Question

One of the major claims being made surrounding ""b"" (photosystem ii of the light reaction) is that solar energy is required for the reduction of NADP to NADPH. How could you test this idea?

a) Deactivate Photosystem II and observe if NADP can still be reduced.

b) Increase the concentration of NADP and check for changes in Photosystem II activity.

c) Provide an alternative light source and monitor NADP reduction.

d) Remove all pigments from Photosystem II and assess the impact on NADP reduction.

Answer 1

To test the idea that solar energy is required for the reduction of NADP to NADPH in Photosystem II, experiments can be conducted by deactivating Photosystem II, increasing the concentration of NADP, providing an alternative light source, or removing all pigments from Photosystem II.

Step-by-step explanation:

To test the idea that solar energy is required for the reduction of NADP to NADPH in Photosystem II, several experiments can be conducted:

1. Deactivate Photosystem II: By deactivating Photosystem II and observing if NADP can still be reduced, we can determine if Photosystem II is necessary for the reduction of NADP to NADPH.
2. Increase the concentration of NADP: By increasing the concentration of NADP and checking for changes in Photosystem II activity, we can investigate if NADP concentration affects the reduction of NADP to NADPH.
3. Provide an alternative light source: By providing an alternative light source and monitoring NADP reduction, we can determine if solar energy is specifically required for the reduction of NADP to NADPH.
4. Remove all pigments from Photosystem II: By removing all pigments from Photosystem II and assessing the impact on NADP reduction, we can determine if the pigments in Photosystem II are necessary for the reduction of NADP to NADPH.
