The biochemical function of enzymes is to:

• Hold genetic information.

• Speed up chemical reactions.

• Provide buoyancy.

• Store energy.

• Provide structure.

One important function of carbohydrates is that they:

• Store energy.

• Form enzymes.

• Repel water.

• Hold genetic information.

• Are structural molecules in membranes.

Which of the following organic molecules stores energy, provides insulation, and assists in buoyancy?

• Lipids

• Carbohydrates

• Proteins

• Amino acids

• Nucleic acids

Which of these molecules stores and transmits genetic information?

• Carbohydrates

• Lipids

• Proteins

• Nucleic acids

• Amino acids

One of the by-product results of photosynthesis is:

• Carbon dioxide is released.

• Energy is released into the surrounding environment.

• Oxygen is released.

• Water is produced.

• Energy is contained in the water molecules.

What is the role of ATP in organisms?

• Speeds up chemical reactions and reduces enthalpy

• Serves as a structural molecule for cell walls and membranes

• Serves as a genetic transfer molecule in subsequent generations

• Serves as a genetic storage molecule for storage of genetic mutations

• Serves as an energy storage molecule for direct use by the cell

The term ecosystem best encompasses which one of the following?

• All living organisms living in one area without regards to the physical setting

• The community or communities but not the physical environment

• The community or communities and the physical environment

• Populations in one area but not the physical environment

• Populations and communities living in one area

Bacteriophages are types of:

• Viruses

• Protozoa

• Archaea

• Algae

• Bacteria

Bacteria that make their own organic compounds by obtaining energy from chemical compounds and not directly from light are known as:

• Heterotrophic
