Question

select all of the following that occur in the light-dependent reactions.

check all that apply

□ carbon fixation takes place

□ glucose is produced

□ atp is synthesized via chemiosmosis

□ nadph is oxidized to nadp+

Explanation:

1. Carbon fixation: Occurs in the light - independent (Calvin cycle) reactions, not light - dependent. So this is incorrect.
2. Glucose production: Glucose is produced in the light - independent reactions (Calvin cycle) from the fixed carbon. So this is incorrect.
3. ATP synthesis via chemiosmosis: In light - dependent reactions, during the electron transport chain, a proton gradient is created. ATP synthase uses this gradient (chemiosmosis) to synthesize ATP. So this is correct.
4. NADP⁺ to NADPH: In the light - dependent reactions, electrons from the splitting of water and the electron transport chain are used to reduce NADP⁺ to NADPH. So this is correct.

Answer:

• ATP is synthesized via chemiosmosis
• NADP⁺ is converted to NADPH
