AP Semester 1 Exam Practice Questions

Front

What is hydrolysis?

Back

Hydrolysis is a chemical process that involves the breaking down of a compound by the addition of water, often resulting in the formation of smaller molecules or monomers.

Front

What role do enzymes play in biochemical reactions?

Back

Enzymes speed up biochemical reactions by lowering the activation energy required for the reaction to occur.

Front

What are saturated fatty acids?

Back

Saturated fatty acids are types of fatty acids that have no double bonds between carbon atoms, making them solid at room temperature and more common in animal fats.

Front

What happens to an animal cell in a hypertonic solution?

Back

An animal cell placed in a hypertonic solution will shrink (get smaller) due to the loss of water.

Front

What is the result of hydrolysis on polymers?

Back

Hydrolysis splits polymers into their monomer units.

Front

Define activation energy.

Back

Activation energy is the minimum amount of energy required to initiate a chemical reaction.

Front

What is dehydration synthesis?

Back

Dehydration synthesis is a chemical reaction that involves the joining of two molecules with the removal of water, often forming polymers from monomers.

Front

What is a disaccharide?

Back

A disaccharide is a carbohydrate composed of two monosaccharides linked together by a glycosidic bond.

Front

Give an example of a disaccharide and its monomers.

Back

Sucrose is a disaccharide made up of glucose and fructose.

Front

What is the difference between saturated and unsaturated fatty acids?

Back

Saturated fatty acids have no double bonds and are typically solid at room temperature, while unsaturated fatty acids have one or more double bonds and are usually liquid at room temperature.
