Answer #1

1. (e) C and D

Light reactions use light energy to make energy which is used in the next step- ATP and NADPH are energy molecules which are made in light reactions. Light reactions occurs in plants in the thylakoid membrane.

2. (b) Chlorophyll a.

Chlorophyll is most abundant in plants. It is universal pigment. Chlorophyll a absorbs light in wavelength of 432 and 662.

3. (d) Magnesium

Magnesium is the center atom which is surrounded by 4 nitrigen atom and otherv side chains along with a hydrocarbon tail.

Kindly give a thumbs up. Thank-you!!
