Question

Which property of NADP+ should Xavier mention when describing the role of electron carriers in photosynthesis?

a) Its ability to accept and carry high-energy electrons.
b) Its role in producing ATP.
c) Its function in capturing light energy.
d) Its involvement in carbon fixation.

Answer 1

Xavier should mention that NADP+ accepts and carries high-energy electrons, which is a key role of electron carriers in photosynthesis.

Step-by-step explanation:

When describing the role of electron carriers in photosynthesis, Xavier should mention NADP+'s ability to accept and carry high-energy electrons. This compound is very similar to NAD+ in cellular respiration, as it can accept two electrons and a proton to form NADPH, which represents the reduced form of NADP+, and can also lose these elements to revert to NADP+. In photosynthesis, NADP+ receives electrons from carrier molecules that have been excited by chlorophyll molecules. The energy stored in NADPH is subsequently used in the Calvin cycle to help build sugar molecules.
