AP Bio Photosynthesis

Front

What is the process of 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 by-product.

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 of photosynthesis occur?

Back

The light reactions occur in the thylakoid membranes of chloroplasts.

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll is a pigment that absorbs light energy, primarily in the blue and red wavelengths, and plays a crucial role in converting light energy into chemical energy.

Front

What is produced during the light reactions of photosynthesis?

Back

The light reactions produce ATP, NADPH, and oxygen.

Front

What is the Calvin cycle also known as?

Back

The Calvin cycle is also known as the light-independent reactions or dark reactions.

Front

What is the primary function of the Calvin cycle?

Back

The primary function of the Calvin cycle is to produce simple sugars (glucose) from carbon dioxide.

Front

What is the significance of splitting water molecules in photosynthesis?

Back

Splitting water molecules provides electrons for the electron transport chain and releases oxygen as a by-product.

Front

What is ATP Synthase and its role in photosynthesis?

Back

ATP Synthase is an enzyme that synthesizes ATP from ADP and inorganic phosphate, using the energy from the flow of hydrogen ions (H+) across the thylakoid membrane.

Front

What happens if the proton pump in the thylakoid is not functioning?

Back

If the proton pump is not functioning, ATP cannot be produced during the light reactions.
