Front

What are complex carbohydrates made of?

Back

Complex carbohydrates are made of long chains of monosaccharides connected by covalent bonds.

Front

What type of macromolecule is protein?

Back

Proteins are macromolecules made up of amino acids, which contain carbon, hydrogen, oxygen, nitrogen, and sometimes sulfur.

Front

What is dehydration synthesis?

Back

Dehydration synthesis is the process by which two monomers join together with a covalent bond, releasing a molecule of water.

Front

What is the effect of lipodystrophy on fat storage?

Back

Lipodystrophy leads to a decrease in fat storage in cells due to the lack of an enzyme required for triglyceride synthesis.

Front

What are the structural forms of carbohydrates?

Back

Carbohydrates can occur as monomers, chains of monomers, and branched structures.

Front

What is a monosaccharide?

Back

A monosaccharide is the simplest form of carbohydrates, consisting of a single sugar molecule, such as glucose.

Front

What is a polysaccharide?

Back

A polysaccharide is a carbohydrate that consists of long chains of monosaccharides linked together, such as starch or glycogen.

Front

What is the role of triglycerides in the body?

Back

Triglycerides serve as an energy reserve in fat cells.

Front

What is the difference between covalent bonds and hydrogen bonds?

Back

Covalent bonds involve the sharing of electron pairs between atoms, while hydrogen bonds are weak attractions between a hydrogen atom and an electronegative atom.

Front

What are the building blocks of proteins?

Back

The building blocks of proteins are amino acids.
