What are enzymes?

Back

Enzymes are proteins that speed up chemical reactions by lowering the amount of activation energy required to start the reaction.

Front

What happens to enzymes at high temperatures?

Back

Enzymes can denature, causing chemical reactions to slow down in the body.

Front

What is homeostasis?

Back

Homeostasis is the goal for all living organisms to maintain a balance and equilibrium.

Front

What is the induced fit mechanism?

Back

The induced fit mechanism describes how an enzyme changes shape once the substrate is bonded.

Front

What is an exothermic reaction?

Back

An exothermic reaction is a chemical reaction that releases energy in the form of heat.

Front

What is an endothermic reaction?

Back

An endothermic reaction is a chemical reaction that absorbs energy from its surroundings.

Front

What role do enzymes play in biological reactions?

Back

Enzymes act as catalysts to speed up biological reactions without being consumed in the process.

Front

What factors affect enzyme activity?

Back

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

Front

What is activation energy?

Back

Activation energy is the minimum amount of energy required to initiate a chemical reaction.

Front

What is a substrate in enzymatic reactions?

Back

A substrate is the reactant molecule upon which an enzyme acts.
