Question

71. Choose the false statement:

A. According to the most widely accepted model for the two chemiosmotic gradients we studied, the mitochondrial matrix space is equivalent to the thylakoid space of chloroplasts.

B. Cyclic and non-cyclic photophosphorylation share many of the same components; both must be active in order to generate enough ATP to drive carbon fixation in the Calvin cycle.

C. When light activates pigments in photosystem II, electrons originally split from water are energized, bound by a primary electron acceptor and eventually, after passing through photosystem I, are picked up by NADP⁺.

Answer 1

71.Answer

The false statement is:. Choose the false statement:

A. According to the most widely accepted model for the two chemiosmotic gradients we studied, the mitochondrial matrix space is equivalent to the thylakoid space of chloroplasts.

Because mitochondrial inner membrane is compared to thylakoid space as they both are involved in electron transportation.

Other statements are true:

B. Both of the cyclic and noncyclic photophosphorylation are important to generate ATP for Calvin cycle and both work simultaneously also they have the similar components involved in electron transport and ATP generation

C.When light activates pigments in photosystem II, electrons originally split from water are energized, bound by a primary electron acceptor and eventually, after passing through photosystem I, are picked up by NADP+ and this is the order followed in ATP generation.
