Enzymes

Front

What are enzymes?

Back

Enzymes are biological catalysts that speed up chemical reactions in living organisms without being consumed in the process.

Front

What is the optimal temperature for enzyme activity?

Back

The optimal temperature is the temperature at which an enzyme's activity is highest, often around 30°C for many enzymes.

Front

What is the active site of an enzyme?

Back

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

Front

Why are enzymes considered reusable?

Back

Enzymes are reusable because they are not consumed in the reaction; they can catalyze multiple reactions.

Front

What is the role of enzymes in biochemical reactions?

Back

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

Front

What is a substrate?

Back

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

Front

What are products in an enzymatic reaction?

Back

Products are the molecules that result from the enzymatic reaction after the substrate has been transformed.

Front

How do temperature changes affect enzyme activity?

Back

Temperature changes can affect enzyme activity; too high or too low temperatures can denature the enzyme, reducing its effectiveness.

Front

What is enzyme specificity?

Back

Enzyme specificity refers to the ability of an enzyme to choose exact substrate from a group of similar chemical molecules.

Front

What is denaturation in enzymes?

Back

Denaturation is the process in which an enzyme loses its functional shape due to external factors like temperature or pH changes.
