Enzymes

Front

What is an enzyme?

Back

An enzyme is a biological catalyst that speeds up chemical reactions in living organisms by lowering the activation energy required for the reaction.

Front

What is the active site of an enzyme?

Back

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

Front

What is a substrate?

Back

A substrate is any substance that is acted upon by an enzyme during a chemical reaction.

Front

What does specificity mean in relation to enzymes?

Back

Specificity refers to the ability of an enzyme to select and bind to a particular substrate, meaning each enzyme typically catalyzes only one type of reaction.

Front

What is activation energy?

Back

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

Front

What happens to enzymes during denaturation?

Back

Denaturation is the process where an enzyme loses its three-dimensional structure and, consequently, its functionality due to factors like extreme pH or temperature.

Front

How do enzymes affect reaction rates?

Back

Enzymes increase the rate of chemical reactions by lowering the activation energy needed for the reaction to occur.

Front

What is a coenzyme?

Back

A coenzyme is a non-protein organic molecule that assists enzymes in catalyzing reactions, often by acting as a carrier for chemical groups.

Front

What role do enzymes play in metabolism?

Back

Enzymes facilitate metabolic reactions by speeding up the conversion of substrates into products, thus regulating the metabolic pathways.

Front

What is enzyme reusability?

Back

Enzymes are reusable; they are not consumed in the reaction and can catalyze multiple reactions without being altered.
