Photosynthesis - Practice Questions

Flashcards about Photosynthesis

Cyanobacteria

Organisms that can carry out photosynthesis.

Main purpose of photosynthesis

To convert solar energy into chemical energy.

Chloroplasts

Where photosynthesis takes place in plant cells.

Carbon dioxide

Gas consumed during photosynthesis.

Light reactions and Calvin cycle

The two main stages of photosynthesis.

Water

The oxygen released during photosynthesis comes from this molecule.

Glucose

The final product of the Calvin cycle.

ATP and NADPH

What is produced during the light-dependent reactions.

Water is split, releasing oxygen

Occurs in Photosystem II.

To produce NADPH

The role of Photosystem I in the light reactions.

Stroma of the chloroplast

Where the Calvin cycle takes place.

G3P (glyceraldehyde-3-phosphate)

Molecule directly produced by the Calvin cycle.

Rubisco

The enzyme involved in the fixation of carbon dioxide.

ATP and NADPH

What the light-dependent reactions produce.

Split water molecules and excite electrons

How the energy from sunlight is used directly.

Calvin cycle

ATP and NADPH produced in the light reactions are used in.

Thylakoid membrane

The structure within the chloroplast is the site of light-dependent reactions.

Grana

The stacks of thylakoids in a chloroplast are called.
