Photosynthesis and Respiration

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 is cellular respiration?

Back

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

Front

Which organisms perform both photosynthesis and cellular respiration?

Back

Organisms such as plants, algae, and some bacteria perform both photosynthesis and cellular respiration.

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, which is essential for photosynthesis.

Front

What are the two main stages of photosynthesis?

Back

The two main stages of photosynthesis are the Light Reactions and the Calvin Cycle.

Front

Where do the Light Reactions occur?

Back

The Light Reactions occur in the thylakoid membranes of the chloroplasts.

Front

What is produced during the Light Reactions?

Back

The Light Reactions produce ATP and NADPH, which are energy carriers used in the Calvin Cycle.

Front

What is the Calvin Cycle?

Back

The Calvin Cycle is the second stage of photosynthesis that occurs in the stroma of chloroplasts, where carbon dioxide is fixed into glucose using ATP and NADPH.

Front

What gas is taken in during photosynthesis?

Back

Carbon dioxide is taken in during photosynthesis.

Front

What gas is released during photosynthesis?

Back

Oxygen is released as a byproduct of photosynthesis.
