Biology I - Photosynthesis and Cell 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, 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. It occurs in both plants and animals.

Front

How do photosynthesis and cellular respiration relate to each other?

Back

Photosynthesis converts carbon dioxide and water into glucose and oxygen, while cellular respiration uses glucose and oxygen to produce energy, carbon dioxide, and water. They are interconnected processes.

Front

Where do the light-dependent reactions of photosynthesis occur?

Back

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

Front

What is the role of ATP in cellular processes?

Back

ATP (adenosine triphosphate) serves as the primary energy carrier in cells, providing energy for various cellular activities.

Front

What is the function of the thylakoid in photosynthesis?

Back

Thylakoids are membrane-bound structures within chloroplasts where the light-dependent reactions of photosynthesis take place.

Front

What is the electron transport chain (ETC)?

Back

The electron transport chain is a series of protein complexes located in the inner membrane of mitochondria that transfer electrons and pump protons to generate ATP.

Front

What are the products of photosynthesis?

Back

The products of photosynthesis are glucose and oxygen.

Front

What are the reactants of cellular respiration?

Back

The reactants of cellular respiration are glucose and oxygen.

Front

What is the significance of the stroma in chloroplasts?

Back

The stroma is the fluid-filled space in chloroplasts where the Calvin cycle (light-independent reactions) occurs, using ATP and NADPH produced in the light-dependent reactions.
