Question

1. chlorophyll is a pigment found in chloroplasts that

a. reflects green light.
b. absorbs green light.
c. stores light energy.
d. makes up the stroma.

1. high - energy electrons are transported from chlorophyll to other molecules in the chloroplast by

a. the thylakoid membranes.
b. pigments such as carotene.
c. electron carriers such as nadp+.
d. the protein atp synthase.

Explanation:

Question 7

Chlorophyll appears green because it reflects green light and absorbs light in the red and blue regions of the spectrum. It does not store light energy (it converts it), and it is not part of the stroma (the stroma is the fluid - filled space in the chloroplast).

Electron carriers such as \(NADP^{+}\) (nicotinamide adenine dinucleotide phosphate) are responsible for transporting high - energy electrons from chlorophyll. Thylakoid membranes are the site of the light - dependent reactions but not the transporters. Pigments like carotene are accessory pigments that help in light absorption. ATP synthase is involved in ATP synthesis, not electron transport.

Answer:

A. reflects green light.
