Front

What is chitin?

Back

Chitin is a polysaccharide that forms the exoskeleton of arthropods and the cell walls of fungi.

Front

What defines a polar covalent bond?

Back

A polar covalent bond is formed when electrons are shared unequally between two atoms, resulting in a molecule with a partial positive charge on one side and a partial negative charge on the other.

Front

What is hydrolysis?

Back

Hydrolysis is a chemical process that breaks down polymers into monomers by adding water.

Front

What is dehydration synthesis?

Back

Dehydration synthesis is a chemical reaction that combines monomers into polymers by removing water.

Front

What are the four main types of macromolecules?

Back

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

Front

What is the monomer of proteins?

Back

The monomer of proteins is an amino acid.

Front

What role do decomposers play in the ecosystem?

Back

Decomposers break down dead organic matter, recycling nutrients back into the soil.

Front

What is the primary function of carbohydrates?

Back

The primary function of carbohydrates is to provide energy for the body.

Front

What are lipids primarily composed of?

Back

Lipids are primarily composed of carbon and hydrogen atoms, with a higher ratio of these elements compared to carbohydrates.
