## What happens in the Calvin cycle?

The Calvin cycle is a process that plants and algae use to turn carbon dioxide from the air into sugar the food autotrophs need to grow. … The Calvin cycle has four main steps: carbon fixation reduction phase carbohydrate formation and regeneration phase.

## How many molecules of glucose are produced by each cycle of the light reaction?

The Chemical Reaction

The overall chemical reaction for photosynthesis is 6 molecules of carbon dioxide (CO2) and 6 molecules of water (H2O) with the addition of solar energy. This produces 1 molecule of glucose (C6H12O6) and 6 molecules of oxygen (O2).

## How many CO2 molecules are in one turn of the Calvin cycle?

a. How many CO molecules are used in one turn of the Calvin cycle? Three CO molecules are used each time.

## What is the end product of Calvin cycle?

The reactions of the Calvin cycle add carbon (from carbon dioxide in the atmosphere) to a simple five-carbon molecule called RuBP. These reactions use chemical energy from NADPH and ATP that were produced in the light reactions. The final product of the Calvin cycle is glucose.

## How many ATP molecules are required for every CO2 molecule entering Calvin cycle?

3 molecules

Hence for every CO2 molecule entering the Calvin cycle 3 molecules of ATP and 2 of NADPH are required.

## What happens during the Calvin cycle How does the Calvin cycle depend on the light reactions?

How does the Calvin cycle depend on the Light reactions? –The ATP provides the energy and the NADPH supplies the electrons for the Calvin cycle which converts carbon dioxide to sugar. The ADP and NADP+ that result from the Calvin cycle shuttle back to the light reactions which regenerate ATP and NADPH.

## What is required for the Calvin cycle?

The Calvin Cycle

All three necessary conditions are required – chlorophyll pigments the chloroplast “theater ” and enzyme catalysts. The first stage transforms light energy into chemical energy stored to this point in molecules of ATP and NADPH.

## Which of the following is are required in the Calvin cycle?

The Calvin cycle is a series of light-independent reactions which means that that the correct answer is C. light. The Calvin cycle depends on the light-dependant reactions of photosynthesis to operate but does not itself require light.

## How many molecules are formed from the cleavage of glucose during the first step of glycolysis how many carbons are found in the resulting molecules?

Glycolysis starts with glucose and ends with two pyruvate molecules a total of four ATP molecules and two molecules of NADH. Two ATP molecules were used in the first half of the pathway to prepare the six-carbon ring for cleavage so the cell has a net gain of two ATP molecules and two NADH molecules for its use.

## What is the glucose molecule?

Glucose is a simple sugar with the molecular formula C6H12O6. … Glucose is a monosaccharide containing six carbon atoms and an aldehyde group and is therefore an aldohexose. The glucose molecule can exist in an open-chain (acyclic) as well as ring (cyclic) form.

## Which molecules are produced during the Calvin cycle?

The Calvin cycle is the term used for the reactions of photosynthesis that use the energy stored by the light-dependent reactions to form glucose and other carbohydrate molecules.

## What is the primary product of Calvin cycle?

The primary product of the Calvin cycle is glyceraldehyde three phosphate or G3P.

## How does the Calvin cycle produce high energy sugars?

carbon dioxide molecules

The Calvin cycle uses carbon dioxide molecules as well as ATP and NADPH from the light-dependent reactions to make sugars. The reactions of the Calvin cycle use ATP and NADPH as energy sources. They do not directly require light.

## Why does it take three turns of the Calvin cycle to produce G3P the initial product of photosynthesis?

Why does it take three turns of the Calvin cycle to produce G3P the initial product of photosynthesis? Because G3P has three carbon atoms and each turn of the cycle takes in one carbon atom in the form of carbon dioxide.

## What is the net reaction of the Calvin cycle?

The net reaction of the Calvin cycle is the conversion of CO2 into the three-carbon sugar G3P. Along the way reactions rearrange carbon atoms among intermediate compounds and use the ATP and NADPH produced by the light reactions.

## Does the Calvin cycle produce oxygen?

The Calvin Cycle converts three water and three carbon dioxide molecules into one molecule of glyceraldehyde. The six left over oxygen atoms are released into the atmosphere where they are available for use in respiration.

## How many turns of the Calvin cycle are needed to produce one glucose molecule explain your answer?

Three turns of the Calvin cycle are needed to make one G3P molecule that can exit the cycle and go towards making glucose.

## How many ATP does light dependent reaction produce?

The light-dependent reactions can be summarized as follows: 12 H2O + 12 NADP+ + 18 ADP + 18 Pi + light and chlorophyll yields 6 O2 + 12 NADPH + 18 ATP.

## How many ATP are produced in photosynthesis?

Glucose combines with oxygen (oxidation) forming carbon dioxide water and 38 molecules of ATP.

## How many ATP are produced in glycolysis?

2 ATP

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).
