Dec 10 Photosynthesis Review

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, and releasing oxygen as a byproduct.

Front

What role do enzymes play in metabolic reactions?

Back

Enzymes are biological catalysts that decrease the energy needed to start a reaction, thereby increasing the speed of metabolic reactions.

Front

What are stomata?

Back

Stomata are small openings found on the surfaces of leaves that allow for gas exchange, enabling carbon dioxide to enter and oxygen to exit the plant.

Front

How does low carbon dioxide affect photosynthesis?

Back

Low levels of carbon dioxide in the atmosphere can slow down the process of photosynthesis, as carbon dioxide is a key reactant.

Front

What is the chemical formula for glucose?

Back

The chemical formula for glucose is C6H12O6.

Front

What gases enter and exit plants during photosynthesis?

Back

During photosynthesis, carbon dioxide enters the plant, and oxygen exits.

Front

What is chlorophyll?

Back

Chlorophyll is a green pigment found in plants that absorbs light energy, primarily from the sun, and is essential for photosynthesis.

Front

What is the significance of light in photosynthesis?

Back

Light provides the energy required for photosynthesis to occur, enabling plants to convert carbon dioxide and water into glucose and oxygen.

Front

What is the role of water in photosynthesis?

Back

Water is a reactant in photosynthesis, providing electrons and protons needed for the formation of glucose and oxygen.

Front

What is the overall equation for photosynthesis?

Back

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