What is the role of chloroplasts in plant cells?

Back

Chloroplasts convert radiant energy from sunlight into chemical energy through photosynthesis.

Front

What processes are important for the transfer and transformation of energy in living cells?

Back

Photosynthesis and cellular respiration are crucial for energy transfer and transformation in living cells.

Front

What role do enzymes play in metabolic reactions?

Back

Enzymes act as catalysts, speeding up metabolic reactions without being consumed.

Front

What is the main purpose of cellular respiration in living cells?

Back

The main purpose of cellular respiration is to store energy in a useful form.

Front

Which macromolecules are made by cells for life processes?

Back

Cells produce carbohydrates, proteins, nucleic acids, and lipids for various life processes.

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants use sunlight to synthesize foods with the help of chlorophyll.

Front

What is cellular respiration?

Back

Cellular respiration is the process by which cells convert glucose and oxygen into energy, carbon dioxide, and water.

Front

What are the two main stages of photosynthesis?

Back

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

Front

What is the function of ATP in cells?

Back

ATP (adenosine triphosphate) serves as the primary energy carrier in cells, providing energy for various cellular processes.

Front

What is a catalyst?

Back

A catalyst is a substance that increases the rate of a chemical reaction without undergoing any permanent change itself.
