Enzymes

Front

What is specificity in relation to enzymes?

Back

Specificity refers to the ability of an enzyme to catalyze a specific reaction for a particular substrate, meaning each enzyme only fits one type of substrate.

Front

What are enzymes made of?

Back

Enzymes are primarily made of proteins, not fatty acids.

Front

What happens to enzymes at high temperatures?

Back

High temperatures can denature enzymes, altering their shape and rendering them ineffective.

Front

What is the active site of an enzyme?

Back

The active site is the region on the enzyme where the substrate binds and the reaction occurs.

Front

What is the primary function of enzymes?

Back

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

Front

What is denaturation in enzymes?

Back

Denaturation is the process where an enzyme's structure is altered, usually due to extreme temperature or pH changes, affecting its function.

Front

What is a substrate in the context of enzymes?

Back

A substrate is the reactant molecule that an enzyme acts upon during a chemical reaction.

Front

What are products in an enzymatic reaction?

Back

Products are the substances that are formed as a result of the enzymatic reaction.

Front

How do enzymes affect the rate of chemical reactions?

Back

Enzymes increase the rate of chemical reactions by providing an alternative pathway with a lower activation energy.

Front

What is the role of temperature in enzyme activity?

Back

Enzymes have an optimal temperature range where they function best; outside this range, their activity can decrease or they can denature.
