Photosystem I absorbs maximum wavelength of light?
Correct answer: A. 700 nm
- A. 700 nm
- B. 600 nm
- C. 750 nm
- D. 770 nm
Explanation
Photosystem I, also known as P700, is optimized to absorb light at a wavelength of 700 nanometers. This specific wavelength is crucial for its function in the electron transport chain during photosynthesis, facilitating efficient energy capture and conversion. Other wavelengths like 600 nm, 750 nm, and 770 nm do not align with the absorption peak of Photosystem I, either falling short or exceeding the range in which Photosystem I operates most effectively.

About Bioenergetics
Cellular respiration explains how cells release energy from glucose through glycolysis, the link reaction, Krebs cycle and electron transport chain. It includes ATP production, substrate-level and oxidative phosphorylation, aerobic versus anaerobic respiration, and the roles of mitochondria, oxygen and fermentation in energy transfer.
