Photosynthesis & Cellular Respiration Review

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.

Front

What are the main products of photosynthesis?

Back

The main products of photosynthesis are glucose and oxygen.

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 role of chlorophyll in photosynthesis?

Back

Chlorophyll is a green pigment found in chloroplasts that absorbs light energy, primarily from the sun, to drive the photosynthesis process.

Front

What are the two main stages of photosynthesis?

Back

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

Front

Where does the light-dependent reaction of photosynthesis occur?

Back

The light-dependent reactions occur in the thylakoid membranes of the chloroplasts.

Front

What is the Calvin Cycle?

Back

The Calvin Cycle is the light-independent stage of photosynthesis where carbon dioxide is fixed into glucose using ATP and NADPH produced in the light-dependent reactions.

Front

What is ATP and why is it important?

Back

ATP (adenosine triphosphate) is an energy-rich compound that stores and provides energy for various cellular processes.

Front

What molecule is broken down to release oxygen during photosynthesis?

Back

Oxygen is released during photosynthesis from the breakdown of water (H2O) in the light-dependent reactions.

Front

What is the primary source of carbon for the Calvin Cycle?

Back

The primary source of carbon for the Calvin Cycle is carbon dioxide (CO2) from the atmosphere.
