What energy source creates the most ATP?

Explanation: The electron transport chain generates the most ATP out of all three major phases of cellular respiration. Glycolysis produces a net of 2 ATP per molecule of glucose. In the Krebs cycle there is one GTP (which is an ATP equivalent) generate in the conversion of succinyl-CoA to succinate.

Which process generates the greatest amount of energy?

The process of aerobic respiration produces a massive amount of energy. This process tends to produce approximately 38 ATP molecules.

Which pathway produces the most energy from a glucose molecule?

So oxidative phosphorylation is the metabolic cycle that produces the most net ATP per glucose molecule.

How does glucose hold energy?

It comes from the glucose in foods that you eat! Energy is stored in the chemical bonds of the glucose molecules. Once glucose is digested and transported to your cells a process called cellular respiration releases the stored energy and converts it to energy that your cells can use.

How does glucose turn into energy?

Cells convert glucose to ATP in a process called cellular respiration. Cellular respiration: process of turning glucose into energy In the form of ATP. … Each 6 carbon molecule of glucose is converted to two 3 carbon molecules of pyruvic acid in the process of glycolysis.

How is glucose converted to ATP?

Glucose is converted into ATP by cellular respiration. Glucose is completely oxidised to CO2 and water producing energy which is stored as ATP. One molecule of glucose produces 38 ATP molecules by aerobic respiration. Aerobic respiration occurs in the cytoplasm and mitochondria.

Which of the following processes produces the most ATP per molecule of glucose?

Aerobic respiration

Answer: A) Aerobic respiration produces the most ATP per molecule of glucose.

Why is ATP a better energy source than glucose?

It is much more energy efficient to add and remove those phosphate groups than to add and subtract elements from a glucose molecule as there is no way to effectively break it down without significantly changing its structure which makes it harder to build back up.

Why is ATP the most common energy source?

ATP is the main source of energy for most cellular processes. … Because of the presence of unstable high-energy bonds in ATP it is readily hydrolyzed in reactions to release a large amount of energy.

Which process produces the most ATP quizlet?

Most of the ATP in cellular respiration is produced by the process of chemiosmosis.

Which process produces the most ATP aerobic or anaerobic?

Summary
  • Aerobic respiration produces much more ATP than anaerobic respiration.
  • Anaerobic respiration occurs more quickly than aerobic respiration.

Where is the most ATP produced in cellular respiration?

mitochondria

The stage that produces most of the ATP during cellular respiration is the electron transport system (ETS) present in mitochondria.

Which process creates the most ATP per glucose molecule metabolized quizlet?

Most of the ATP in cellular respiration is produced by the process of chemiosmosis.

Which metabolic pathway is the most energy efficient?

Aerobic metabolism is up to 15 times more efficient than anaerobic metabolism which yields two molecules ATP per one molecule glucose. Both types of metabolism share the initial pathway of glycolysis but aerobic metabolism continues with the Krebs cycle and oxidative phosphorylation.

What happens to glucose during glycolysis?

During glycolysis glucose ultimately breaks down into pyruvate and energy a total of 2 ATP is derived in the process (Glucose + 2 NAD+ + 2 ADP + 2 Pi –> 2 Pyruvate + 2 NADH + 2 H+ + 2 ATP + 2 H2O). … The specific form of glucose used in glycolysis is glucose 6-phosphate.

Does glucose produce ATP?

In total the complete oxidation of a molecule of glucose to H2O and CO2 is used by the cell to produce about 30 molecules of ATP. In contrast only 2 molecules of ATP are produced per molecule of glucose by glycolysis alone.

Does glucose have more energy than ATP?

Given that the oxidation of for example glucose ( C6H12O6 ) by cellular respiration can produce 38 ATP it would follow that there is more energy in a molecule of sugar than a molecule of ATP.

What is glucose and ATP?

Glucose is the carbohydrate produced by photosynthesis. Energy-rich glucose is delivered through your blood to each of your cells. ATP is the usable form of energy for your cells.

Why is glucose the primary energy source for cells?

Glucose is the most important substrate of cell metabolism. It is the carbohydrate fulfilling the task of being the energy transport system of the body. Several parts of the body like the nervous system or blood cells are completely dependent on glucose as the supplier of energy.

How does ATP provide energy?

ATP is able to power cellular processes by transferring a phosphate group to another molecule (a process called phosphorylation). This transfer is carried out by special enzymes that couple the release of energy from ATP to cellular activities that require energy.

How is ATP converted into energy?

Turning ATP Into Energy

Whenever a cell needs energy it breaks the beta-gamma phosphate bond to create adenosine diphosphate (ADP) and a free phosphate molecule. … Cells get energy in the form of ATP through a process called respiration a series of chemical reactions oxidizing six-carbon glucose to form carbon dioxide.

How is the energy of a glucose molecule harvested by a cell?

In aerobic respiration the cell harvests energy from glucose molecules in a sequence of four major pathways: glycolysis pyruvate oxidation the Krebs cycle and the electron transport chain. Oxygen is the final electron acceptor. Anaerobic respiration donates the harvested electrons to other inorganic compounds.

How many ATP does glucose produce?

In a eukaryotic cell the process of cellular respiration can metabolize one molecule of glucose into 30 to 32 ATP. The process of glycolysis only produces two ATP while all the rest are produced during the electron transport chain.

Which process produces the greatest number of ATP molecules?

The stage of aerobic respiration that produces the greatest number of ATP molecules is the electron transport chain.

Which of the following processes produces the maximum yield in ATP when one molecule of glucose is completely oxidized?

The theoretical maximum yield of ATP for the oxidation of one molecule of glucose during aerobic respiration is 38. In terms of substrate-level phosphorylation oxidative phosphorylation and the component pathways involved briefly explain how this number is obtained.

Does ATP release a large amount of energy?

As noted below energy is released by the hydrolysis of ATP. … It is the formation of new bonds and lower-energy inorganic phosphate with a release of a larger amount of energy that lowers the total energy of the system and makes it more stable.

Is ATP the most efficient energy source?

Nonetheless ATP is the most efficient energy source used in cellular metabolism. The reasons that ATP is more reliable than the other nucleoside triphosphate in producing energy are: … Thus ATP has a high phosphoryl-transfer potential (tendency to release phosphate to become ADP is high).

How is ATP used it is used as?

It is often referred to as the energy currency of the cell and can be compared to storing money in a bank. ATP can be used to store energy for future reactions or be withdrawn to pay for reactions when energy is required by the cell. Animals store the energy obtained from the breakdown of food as ATP.

Which process produces the most ATP and what other compound is produced in that process?

Answer and Explanation: The electron transport chain of the cellular respiration process produces maximum ATP.

Which of the following is the source of the energy that is used to produce the Chemiosmotic gradient in mitochondria?

The chemiosmotic theory

The theory suggests essentially that most adenosine triphosphate (ATP) synthesis in respiring cells comes from the electrochemical gradient across the inner membranes of mitochondria by using the energy of NADH and FADH2 formed from the breaking down of energy-rich molecules such as glucose.

How much ATP is produced in anaerobic glycolysis?

Anaerobic glycolysis yields two ATP molecules for each glucose molecule metabolized…oxidation of glucose in the mitochondrion would yield an additional 34 ATP molecules.
