7.

Hannah, Kai, and Mia are studying photosynthesis for their biology project. They are particularly interested in the Calvin cycle. Can you help them understand the role of ATP and NADPH in the Calvin cycle?

a)

ATP and NADPH are used for breaking down glucose in the Calvin cycle

b)

ATP and NADPH provide the energy and reducing power needed for the synthesis of glucose in the Calvin cycle.

c)

ATP and NADPH are not involved in the Calvin cycle

d)

ATP and NADPH are only used for storing energy in the Calvin cycle

8.

Samuel, Noah, and Harper are conducting a science experiment on a plant. They are trying to understand the role of chlorophyll in photosynthesis. According to their study, what does chlorophyll do in photosynthesis?

a)

Absorb light energy and convert it into chemical energy

b)

Regulate the temperature of the plant during photosynthesis

c)

Store excess water and nutrients for the plant
