In the 'non-cyclic electron transport of light reaction', the deficit of _ electrons occur in the chlorophyll, as it absorbs energy
Correct answer: B. 2
- A. 1
- B. 2
- C. 3
- D. 4
Explanation
In the non-cyclic electron transport of the light reaction, also known as the Z-scheme, the deficit of electrons occurs in the chlorophyll molecule (specifically, chlorophyll a) as it absorbs energy from light. This energy excites an electron, which is then transferred to a special molecule called an electron acceptor, leaving a deficit of two electrons in the chlorophyll molecule.

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.
