Final answer:
The Krebs Cycle does not use NADPH produced during the Light Reaction; the Calvin cycle utilizes NADPH for the reduction of carbon dioxide, while the Krebs Cycle, part of cellular respiration, produces NADH and FADH2.
Step-by-step explanation:
The NADPH produced during the Light Reaction is not utilized in the Krebs Cycle. the student's question is c) Krebs Cycle.
NADPH is a product of the light-dependent reactions of photosynthesis (also called the Light Reaction) and serves as an electron donor for the light-independent reactions (often referred to as the Dark Reactions or the Calvin cycle). During the Calvin cycle, NADPH provides the necessary electrons for the reduction of carbon dioxide into glucose. In contrast, the Krebs Cycle is a part of cellular respiration that takes place in the mitochondria of cells and does not use the NADPH produced in photosynthesis. Instead, it produces its own electron carriers, namely NADH and FADH2, which funnel electrons into the electron transport chain to ultimately generate ATP.
The NADPH produced during the Light Reaction is not used in the Krebs Cycle. The Krebs Cycle, also known as the citric acid cycle or tricarboxylic acid cycle, is part of cellular respiration and takes place in the mitochondria. During the Krebs Cycle, NADH is produced instead of NADPH. NADPH is utilized predominantly in the Calvin cycle, also known as the light-independent reaction, to power the reduction of carbon dioxide into sugars.
