What is an enzyme?

Back

An enzyme is a biological catalyst that speeds up chemical reactions in living organisms.

Front

What is the role of enzymes in biological reactions?

Back

Enzymes lower the activation energy required for a reaction, allowing it to occur more quickly.

Front

What is a substrate?

Back

A substrate is any substance that is acted upon by an enzyme.

Front

What is the active site of an enzyme?

Back

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

Front

What happens to enzymes after a reaction?

Back

Enzymes are not consumed in the reaction and can be reused multiple times.

Front

What is a coenzyme?

Back

A coenzyme is a non-protein molecule that assists enzymes in catalyzing reactions.

Front

What is the difference between an enzyme and a catalyst?

Back

All enzymes are catalysts, but not all catalysts are enzymes. Enzymes are biological catalysts.

Front

What is the significance of enzyme specificity?

Back

Enzyme specificity means that each enzyme only catalyzes a specific reaction or acts on a specific substrate.

Front

What factors affect enzyme activity?

Back

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

Front

What is an enzyme inhibitor?

Back

An enzyme inhibitor is a substance that decreases the activity of an enzyme.
