Front

What are monomers?

Back

Monomers are the basic building blocks of macromolecules. Examples include monosaccharides, fatty acids, amino acids, and nucleotides.

Front

What is the secondary structure of proteins?

Back

The secondary structure of proteins refers to the local folded structures that form within a polypeptide due to hydrogen bonding between backbone atoms. Common examples include alpha helices and beta sheets.

Front

What are the monomers that make up lipids?

Back

The monomers that make up lipids are glycerols and fatty acids.

Front

What type of macromolecule is formed by polymerized glucose molecules?

Back

The macromolecule formed by polymerized glucose molecules is a carbohydrate.

Front

What is cohesion in the context of water?

Back

Cohesion is the tendency of water molecules to 'stick' to each other due to hydrogen bonding.

Front

What are the four main types of macromolecules?

Back

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

Front

What is the primary structure of proteins?

Back

The primary structure of proteins is the unique sequence of amino acids in a polypeptide chain.

Front

What is a polymer?

Back

A polymer is a large molecule composed of repeating structural units (monomers) connected by covalent bonds.

Front

What is the role of enzymes in biological reactions?

Back

Enzymes are biological catalysts that speed up chemical reactions by lowering the activation energy.

Front

What is the difference between saturated and unsaturated fats?

Back

Saturated fats have no double bonds between carbon atoms, while unsaturated fats contain one or more double bonds.
