Read the following statements and choose the follwoing option: 1. In PS I the reaction centre chlorophyll a has an absorption peak at 800 2. In photosystem II the reaction centre chlorophyll a absorbs 680 nm wavelength 3. Each photosystem has all the pigments (except one molecule of chlorophyll a) forming a light harvesting system also called cytochrome 4. Accessory pigments facilitate photo-oxidation of chlorophyll

Options

  1. AOnly 2 is correct
  2. BOnly 3 is correct
  3. CAll are incorrect
  4. DOnly 1 is correct

Correct answer

A. Only 2 is correct

Step-by-step solution

In photosystem II the reaction centre chlorophyll a absorbs 680 nm wavelength of red light causing electrons to become excited and jump into an orbit farther from the atomic nucleus.
