The four main types of biomolecules are proteins, nucleic acids, carbohydrates, and lipids.

Front

What is the primary function of enzymes?

Back

Enzymes act as catalysts to speed up chemical reactions in biological processes.

Front

What are amino acids?

Back

Amino acids are the building blocks of proteins, consisting of an amino group, a carboxyl group, and a unique side chain.

Front

What is the role of the active site in an enzyme?

Back

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

Front

What factors can affect enzyme activity?

Back

Enzyme activity can be affected by temperature, pH, substrate concentration, and the presence of inhibitors or activators.

Front

What is the optimum pH for most enzymes?

Back

Most enzymes have an optimum pH around neutral (pH 7), but some may function best at acidic or basic pH levels.

Front

What are lipids?

Back

Lipids are a group of biomolecules that include fats, oils, and waxes, known for their high energy content and hydrophobic nature.

Front

How do carbohydrates function in the body?

Back

Carbohydrates provide a primary source of energy for the body and are involved in cell structure and signaling.

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.
