Textbook Question
Chapter 7, Problem 5TYK
The reactions of the Calvin cycle are not directly dependent on light, but they usually do not occur at night. Why? (Explain your answer.)
a. It is often too cold at night for these reactions to take place.
b. Carbon dioxide concentrations decrease at night.
c. The Calvin cycle depends on products of the light reactions.
d. Plants usually close their stomata at night.

Explain briefly why the following ideas are false.
a. Photosynthesis is the food-making process done by plants.
b The Calvin cycle was called the dark reactions because it can only take place in the absence of light.
c. Photosynthesis can only be powered by sunlight.
If an enzyme in the Calvin cycle were knocked out, then
a
the light-dependent reactions would increase.
b
the light-dependent reactions would stop.
c
the light-dependent reactions would diminish.
d
the light-dependent reactions would be unaffected.
