Detailed explanation-1: -Which compound is a metabolic intermediate of the light-independent reactions in photosynthesis? of the light-independent reactions in photosynthesis is RuBisCO.

Detailed explanation-2: -The light-dependent reactions synthesise ATP and the reductant NADPH. Subsequently, the ‘light-independent reactions’ use that NADPH and ATP to reduce and phosphorylate oxidized atmospheric carbon to the level of a sugar phosphate.

Detailed explanation-3: -Most plants use the Calvin cycle to fix CO2. To begin the Calvin cycle, a molecule of CO2 reacts with a five-carbon compound called ribulose bisphosphate (RuBP) producing an unstable six-carbon intermediate which immediately breaks down into two molecules of the three-carbon compound phosphoglycerate (PGA).

Detailed explanation-4: -Acetaldehyde is a metabolic intermediate in humans. It has been identified in food, beverages, and cigarette smoke. Acetaldehyde is metabolized primarily in the liver to a lesser extent in renal tubules by acetaldehyde dehydrogenase.

Detailed explanation-5: -3-phosphoglycerate. a three-carbon molecule that is a metabolic intermediate of light-independent reactions. Chemical energy is stored in ATP and NADPH is transferred to 3-PGA to form the high-energy molecule glyceraldehyde 3-phosphate (G3P). ATP supplies the phosphate group.
