question 1
while the energy absorbed by one type of chlorophyll molecule is used to form molecules of atp, electrons from a second kind of chlorophyll molecule are used
a. in the mitochondria
b. to make h₂o
c. to make co₂
d. to migrate to another proton pump
e. in forming molecules of nadph

Explanation:

In photosynthesis, when one type of chlorophyll molecule absorbs energy to form ATP, electrons from another type of chlorophyll molecule are used in the formation of NADPH. Mitochondria are involved in cellular respiration (not directly in this chlorophyll - related photosynthetic electron - transfer step for the given context). Water (\(H_2O\)) is split (not made) in the light - dependent reactions of photosynthesis to provide electrons. Carbon dioxide (\(CO_2\)) is fixed in the Calvin cycle (a different part of photosynthesis not directly related to this electron - transfer for the formation of the molecule in question here). Proton pumps are involved in the proton gradient for ATP synthesis, but the key molecule formed from the electron transfer of the second - type chlorophyll is NADPH.

Answer:

e. in forming molecules of NADPH
