Question

Plastoquinone is to ubiquinone as the thylakoid membrane is to:

stromal membranes.
b. the outer mitochondrial membrane.
c. the inner mitochondrial membrane.
d. the plasma membrane.
e. the inner chloroplast membrane.

Answer 1

The thylakoid membrane is to the inner chloroplast membrane as plastocyanine is to plastoquinone. The thylakoid membrane contains components of the light dependent reactions, while the inner chloroplast membrane contains the chemicals needed for the Calvin cycle and components of the light dependent reactions.

Step-by-step explanation:

The thylakoid membrane is to the inner chloroplast membrane as plastocyanine is to plastoquinone. Just as plastocyanine and plastoquinone perform redox reactions in the electron transport chain, the thylakoid membrane contains components of the light dependent reactions, including photosystems I and II, as well as the enzyme NAD+ reductase. The inner chloroplast membrane contains the chemicals needed for the Calvin cycle and components of the light dependent reactions.
