the diagram is a representation of part of a plant cell. identify the locations where proton concentration builds up during photosynthesis and cellular respiration.
Answer
Answer:
During photosynthesis, proton concentration builds up in the thylakoid space. During cellular respiration, proton concentration builds up in the inter - membrane space of mitochondria.
Brief Explanation:
In photosynthesis, light - dependent reactions pump protons into thylakoid space. In cellular respiration, electron transport chain pumps protons into mitochondrial inter - membrane space.
