Photosynthesis

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 the role of RuBisCo in photosynthesis?

Back

RuBisCo (Ribulose Bisphosphate Carboxylase) is an enzyme that catalyzes the fixation of carbon dioxide from the atmosphere, converting it into a complex macromolecule, glucose.

Front

What are the two main stages of photosynthesis?

Back

The two main stages of photosynthesis are the light-dependent reactions and the light-independent reactions (Calvin cycle).

Front

Where do light-dependent reactions occur?

Back

Light-dependent reactions occur in the thylakoid membranes of the chloroplasts.

Front

What is produced during the light-dependent reactions?

Back

The light-dependent reactions produce ATP and NADPH, which are essential for the Calvin cycle.

Front

What is the function of ATP in photosynthesis?

Back

ATP (Adenosine Triphosphate) serves as an energy carrier, providing the energy needed for various biochemical reactions during the Calvin cycle.

Front

What is the function of NADPH in photosynthesis?

Back

NADPH (Nicotinamide Adenine Dinucleotide Phosphate) acts as a reducing agent, providing the electrons needed for the conversion of carbon dioxide into glucose during the Calvin cycle.

Front

What is the Calvin cycle?

Back

The Calvin cycle is the light-independent stage of photosynthesis where carbon dioxide is fixed and converted into glucose using ATP and NADPH.

Front

Where does the Calvin cycle take place?

Back

The Calvin cycle takes place in the stroma of the chloroplasts.

Front

What are grana in chloroplasts?

Back

Grana are stacks of thylakoid membranes within chloroplasts where the light-dependent reactions of photosynthesis occur.
