosis of proteins.

How does a mitochondrion facilitate the movement of some materials between cells?

How does a mitochondrion facilitate the movement of some materials between cells? It supplies the energy needed for moving molecules through membranes. (Mitochondria convert glucose to ATP the primary molecule of energy transfer for cells.)

Which best explains why the nucleus is important to cell?

Explanation: Nucleus is highly important for all the cells. It is often called ‘Brain of cell’ as it Regulates the cell activities. It contains the genetic material ( DNA OR RNA ) which is passed on to the next generations etc.

What would be the impact of the inner mitochondrial membrane was freely permeable to protons?

If the inner mitochondrial membrane was freely permeable to protons (H+) what would be the most devastating result to the cell? ATP would not be produced by oxidative phosphorylation.

What molecules on the inner mitochondrial membrane are responsible for its permeability to hydrogen?

Similarly hydrogen ions in the matrix space can only pass through the inner mitochondrial membrane through a membrane protein called ATP synthase. This protein acts as a tiny generator turned by the force of the hydrogen ions diffusing through it down their electrochemical gradient.

Is the inner mitochondrial membrane permeable to H+?

The inner membrane is impermeable to H+ but the outer membrane of the mitochondria will allow H+ to pass through. Thus placing mitochondria in a low pH buffer produces a H+ gradient that can generate ATP through ATP synthetase.

How do mitochondria move around the cell?

Mitochondria primarily move by the action of molecular motors along cytoskeletal elements (Figure 2 and Table 1). Like other organelles mitochondria associate with specific motor isoforms through organelle-specific adaptors and their movement is sensitive to disruption of these motors and adaptor proteins.
