Chlorophyll a and b are found in a specific photosystems which photosystem contains chlorophyll a and which contains chlorophyll b?

Answer 1

I have studied photosyn. and to the best of my knowledge chl. a and b are in both photosystems. The difference between absorption in photosystem II (p680) and I (p700) is caused by the amount of a (best at 450-500nm) or b (best at 470-600nm).Photosyn. I should have more b and photosyn. should have more a.

Answer 2

They are pigments that absorb specific wavelengths of light to use in the photosynthetic process.

Chlorophyll gives plants their green colour because it reflects green light and absorbs red/orange and blue/violet.

Chlorophyll a is the main pigment involved in photosynthesis, it is found in plants, green algae and cyanobacteria and is essential for photosynthetic organisms to release chemical energy however, it is not the only pigment used for photosynthesis. All oxygenic photosynthetic organisms use Chlorophyll a but can differ in accessory pigments such as Chlorophyll b

Chlorophyll b is a form of Chlorophyll that helps with photosynthesis by absorbing blue light (primarily) and is yellow in colour.

Other accessory pigments include carotenes and xanthophylls (red/orange) and phycobilins (brown)

Answer 3

Chlorophyll a is found in both Photosystem I and Photosystem II, while Chlorophyll b is typically found in higher concentrations in Photosystem II compared to Photosystem I. Both Photosystem I and Photosystem II play important roles in the light-dependent reactions of photosynthesis.

Answer 4

they are in the thylakoid sac which is in the thylakoid membrane
