Biomolecules and Enzymes

Front

What is an enzyme?

Back

An enzyme is a biological catalyst that speeds up chemical reactions in living organisms by lowering the activation energy required for the reaction.

Front

What are carbohydrates?

Back

Carbohydrates are biomolecules that include sugars, starches, and cellulose, and are primarily used for energy storage and supply in living organisms.

Front

What is a substrate in the context of enzymes?

Back

A substrate is the reactant molecule upon which an enzyme acts, binding to the enzyme's active site to form a product.

Front

What do nucleic acids store?

Back

Nucleic acids store genetic information, which is essential for the synthesis of proteins and the transmission of hereditary traits.

Front

What are lipids?

Back

Lipids are a group of biomolecules that include fats, oils, and waxes, primarily used for energy storage, insulation, and making up cell membranes.

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 the role of enzymes in biological reactions?

Back

Enzymes facilitate and accelerate biochemical reactions without being consumed in the process.

Front

What are the products of an enzymatic reaction?

Back

Products are the substances that are formed as a result of the enzymatic reaction after the substrate has been transformed.

Front

How do temperature and pH affect enzyme activity?

Back

Enzyme activity can be affected by temperature and pH; extreme conditions can denature the enzyme, reducing its effectiveness.

Front

What is the difference between saturated and unsaturated fats?

Back

Saturated fats contain no double bonds between carbon atoms, while unsaturated fats contain one or more double bonds, affecting their physical properties.
