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

Where do the light-dependent reactions occur?

Back

The light-dependent reactions occur in the thylakoids, which are part of the chloroplast.

Front

What is the main product of the light-dependent reactions?

Back

The main products of the light-dependent reactions are ATP (adenosine triphosphate) and NADPH (nicotinamide adenine dinucleotide phosphate).

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll is a pigment found in chloroplasts that absorbs light energy, primarily from the sun, which is essential for photosynthesis.

Front

What is the Calvin cycle?

Back

The Calvin cycle is a series of biochemical reactions that occur in the stroma of chloroplasts, where carbon dioxide is fixed into glucose using ATP and NADPH produced in the light-dependent reactions.

Front

How is photosynthesis related to cellular respiration?

Back

Photosynthesis produces glucose and oxygen, which are used in cellular respiration to produce energy (ATP), while cellular respiration produces carbon dioxide and water, which are used in photosynthesis.

Front

What is the equation for photosynthesis?

Back

The equation for photosynthesis is 6CO2 + 6H2O + light energy → C6H12O6 + 6O2.

Front

What are thylakoids?

Back

Thylakoids are membrane-bound compartments inside chloroplasts that contain chlorophyll and are the site of the light-dependent reactions of photosynthesis.

Front

What is anaerobic respiration?

Back

Anaerobic respiration is a type of respiration that occurs without oxygen, producing energy through processes like fermentation.

Front

What is the Kreb’s cycle?

Back

The Kreb’s cycle, also known as the citric acid cycle, is a series of chemical reactions used by all aerobic organisms to generate energy through the oxidation of acetyl-CoA.
