Question

1. Select all of the true statements about photosynthesis.

a. NADPH is the final electron acceptor

b. During the Calvin cycle, energy stored in the electrons from water is used to build ATP

c. During the light reactions, energy stored in the electrons from water is used to build ATP

d. During the Calvin Cycle, ATP and NADPH are used to make glucose

e. During the light reactions, ATP and NADPH are used to make glucose

f. carbon dioxide and water are the reactants

g. Oxygen is the final electron acceptor

h. glucose and oxygen are the reactants

2. What important role do pigments like chlorophyll a and b play in photosynthesis?

a. They absorb carbon dioxide

b. They absorb light energy

c. They give plants a color

d. They release carbon dioxide

Answer 1

The following are true statements about photosynthesis

a. NADPH is the final electron acceptor

c. During the light reactions, energy stored in the electrons from water is used to build ATP

d. During the Calvin Cycle, ATP and NADPH are used to make glucose

f. carbon dioxide and water are the reactants

Ans-2- Chlorophyll a and b are part of the light-harvesting complex embedded in the membrane of thylakoid and absorb light of 680 and 700 nm.

So option b (They absorb light energy) is correct
