• Tissue

• Cell

• Organism

Which of the following is NOT a structure found in all types of cells?

• Nucleus

• Cell membrane

• Cytoplasm

• Mitochondria

How does a prokaryotic cell differ from a eukaryotic cell?

• Eukaryotic cells have a nucleus, while prokaryotic cells do not.

• Prokaryotic cells are larger than eukaryotic cells.

• Eukaryotic cells lack a cell membrane.

• Prokaryotic cells contain multiple chromosomes.

What is the primary function of a cell’s plasma membrane?

• To generate energy

• To store genetic information

• To regulate the movement of substances in and out of the cell

• To synthesize proteins

Which of the following is NOT one of the four main macromolecules found in the human body?

• Proteins

• Nucleic acids

• Lipids

• Glycogen

Which function is associated with carbohydrates in the human body?

• Insulation and protection

• Speeding up chemical reactions

• Providing energy and structural support

• Carrying genetic information

What occurs during anabolic reactions?

• Molecules are broken down into smaller units.

• Energy is released as heat.

• Smaller molecules are assembled into larger ones.

• Water molecules are removed to form bonds.

What is a key difference between hydrolysis and dehydration synthesis reactions?

• Hydrolysis forms water, while dehydration synthesis uses up water.

• Hydrolysis uses up water, while dehydration synthesis forms water.

• Hydrolysis breaks bonds, while dehydration synthesis makes bonds.

• Hydrolysis releases energy, while dehydration synthesis requires energy.

What process breaks macromolecules into monomers in the food you eat?

• Oxidation

• Condensation

• Hydrolysis

• Fermentation

What is the process called that uses monomers from food to build macromolecules?

• Catabolism

• Metabolism

• Anabolism

• Photosynthesis
