Biology 105 -Multiple choice quiz - Metabolism
Choose the correct answer for each question.
1
It is possible to determine the approximate ratio of fat to carbohydrate use in a human by:
Monitoring urine urea concentration.
Measuring respiratory oxygen utilization and carbon dioxide production.
Determining the percentage of convective blood flow.
Measuring blood glucose level
A and B.
2
Adenosine triphosphate (ATP)
Is formed by the condensation synthesis of glucose and maltose.
Can be formed in a single reaction from adenosine diphosphate and phosphocreatine.
Is made from the amino acid adenosine and two phosphate molecules.
Can be produced from aerobic but not anaerobic metabolism.
None of the above.
3
During high intensity, short-duration (15 seconds) exercise,
Fat is a primary fuel source because glycogen sparing is important.
Anaerobic metabolism of fat is an important fuel source.
The phosphagen system is a primary source of energy.
B and C.
A, B, and C.
4
During a marathon (26.2 mile) run, aerobic metabolism predominates over anaerobic metabolism because:
More power is produced using aerobic metabolism than anaerobic metabolism.
Fat stores are expended during the first few minutes of exercise
Aerobic metabolism uses glucose very efficiently compared to anaerobic metabolism.
Aerobic metabolism produces lactic acid.
None of the above
5
Glycogen is an excellent fuel storage molecule because:
Glycogen is more energy-dense than lipids.
Less water is stored with glycogen than glucose.
Glycogen can be broken down to simple sugars which can then be used for aerobic or anaerobic respiration.
B and C.
A, B, and C.
