Front

What is Cellular Respiration?

Back

Cellular Respiration is the process by which cells convert chemical energy from nutrients into ATP (adenosine triphosphate), releasing waste products.

Front

What happens when an enzyme denatures?

Back

When an enzyme denatures, it loses its shape due to changes in temperature or pH, rendering it unable to function.

Front

What biomolecule do enzymes belong to?

Back

Enzymes are proteins that act as catalysts in biochemical reactions.

Front

Define Mutualism in ecology.

Back

Mutualism is a symbiotic relationship where both species benefit from the interaction.

Front

Define Commensalism in ecology.

Back

Commensalism is a symbiotic relationship where one species benefits and the other is neither helped nor harmed.

Front

Define Parasitism in ecology.

Back

Parasitism is a symbiotic relationship where one organism benefits at the expense of another.

Front

What is the role of enzymes in biological reactions?

Back

Enzymes speed up chemical reactions by lowering the activation energy required for the reaction to occur.

Front

What factors can affect enzyme activity?

Back

Factors include temperature, pH, substrate concentration, and the presence of inhibitors or activators.

Front

What is the significance of ATP in cellular processes?

Back

ATP (adenosine triphosphate) is the primary energy carrier in cells, providing energy for various biological processes.

Front

What is the difference between aerobic and anaerobic respiration?

Back

Aerobic respiration requires oxygen and produces more ATP, while anaerobic respiration occurs without oxygen and produces less ATP.
