Photosynthesis and Cellular Respiration Test 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 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 chloroplasts in photosynthesis?

Back

Chloroplasts are organelles in plant cells that contain chlorophyll and are responsible for capturing light energy to drive the process of photosynthesis.

Front

What is the role of mitochondria in cellular respiration?

Back

Mitochondria are organelles in cells that convert the chemical energy stored in glucose into ATP through the process of cellular respiration.

Front

What is ATP and why is it important?

Back

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

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

How do photosynthesis and cellular respiration relate to each other?

Back

Photosynthesis produces glucose and oxygen, which are used in cellular respiration to produce ATP, while cellular respiration releases carbon dioxide and water, which are used in photosynthesis.

Front

What is the significance of the light-dependent reactions in photosynthesis?

Back

Light-dependent reactions convert light energy into chemical energy (ATP and NADPH) and occur in the thylakoid membranes of chloroplasts.

Front

What is the significance of the Krebs cycle in cellular respiration?

Back

The Krebs cycle (Citric Acid Cycle) is a series of chemical reactions used by all aerobic organisms to generate energy through the oxidation of acetyl-CoA.
