Through CO₂ absorbed from the atmosphere

Front

During the Calvin Cycle, what is used to make glucose?

Back

ATP from the light dependent reactions is used to make glucose

Front

What is the role of NADPH in photosynthesis?

Back

NADPH provides the reducing power for the Calvin Cycle.

Front

What is the main purpose of the light-dependent reactions of photosynthesis?

Back

To convert solar energy into chemical energy (ATP and NADPH).

Front

What is chemiosmosis?

Back

The movement of ions across a selectively permeable membrane, down their electrochemical gradient.

Front

What is the function of the electron transport chain in cellular respiration?

Back

To transfer electrons and pump protons to create a proton gradient.

Front

What is the primary source of energy for cellular processes?

Back

ATP (Adenosine Triphosphate).
