AP Biology Unit 1 Review

Front

What is hydrolysis?

Back

Hydrolysis is the chemical process of breaking down a polymer by adding water, resulting in the separation of its monomers.

Front

Which macromolecule contains sulfur?

Back

Proteins are the macromolecules that contain sulfur.

Front

Which macromolecules contain nitrogen?

Back

Nucleic Acids and Proteins are the macromolecules that contain nitrogen.

Front

What macromolecule makes up the cell membrane's lining?

Back

Phospholipids make up the cell membrane's lining.

Front

What is the reason large bodies of water do not quickly fluctuate in temperature?

Back

Water has a high heat capacity, which allows it to absorb and retain heat without significant temperature changes.

Front

Define dehydration synthesis.

Back

Dehydration synthesis is a chemical reaction that involves the formation of a bond between two molecules with the removal of water.

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 function of carbohydrates?

Back

The primary function of carbohydrates is to provide energy and structural support in cells.

Front

What role do enzymes play in biological reactions?

Back

Enzymes act as catalysts that speed up chemical reactions by lowering the activation energy required.

Front

What is the structure of a phospholipid?

Back

A phospholipid consists of a hydrophilic (water-attracting) 'head' and two hydrophobic (water-repelling) 'tails'.
