Unit 5 Practice Questions

Cellular respiration and photosynthesis are considered to be....

• the same equation

• opposites of one another

• unique in every way

• not important at all!

Which would be the best evidence that a cell is using active transport to move a

substance across its cell membrane?

• Substances are moving rapidly across the cell membrane

• ATP is being rapidly consumed near the cellular membrane

• Substances are moving from high to low concentrations

• Substances are moving through channels in the cell membrane

Yeast and some bacteria can use fermentation of sugars to make ATP. Bakers and brewers can take advantage of the process to make commercial products. What are the products of this form of fermentation?

• alcohol and carbon dioxide

• lactic acid and carbon dioxide

• oxygen and pyruvic acid

• NADH and ATP

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

What is the function of autotrophs in the carbon cycle?

• to use oxygen to produce glucose

• to take in excess water

• to use carbon dioxide to produce glucose

• to feed on herbivores
