Students have asked these similar questions
Which of the following options best explains how less chlorophyll would affect the proces of
photosynthesis in plants?
6.
A. It would increase the rate of photosynthesis because of the increased production of food.
B. It would limit the amount water plants are able to take in, resulting in a slower rate of
photosynthesis.
C. It would increase the production of oxygen because the plant would need to work hard to
feed themselves.
С.
D. It would limit the amount of light absorbed by the plant and decrease the amount of food
the plant is able to produce for itself.
The ATP and NADPH from the light reactions are used toa. split water.b. cause RuBP carboxylase to fix CO2.c. re-form the photosystems.d. cause electrons to move along their pathways.e. convert 3PG to G3P.
Under certain conditions, the thylakoid membrane of the chloroplast may become 'leaky’ allowing ions to freely diffuse across it. A consequence of that is carbon fixation will stop. Why would the Calvin Cycle stop? A. Because oxidation of water by PSII would stop. B. Because reduction of NADP+ to NADPH would stop. C. Because the stroma would contain ADP but no ATP. D. Because levels of G3P in the stroma would increase.
