The absorption spectrum in the given diagram will be of:
1. | Chlorophyll a | 2. | Chlorophyll b |
3. | Carotenoids | 4. | Retinol |
The reactions of the Calvin Cycle occur in:
1. | stroma of the chloroplast |
2. | thylakoid membrane |
3. | lumen of the thylakoids |
4. | space between outer and inner membrane of the chloroplast |
The wavelengths of light most useful in photosynthesis are:
1. | green and orange | 2. | red and blue |
3. | infrared and yellow | 4. | red and green |
The correct chronological sequence of protein complexes in the thylakoid membrane involved in light reactions is:

Oxygen, during oxygenic photosynthesis, is produced during:
1. cyclic photophosphorylation
2. the light-dependent reactions involving photosystems I and II
