What is the primary function of proteins?

Back

Proteins provide structural support and act as enzymes to catalyze metabolic reactions.

Front

What macromolecule serves as genetic material in organisms?

Back

Nucleic acids serve as genetic material in organisms.

Front

What are lipids?

Back

Lipids are a group of macromolecules that include fats, oils, and steroids, and are important for energy storage and cell membrane structure.

Front

What are carbohydrates?

Back

Carbohydrates are macromolecules made of sugar molecules that provide energy and structural support in cells.

Front

What are nucleotides?

Back

Nucleotides are the building blocks of nucleic acids, consisting of a sugar, a phosphate group, and a nitrogenous base.

Front

What is the role of enzymes?

Back

Enzymes are proteins that speed up chemical reactions in the body by lowering the activation energy required.

Front

What are amino acids?

Back

Amino acids are the building blocks of proteins, and there are 20 different types that combine in various sequences to form proteins.

Front

What is the structure of a lipid?

Back

Lipids typically have a hydrophobic tail and a hydrophilic head, allowing them to form cell membranes.

Front

What is a polysaccharide?

Back

Polysaccharides are long chains of monosaccharides (simple sugars) that serve as energy storage (like starch) or structural components (like cellulose).
