Chlorophyll a Absorption Peaks — NEET Biology
📚 Practice ConceptFrom can you determine the wavelength (colour of light) at which chlorophyll a shows the maximum absorption? Does it show another absorption peak at any other wavelengths too? If yes, which one?
Which of the following statements about the conversion of light energy into chemical energy during photosynthesis are correct? S1: Chlorophyll a in the reaction center of Photosystem II is known as P700 due to its absorption maximum at 700 nm wavelength. S2: The energy released from the breakdown of the proton gradient across the thylakoid membrane is utilized by ATP synthase to produce ATP. S3: Cyclic photophosphorylation involves both Photosystem I and Photosystem II, resulting in the synthesis of both ATP and NADPH. S4: Water splitting primarily occurs on the outer side of the thylakoid membrane, releasing protons into the stroma. S5: Accessory pigments broaden the range of light wavelengths absorbed and protect chlorophyll a from photo-oxidation.
