Question

Some plants are able to photosynthesize on hot and dry days without losing too much water in their leaves, there are two main strategies to do this. in C4 plants carbon fixation happens in one cell type whereas the light reactions occur in a different cell type. In CAM plants, the light reactions happen during the day while the Calvin cycle happens at night. Which of the following statements must be FALSE regarding C4 and CAM plant metabolism? Note: more than one answer is possible, check all appropriate choices Select all that apply: a. Leaves open their stomata (openings at base of leaf) to allow oxygen and carbon dioxide exchange which all allows water loss cross out cross out b. The dark reactions do not require light to proceed C. ATP and NADPH are able to be 'saved' for the appropriate time or place for the Calvin cycle cross out d. ATP produced by the light reactions drives other processes in the plant when the Calvin cycle is not occuring e. Water loss is a problem for the plant because it loses an electron donor cross out cross out

Explanation / Answer

Ans is d) ATP produced by light reactions drives other processes in the plants when the Calvin cycle is not occuring.

The ATP and NADPH are two important elements that are required during the light reactions and are used during the Calvin Cycle and this helps in reduction of carbon dioxide to sugar.
