Imagine that a researcher has developed a way to isolate thylakoids from chloroplasts and to make the pH of the thylakoid space acidic.If these isolated thylakoids are transferred to a pH8 solution in the dark,what might the researcher expect to observe? A)that the isolated thylakoids produce ATP B)that the isolated thylakoids produce glucose C)that the isolated thylakoids reduce NADP⁺ to NADPH D)that the isolated thylakoids produce oxygen gas

Question

Quizplus · Accepted Answer

When isolated thylakoids are transferred from an acidic environment to a basic one (pH 8), a proton gradient across the thylakoid membrane is created. This gradient drives ATP synthesis through chemiosmosis, even in the absence of light, as long as the gradient is maintained. This process does not directly involve the production of glucose, reduction of NADP+ to NADPH, or the production of oxygen gas, which are all processes that require light and are part of the light-dependent and light-independent reactions of photosynthesis.
