During the light-dependent reactions of photosynthesis, what is the primary role of water?
During the light-dependent reactions of photosynthesis, what is the primary role of water?
- To transport hydrogen ions ($H^+$) into the stroma for ATP synthase.
- To directly fix carbon dioxide into glucose.
- To absorb excess light energy to prevent damage to chlorophyll.
- To provide electrons to replace those lost by chlorophyll in Photosystem II, and to produce oxygen. (correct)

What is the main purpose of the Calvin cycle in photosynthesis?
- To split water molecules and release oxygen.
- To regenerate NADP+ and ADP for the light-dependent reactions.
- To use ATP and NADPH to convert carbon dioxide into glucose. (correct)
- To capture light energy and convert it into chemical energy.

Energy
Energy
Energy is defined as the ability to do work.
ATP and ADP
ATP and ADP
ATP (adenosine triphosphate) is the primary energy currency of the cell. ADP (adenosine diphosphate) is what remains after ATP releases energy.
Autotrophs vs. Heterotrophs
Autotrophs vs. Heterotrophs
Autotrophs make their own food using energy from sunlight or chemical energy, while heterotrophs obtain energy by consuming other organisms.
