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 are the main products of the light reactions of photosynthesis?

Back

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

Front

Which molecule is responsible for the green color in leaves?

Back

Chlorophyll is the molecule that gives leaves their green color and is essential for photosynthesis.

Front

Where do the light reactions of photosynthesis occur?

Back

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

Front

What is the role of RuBisCo in photosynthesis?

Back

RuBisCo (Ribulose Bisphosphate Carboxylase) is an enzyme that catalyzes the first step of carbon fixation in the Calvin cycle, converting carbon dioxide into organic molecules.

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 Calvin cycle?

Back

The Calvin cycle is the set of chemical reactions that take place in the stroma of chloroplasts during photosynthesis, where carbon dioxide is converted into glucose.

Front

What is ATP and why is it important in photosynthesis?

Back

ATP (Adenosine Triphosphate) is the energy currency of the cell, providing the energy needed for various biochemical reactions, including those in photosynthesis.

Front

What is NADPH and its role in photosynthesis?

Back

NADPH (Nicotinamide Adenine Dinucleotide Phosphate) is a reducing agent that provides the high-energy electrons needed for the reduction of carbon compounds in the Calvin cycle.

Front

What is the significance of oxygen production in photosynthesis?

Back

Oxygen produced during photosynthesis is a byproduct that is released into the atmosphere, which is essential for the survival of aerobic organisms.
