Question

events listed are parts of the overall process of photosynthesis. for each event, identify the chloroplast structure that litates the event. each structure may be used once, more than once, or not at all. light - dependent reactions co₂ - dependent reactions calvin cycle atp production answer bank stroma thylakoid membrane

Explanation:

• Light - dependent reactions: These reactions occur in the thylakoid membrane. Chlorophyll and other pigments embedded in the thylakoid membrane absorb light energy. This energy is used to split water molecules (photolysis) and generate ATP and NADPH.
• \(CO_2\) - dependent reactions: Also known as the light - independent reactions (Calvin cycle), these occur in the stroma. In the stroma, \(CO_2\) is fixed and converted into organic molecules (such as glucose) using the ATP and NADPH generated in the light - dependent reactions.
• Calvin cycle: As mentioned above, it is a part of the \(CO_2\) - dependent reactions and takes place in the stroma.
• ATP production: During the light - dependent reactions, which occur in the thylakoid membrane, ATP is produced through chemiosmosis. The electron transport chain in the thylakoid membrane creates a proton gradient, and ATP synthase (also in the thylakoid membrane) uses this gradient to synthesize ATP from ADP and inorganic phosphate.

Answer:

• light - dependent reactions: thylakoid membrane
• \(CO_2\) - dependent reactions: stroma
• Calvin cycle: stroma
• ATP production: thylakoid membrane
