Question

In what way are the light-dependent and light-independent reactions of photosynthesis similar? Both require chemical energy to proceed. Both occur in the chloroplast. Both produce oxygen as a byproduct. Both involve carbon fixation.

Answer 1

## Step 1The light-dependent and light-independent reactions of photosynthesis are two stages of the process of photosynthesis. They are similar in that they both occur in the chloroplasts of plant cells.## Step 2The light-dependent reactions require light to produce ATP and NADPH. These reactions occur in the thylakoid membrane of the chloroplasts.## Step 3The light-independent reactions, also known as the Calvin cycle, do not require light. They use the ATP and NADPH produced by the light-dependent reactions to convert carbon dioxide into glucose. These reactions occur in the stroma of the chloroplasts.## Step 4The options suggesting that both reactions require chemical energy, produce oxygen, or involve carbon fixation are incorrect. Only the light-dependent reactions require chemical energy in the form of light. Oxygen is only produced during the light-dependent reactions, not the light-independent ones. Carbon fixation only occurs during the light-independent reactions.
