Front

What are enzymes?

Back

Enzymes are proteins that act as biological catalysts, speeding up chemical reactions in living organisms.

Front

What is the primary function of enzymes?

Back

The primary function of enzymes is to lower the activation energy of a reaction, allowing it to proceed more quickly.

Front

What is a substrate?

Back

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

Front

What is the active site of an enzyme?

Back

The active site is the specific region of an enzyme where the substrate binds and the reaction occurs.

Front

What is an enzyme-substrate complex?

Back

An enzyme-substrate complex is formed when an enzyme binds to its substrate, facilitating the conversion of substrate to product.

Front

What factors affect enzyme activity?

Back

Factors that affect enzyme activity include temperature, pH, substrate concentration, and enzyme concentration.

Front

What happens to enzymes at high temperatures?

Back

At high temperatures, enzymes can denature, losing their shape and functionality.

Front

What is enzyme specificity?

Back

Enzyme specificity refers to the ability of an enzyme to catalyze only one specific type of reaction or act on a specific substrate.

Front

What are products in a chemical reaction?

Back

Products are the substances that are formed as a result of a chemical reaction.

Front

What is the role of coenzymes?

Back

Coenzymes are non-protein molecules that assist enzymes in catalyzing reactions, often by acting as carriers for chemical groups.
