Photosynthesis and Cellular Respiration 3-6

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy into chemical energy in the form of glucose, using carbon dioxide and water, and releasing oxygen as a byproduct.

Front

What are the main stages of photosynthesis?

Back

The main stages of photosynthesis are the light-dependent reactions and the light-independent reactions (Calvin cycle).

Front

What is cellular respiration?

Back

Cellular respiration is the process by which cells convert glucose and oxygen into energy (ATP), carbon dioxide, and water.

Front

What is the equation for photosynthesis?

Back

6CO₂ + 6H₂O + light energy → C₆H₁₂O₆ + 6O₂.

Front

What is the equation for cellular respiration?

Back

C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O + ATP.

Front

What role do chloroplasts play in photosynthesis?

Back

Chloroplasts are the organelles in plant cells where photosynthesis occurs, containing chlorophyll that captures light energy.

Front

What is the significance of the Calvin cycle?

Back

The Calvin cycle is the set of light-independent reactions in photosynthesis that convert carbon dioxide into glucose using ATP and NADPH.

Front

What is the role of ATP in cellular respiration?

Back

ATP (adenosine triphosphate) is the main energy currency of the cell, providing energy for various cellular processes.

Front

What is the proton-motive force?

Back

The proton-motive force is the force generated by the transmembrane proton gradient, which drives ATP synthesis during cellular respiration.

Front

What is cyclic electron flow in photosynthesis?

Back

Cyclic electron flow is a process in photosynthesis where electrons are recycled in Photosystem I to produce additional ATP without producing NADPH.
