Question

photosynthetic algae create sugars that will eventually be broken down during which process?
glycolysis, during respiration
the calvin cycle, during photosynthesis
electron transport chain, during respiration
the krebs cycle, during photosynthesis

Explanation:

• Glycolysis during respiration: This is the first step of cellular respiration. It breaks down glucose (sugar) into pyruvate, releasing some energy.
• Calvin cycle during photosynthesis: This is part of photosynthesis where carbon fixation occurs (building sugars, not breaking them down).
• Electron transport chain during respiration: This is the final step of respiration where most ATP is produced, but it doesn't directly break down the sugar (it uses electrons from previous steps like glycolysis and Krebs cycle).
• Krebs cycle during photosynthesis: The Krebs cycle is part of respiration, not photosynthesis. It further breaks down pyruvate (from glycolysis) to release more energy - related molecules.

Answer:

glycolysis, during respiration
