• a polysaccharide, and the complex carbohydrate could be a protein molecule.

• an amino acid, and the complex carbohydrate is a fat molecule.

• a fatty acid, and the complex carbohydrate is a protein molecule.

Based on the table, the molecules in the bread are broken down into smaller molecules at W called

• simple sugars.

• fatty acids.

• polysaccharides.

• lipids.

The picture shows the nutritional label for Greek yogurt, a milk-based food product that is high in protein. When a person eats the yogurt, the 14 grams of protein will be

• combined into monosaccharides.

• combined into polysaccharides.

• broken down into amino acids.

• broken down into nucleic acids.

Which of the following describes monosaccharides?

• Monosaccharides are responsible for lowering the activation energy of biochemical reactions.

• Monosaccharides are simple proteins composed of carbon, nitrogen, and hydrogen.

• Monosaccharides are the main molecules used as fuel for cellular work.

• Monosaccharides are polymers that are broken down into simpler monomers.

The cell membrane is mainly made up of lipids and proteins. It acts as a barrier to the surrounding environment. Which of the following statements about lipids BEST supports the argument that lipids help protect the contents of the cell?

• Lipids that are placed in water do not dissolve.

• The tail of a lipid is made of carbon and hydrogen.

• Individual lipids in a membrane can rotate freely.

• Lipids are composed of a head and a thin tail.

Which of the following tables best matches each major macromolecule with its appropriate function?

• A.

• B.

• C.

Which statement best describes what enzymes do?

• A. They influence the rate of chemical reactions.

• B. They become the building blocks of polymers.

• C. They maintain a steady rate of breathing.

• D. They speed up the conduction of nerve impulses.

Enzymes are sensitive to pH and temperature. If an enzyme's environment is too hot, the enzyme cannot:

• develop flagella and move closer to a substrate.

• transform into a sugar that causes a reaction in a substrate.

• bind to a substrate and cause a reaction in the substrate.

• stimulate other molecules to become substrates.
