Enzymes

Front

What are enzymes primarily made of?

Back

Proteins

Front

What is the term for the complex formed when an enzyme binds to its substrate?

Back

Enzyme-substrate complex

Front

What effect does high temperature have on enzymes?

Back

It denatures them, altering their shape.

Front

Do all enzymes have an optimal temperature and pH?

Back

Yes, every enzyme has specific optimal conditions.

Front

What is the primary function of enzymes in biological reactions?

Back

To speed up reactions.

Front

What is the term for the specific region on an enzyme where the substrate binds?

Back

Active site

Front

What is enzyme denaturation?

Back

The process where an enzyme loses its functional shape due to external factors like heat or pH.

Front

How does pH affect enzyme activity?

Back

Each enzyme has an optimal pH range; deviations can reduce activity or denature the enzyme.

Front

What is a cofactor in relation to enzymes?

Back

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

Front

What is the difference between competitive and non-competitive inhibitors?

Back

Competitive inhibitors bind to the active site, while non-competitive inhibitors bind to another part of the enzyme.
