Biology EOC Review #1

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.

• metabolism

• homeostasis

• synthesis

A strand of DNA has these bases:

AGC CAT GTA TAC

What is the complementary DNA strand?

• ACG GAT CTA TAG

• TCG GTA CAT ATG

• TGC CTA GAT ATC

• UCG CUA CAU AUG

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

• 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.

• Cells contain DNA, which controls the production of proteins.

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 less energy.

• Aerobic respiration results in more energy.

• Each process results in equal amounts of energy.

• Each process results in variable amounts of energy.
