NADPH

Question 9

The membranes of the grana create a

Answer 9

large surface area to increase the number of light-dependent reactions that can occur

Question 10

The membranes of the grana create a large surface area to increase the number of light-dependent reactions that can occur

This membrane system provides a large number of pigment molecules in an arrangement that ensures

Answer 10

as much light as necessary is absorbed
