Question

Which stage(s) of photosynthesis and/or cellular respiration requires glucose? 1.glycolysis and Calvin cycle only 2. electron transport chain and light reaction 3. glycolysis only 4. Calvin cycle only

Answer 1

Glucose is required in the glycolysis stage of cellular respiration and the Calvin cycle of photosynthesis. In glycolysis, glucose is converted into pyruvate yielding energy while in the Calvin Cycle, glucose is formed using energy from light-dependent reactions.

Step-by-step explanation:

The glycolysis stage of cellular respiration and the Calvin cycle stage of photosynthesis both require glucose. Glycolysis is an anaerobic phase in the cellular respiration process where glucose is converted into pyruvate, releasing energy in the form of ATP. The Calvin Cycle, also known as the light-independent or dark reactions of photosynthesis, uses the energy stored during the light-dependent reactions to convert carbon dioxide from the atmosphere into glucose. Therefore, the correct answer would be option 1: glycolysis and Calvin cycle only.
