Light Reaction and Calvin Cycle

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll is the pigment in chloroplasts that absorbs light energy, primarily from the blue and red wavelengths, to facilitate photosynthesis.

Front

Why do leaves appear green?

Back

Leaves appear green because chlorophyll reflects green light and absorbs other wavelengths of light.

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 the chloroplasts.

Front

What are the main products of the light reactions?

Back

The main products of the light reactions are ATP, NADPH, and oxygen.

Front

What is the stroma in a chloroplast?

Back

The stroma is the fluid-filled interior space of the chloroplast where the Calvin Cycle takes place.

Front

What is the main product of the Calvin Cycle?

Back

The main product of the Calvin Cycle is glucose.

Front

Which molecule is NOT produced during the light reactions?

Back

Glucose is NOT produced during the light reactions.

Front

What is the function of ATP in photosynthesis?

Back

ATP provides the energy needed for the Calvin Cycle to synthesize glucose from carbon dioxide.

Front

What is the function of NADPH in photosynthesis?

Back

NADPH provides the reducing power (electrons) needed for the Calvin Cycle to convert carbon dioxide into glucose.
