The bonds between substrates are broken.

Which word equation best represents the process of cellular respiration?

glucose + oxygen → carbon dioxide + water

carbon dioxide + glucose → oxygen + water

carbon dioxide + water → glucose + oxygen

oxygen + water → carbon dioxide + glucose

How does the body of a runner keep up with the demand for energy when cellular oxygen levels are low?

through anaerobic respiration in the cytoplasm

through energy production in the mitochondria

through aerobic respiration in the plasma membrane

through ATP produced directly from sunlight

What will most likely be the result if all of the mitochondria are removed from a plant cell?

It will be unable to carry out respiration.

It will lose water through osmosis.

It will break down the ribosomes in the cell.

It will be unable to photosynthesize.

Which statement best describes the relationship that exists among proteins, DNA, and cells?

Cells contain DNA, which controls the production of proteins.

Proteins combine to produce cells, which produce DNA.

Proteins are made up of DNA, which determines the cells that are produced.

DNA is made up of proteins, which tell a cell how to function.

What are the subunits of DNA and their function?

nucleotides that store information

monosaccharides that provide quick energy for the cell

lipids that store energy and provide insulation

proteins that provide the building blocks for the structural components of organisms

How does the amount of energy resulting from fermentation compare with that of aerobic respiration?

Aerobic respiration results in more energy.

Aerobic respiration results in less energy.

Each process results in equal amounts of energy.

Each process results in variable amounts of energy.

How does DNA code for proteins in a cell?

by arranging certain nitrogen bases of the cell in a particular order

by creating a new double helix structure

by using its phosphate and sugar molecules

by adding more hydrogen bonds to its structure

Which factor most affects the order of amino acids in a protein?

the DNA located in the nucleus of the cell

the cell in which the protein is located

the amount of ATP available for the cell’s use

the area in a cell where proteins are produced

Which statement best compares aerobic and anaerobic respiration?

Less ATP is generated during anaerobic respiration than during aerobic respiration.

More water is generated during anaerobic respiration than during aerobic respiration.

More oxygen is generated during anaerobic respiration than during aerobic respiration.

Less lactic acid is generated during anaerobic respiration than during aerobic respiration.

Which would be the best evidence that a cell is using active transport to move a substance across its cell membrane?

ATP is being rapidly consumed near the cellular membrane.

Substances are moving rapidly across the cell membrane.

Substances are moving from high to low concentrations.

Substances are moving through channels in the cell membrane.

Which best describes the role of translation in helping cells code for proteins?

The bases in messenger RNA code for the sequence of amino acids in proteins.

The bases in transfer RNA code for the sequence of amino acids in proteins.

The nucleotides in RNA and DNA determine the sequence of amino acids in proteins.

The bases in ribosomal RNA code for the sequence of amino acids in proteins.

Which causes plants to produce more oxygen on sunny days?

There is more energy for photosynthesis

There is more water available for transpiration.

There is more carbon dioxide for respiration.

There is more chlorophyll for fermentation.
