Photosynthesis Practice

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 photosynthesis?

Back

The main products of photosynthesis are glucose (C6H12O6) and oxygen (O2).

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll is a green pigment found in plants that absorbs light energy, primarily from the sun, which is essential for the process of 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 and converted into glucose using ATP and NADPH.

Front

What is the chemical equation for photosynthesis?

Back

6CO2 + 6H2O + light energy -> C6H12O6 + 6O2.

Front

What is an autotroph?

Back

An autotroph is an organism that produces its own food from inorganic substances, using light or chemical energy; examples include plants and some bacteria.

Front

What is the function of ATP in photosynthesis?

Back

ATP (adenosine triphosphate) provides the energy required for various biochemical reactions in the Calvin Cycle.

Front

What is the role 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

Where does the light-dependent reaction of photosynthesis occur?

Back

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

Front

What is the significance of water in photosynthesis?

Back

Water is essential for photosynthesis as it provides electrons and protons, and its splitting releases oxygen as a byproduct.
