The formation of ATP during non-cyclic electron flow is called
Correct answer: C. Non-cyclic phosphorylation
- A. Z - scheme
- B. Light reaction
- C. Non-cyclic phosphorylation
- D. Synthesis of ATP and NADPH2
Explanation
In photosynthesis, non-cyclic phosphorylation refers to the process where electrons flow from water through Photosystem II and Photosystem I, ultimately reducing NADP⁺ to NADPH and synthesizing ATP. Unlike cyclic phosphorylation, the electrons are not recycled back to the photosystem. Option C is correct because it specifically describes this electron flow process. Option A describes the model of electron flow rather than the ATP formation process, Option B is too general, encompassing both cyclic and non-cyclic processes, and Option D describes the products of the process rather than the process itself.

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.
