Front

What is the role of an enzyme in a chemical reaction?

Back

An enzyme speeds up a reaction by lowering the activation energy.

Front

What are the products of aerobic cellular respiration?

Back

ATP, Carbon dioxide (CO2), Water - All of the above.

Front

What is a limiting factor in a population?

Back

A limiting factor is a condition that restricts the growth, abundance, or distribution of an organism or a population of organisms, such as the presence of a natural predator.

Front

What is an abiotic factor?

Back

An abiotic factor is a non-living part of an ecosystem, such as a rock.

Front

What is the main job of electron carriers in cellular respiration?

Back

Transport electrons and hydrogen atoms to the electron transport chain.

Front

Define activation energy.

Back

Activation energy is the minimum energy required for a chemical reaction to occur.

Front

What is cellular respiration?

Back

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

Front

What is the difference between biotic and abiotic factors?

Back

Biotic factors are living components of an ecosystem, while abiotic factors are non-living components.

Front

What is the function of ATP in cells?

Back

ATP (adenosine triphosphate) serves as the primary energy carrier in cells.

Front

What is chemiosmosis?

Back

Chemiosmosis is the movement of ions across a selectively permeable membrane, down their electrochemical gradient, which is used to generate ATP.
