Enzymes

Front

What are enzymes?

Back

Enzymes are biological catalysts that speed up chemical reactions in living organisms.

Front

How do enzymes affect the speed of reactions?

Back

Enzymes make reactions go faster and use less energy.

Front

What is the optimum pH for an enzyme?

Back

The optimum pH is the pH at which an enzyme is most active; for some enzymes, it can be around 6.6.

Front

What happens to enzyme activity as pH changes?

Back

Enzyme activity can increase or decrease with changes in pH, often peaking at an optimum pH.

Front

What is the function of an enzyme?

Back

Enzymes speed up chemical reactions by lowering the activation energy required.

Front

What happens to enzymes at high temperatures?

Back

High temperatures can alter the shape of enzymes, affecting their function.

Front

What is the active site of an enzyme?

Back

The active site is the region on the enzyme where substrate molecules bind and undergo a chemical reaction.

Front

What is a substrate?

Back

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

Front

What is an enzyme-substrate complex?

Back

An enzyme-substrate complex is formed when an enzyme binds to its substrate.

Front

What is denaturation in enzymes?

Back

Denaturation is the process where an enzyme loses its functional shape due to extreme conditions, such as high temperature or pH.
