NUTR Exam - Accurate Solutions For Every
Question
What is the primary function of cellular respiration? Correct
Answer - to regenerate ATP
Cellular respiration takes energy from our food nutrients and
transfers that energy into a usable form of energy in ATP.
Catabolism would be best described as a process that ________.
Correct Answer - breaks down complex structures to simpler
ones
Which nutrients function primarily as an energy source for cells?
Correct Answer - Carbohydrates are needed in relatively large
amounts to supply glucose, the main energy source for body cells.
Which term describes the action of an endurance runner the night
before the race as she "carbo-loads" when eating a large pasta
dinner? Correct Answer - glycogenesis
Heavy sweating can induce heat cramps due to ______.
A) abnormal electrolyte levels in muscle cells
B) abnormal electrolyte levels in neurons
C) abnormal electrolyte levels in interstitial fluid
D) All of the listed responses are correct. Correct Answer - All
of the listed responses are correct.
Use your textbook to review the mechanisms of heat exchange in the
body.
, n the case of a person who consumes a normal, balanced diet,
proteins are essential to the body for all of the following EXCEPT
________.
A) production of enzymes, clotting factors, and antibodies
B) production of energy
C) production of some hormones
D) formation of functional molecules like hemoglobin and
cytochromes Correct Answer - production of energy
Which of the following is correct?
A) Each FADH2 yields about 1.5 ATP via oxidative phosphorylation.
B) Glycolysis relies on substrate-level oxidation for the four ATP
produced in this pathway.
C) Most of the ATP are produced by substrate-level phosphorylation.
D) Most ATP from cellular respiration are produced directly in the
citric acid (Krebs) cycle. Correct Answer - Each FADH2 yields
about 1.5 ATP via oxidative phosphorylation.
Which of the following is a common feature of both sets of reactions
represented by A and B in the figure? Correct Answer - Both
include steps involving the oxidation of organic molecules.
Both glycolysis (A) and the citric acid cycle (B) involve the stepwise
breakdown of food molecules by a series of oxidation reactions.
Which of the following mechanisms produces the most ATP during
cellular respiration? Correct Answer - oxidative
phosphorylation
While traveling abroad in Africa you observe a large number of
people with goiter (enlarged thyroid). Which mineral deficiency
could be responsible for this? Correct Answer - iodine
