Question 1 of 16

1

Which of the following best examples why aerobic respiration is more energy efficient than anaerobic respiration?

Select one of the following:

  • Aerobic respiration occurs in one step, while anaerobic respiration requires several steps .

  • Aerobic respiration produces less CO2 per molecule of glucose .

  • Aerobic respiration produces more ATP per molecule of glucose.

  • Aerobic respiration fully breaks down glucose, while anaerobic respiration does not.

Explanation

1

A student adds a suspension of bakers yeast cells into bread dough. When this mixture is left Ina large bowl undisturbed for several hours, the student returns to find that the bread dough has doubled in size. What gas molecule is responsible for this increase in dough size?

Select one of the following:

  • H²

  • N²

  • CO²

Explanation

Question 9 of 16

1

Which of the following are products of aeroblic respiration?

Select one of the following:

  • Carbon dioxide and water

  • Carbon dioxide and oxygen

  • Glucose and water

  • Glucose and oxygen

Explanation

Question 10 of 16

1

Which of the following statements about araebic respiration is correct?

Select one of the following:

  • It produces ethenol

  • It only takes place in plants

  • It only takes place In prokaryotes

  • It requires oxygen

Explanation

Question 11 of 16

1

Organisms undergo many different processes on order to be able to store energy and utilize that energy. Through which of the following processes is energy released in the form of ATP?,

Select one of the following:

  • Phototropism

  • Cellular respiration

  • Endocytosis

  • photosynthesis

Explanation

Question 12 of 16

1

A scienstist is studying the reapiration reactions carried out by a certain bacterium. Which of these would indicate that the respiration reactions occurring are anaerobic?

Select one of the following:

  • Glucose is consumed

  • Oxygen is consumed

  • Carbon dioxide is produced

  • Ethanol is produced

Explanation

Question 13 of 16

1

During periods of intense exercise, cells do not receive enough oxygen to perform the normal process of aerobic cellular respiration. As a result, the cells resort to anaerobic respiration, which produces only 1/20th of the energy produced during the aerobic process. This alternative version of cellular respiration produces lactic acid as waste, which results in muscle soreness.
Which of the following statements does the above info support?

Select one of the following:

  • Cellular respiration in affected by the availability of reactants

  • Cellular respiration in affected by temperature

  • Cellular respiration in affected by sugar production

  • Cellular respiration in affected by cell hydration

Explanation

Question 14 of 16

1

Which of the following are reactants in the process of aerobic respiration?

Select one of the following:

  • Carbon dioxide and water

  • Glucose and water

  • Carbon dioxide and oxygen

  • Glucose and oxygen

Explanation

Question 15 of 16

1

Lactic acid fermentation in bacteria can be used to make which of the following foods?

Select one of the following:

  • Beer and bread

  • Yogurt and sauerkraut

  • Sauerkraut and beer

  • Bread and yogurt

Explanation

Question 16 of 16

1

Which of the following is a final product of aerobic respiration?

Select one of the following:

  • Pyruvate

  • Glucose

  • Carbon dioxide

  • Oxygen
