What are macromolecules?

Back

Large, complex molecules essential for life, including carbohydrates, proteins, lipids, and nucleic acids.

Front

What is a monosaccharide?

Back

The simplest form of carbohydrates, consisting of a single sugar molecule, e.g., glucose.

Front

What is the role of enzymes in chemical reactions?

Back

Enzymes lower the activation energy, increasing the rate of chemical reactions.

Front

What is the difference between polar and nonpolar molecules?

Back

Polar molecules dissolve in water, while nonpolar molecules do not.

Front

What are amino acids?

Back

Building blocks of proteins, consisting of an amino group, a carboxyl group, and a unique side chain.

Front

What is the function of carbohydrates?

Back

Provide energy and structural support in cells.

Front

What are lipids?

Back

Hydrophobic molecules that include fats, oils, and phospholipids, important for energy storage and cell membranes.

Front

What are nucleic acids?

Back

Biomolecules that store and transmit genetic information, including DNA and RNA.

Front

What is the structure of proteins?

Back

Proteins are made of one or more polypeptide chains folded into a specific three-dimensional shape.

Front

What is activation energy?

Back

The minimum energy required for a chemical reaction to occur.
