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 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

What is a substrate?

Back

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

Front

What is the enzyme-substrate complex?

Back

The enzyme-substrate complex is the temporary molecule formed when an enzyme comes into perfect contact with its substrate.

Front

What does it mean for an enzyme to be denatured?

Back

Denaturation is the process in which an enzyme loses its functional shape due to high temperature or extreme pH, rendering it inactive.

Front

What is the optimum pH for an enzyme?

Back

The optimum pH is the pH at which an enzyme's activity is at its maximum.

Front

What suffix do most enzymes have?

Back

Most enzymes typically end with the suffix '-ase', such as 'lactase' or 'amylase'.

Front

How does temperature affect enzyme activity?

Back

Enzyme activity generally increases with temperature up to a certain point (optimum temperature), after which it decreases due to denaturation.

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 role do enzymes play in metabolic pathways?

Back

Enzymes facilitate and regulate the biochemical reactions that occur in metabolic pathways, allowing for efficient energy production and resource utilization.
