Outline the three phases of the Calvin cycle.
The Calvin cycle requires both ATP and NADPH. Which of these molecules provides the major input of energy needed to synthesize carbohydrates?
There are some similarities and some differences between the citric acid cycle in the mitochondrion and the Calvin cycle in photosynthesis. Which of the following is NOT a true difference between the two cycles?
Both involve CO2, but in the Calvin cycle CO2 is used brought into the process as a source of carbon for the sugar being built. In the Mitochondrion, CO2 is removed from the sugar and leaves the cell.
In the Calvin cycle, ATP is used to carry chemical energy from the light reactions to the the Calvin cycle where the chemical energy is incorporated in the sugar molecule that is being manufactured. In the mitochondrion, ATP is produced and brought out of the mitochondrion so it can provide chemical energy to the many activities going on in the cytoplasm
The first step in the Calvin cycle, the carboxylation of RuBP, produces a 12-carbon product that splits into two 6 carbon pieces. In the first step of the citric acid…

- Which among the following statements is INCORRECT? The first event in the Calvin cycle is the attachment of carbon dioxide to the five-carbon RuBP molecule, which forms a six-carbon molecule that breaks down into two 3PG molecules. The first event in the Calvin cycle is the attachment of carbon dioxide to the five-carbon RuBP molecule, which is a reaction assisted by large quantities of RuBP carboxylase enzyme. The first event in the Calvin cycle is the attachment of carbon dioxide to the five-carbon RuBP molecule, which decreases cell carbon dioxide levels, which increases the diffusion gradient. The first event in the Calvin cycle is the attachment of carbon dioxide to the five-carbon RuBP molecule, which immediately becomes a six-carbon sugar that is the base for starch, sucrose, cellulose, etc.arrow_forwardName the process of conversion of ADP into ATP during the first phase of photosynthesis.arrow_forwardDescribe the three steps of the Calvin cycle and whenATP and/or NADPH is needed.arrow_forward
