B) Nutrient storage and tissue building
C) Muscle atrophy
D) Protein oxidation
B
What role does insulin play in muscle health?
A) It increases muscle breakdown.
B) It prevents muscle breakdown.
C) It has no impact on muscle tissue.
D) It stimulates muscle atrophy.
B
Which hormones are known to increase muscle hypertrophy?
A) Cortisol and insulin
B) Growth hormone and cortisol
C) Insulin and testosterone
D) Growth hormone and testosterone
D
What does a negative nitrogen balance indicate about a person’s protein status?
A) Protein intake is balanced with protein excretion.
B) Protein intake is less than protein excretion.
C) Protein intake is greater than protein excretion.
D) The individual is consuming too much protein.
B
Which is the primary purpose of the Recommended Dietary Allowance (RDA) for protein?
A) To ensure maximal physical performance
B) To prevent protein deficiency and associated diseases
C) To optimize muscle hypertrophy
D) To reduce protein intake to safe levels
B
What is the primary method used to assess nitrogen balance?
A) By measuring protein levels in the blood
B) Through dietary recall and estimation
C) By collecting and analyzing excreted nitrogen in urine, feces, and sweat
D) By observing physical symptoms of protein deficiency
C
What are some challenges associated with the nitrogen balance technique?
A) It is an inexpensive and quick process.
B) It often underestimates the true protein requirements.
C) It requires minimal participant compliance.
D) It always provides an accurate measure of protein needs.
B
How does the IAAO method indicate protein sufficiency?
A) When the labeled amino acid is mostly excreted in urine.
B) When the labeled amino acid is detected less in breath CO2 as protein intake increases.
C) When the labeled amino acid causes an increase in muscle mass.
D) When the labeled amino acid shows no change in oxidation levels.
B
What does the ‘break point’ in the IAAO graph signify?
A) The maximum safe level of protein intake.
B) The minimum protein requirement to prevent disease.
C) The protein requirement of an individual.
D) The point where protein intake has no further health benefits.
D
Which factor contributes to muscle atrophy?
A) Anabolic hormone activity
B) Increased testosterone production
C) Cortisol activity under stress
D) High protein intake
