Z-scheme is used for:
Correct answer: A. Non-Cyclic Photophosphorylation
- A. Non-Cyclic Photophosphorylation
- B. Cyclic Photophosphorylation
- C. Both Cyclic and Non-Cyclic Photophosphorylation
- D. Oxidative Phosphorylation
Explanation
The Z-scheme is a concept in photosynthesis that describes the electron flow through the photosystems during the light-dependent reactions. However, it is associated with cyclic and non-cyclic photophosphorylation.Non-cyclic photophosphorylation is the process in which light energy is used to generate both ATP (adenosine triphosphate) and NADPH (nicotinamide adenine dinucleotide phosphate) by linear electron flow. The Z-scheme illustrates the flow of electrons between two photosystems, Photosystem II (PSII) and Photosystem I (PSI), and other electron carriers in a zigzag or Z-shaped pattern.

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.
