Question

Calvin cycle produces more of what than the plant needs and what happens?

a) Oxygen; it accumulates in the plant
b) ATP; it converts to ADP
c) NADPH; it converts to NADP+
d) Carbohydrates; it becomes stored or used for growth

Answer 1

The Calvin cycle produces carbohydrates, which the plant uses for energy, growth, and storage. Excess carbohydrates are stored as starch or used for structural growth.

Step-by-step explanation:

The Calvin cycle, a critical component of photosynthesis, produces carbohydrates such as glucose. Carbohydrates are used by the plant for energy and growth, and when there's excess, they become stored as starch or other complex carbohydrates, or they are used for structural growth in the plant. This process enables plants to create more food than they immediately need, allowing them to grow and store energy for future use.

The Calvin cycle harnesses energy in the form of ATP and NADPH, with 6 molecules of ATP and 6 molecules of NADPH utilized to produce Glyceraldehyde-3-phosphate (GA3P) molecules. These energy-storing GA3P molecules are then used to generate more complex carbohydrates like glucose, which remains in the plant for either immediate use or storage.
