BIOLOGY Plants problems

Multiple choice questions:

1. NADPH levels will go up.

2. NADPH levels will go down.

3. Photosystem I and II will be uncoupled.

4. ATP production will cease.

You are looking at two species of plants that are growing under identical conditions. The voltage potential between the inner thylakoid and chloroplast stroma is lesser in species “A” compared to species “B”. You conclude

1. The electron transport chain after photosystem I is more efficient in B.

2. The electron transport chain after photosystem II is more efficient in B

3. The electron transport chain after photosystem I is more efficient in A.

4. The electron transport chain after photosystem II is more efficient in A.
