Protein Metabolism Flashcards
(12 cards)
Which of the following statements accurately describes the impact of carbohydrate and protein ingestion on muscle protein synthesis (MPS)?
The combination of carbohydrates and protein synergistically enhances MPS compared to either nutrient alone.
Which of the following statements accurately describes myofibrillar protein synthesis following workload-matched versus reps to failure at low (30% 1RM) to heavy (90% 1RM) intensities?
Reps to failure at low intensities result in higher myofibrillar protein synthesis compared to workload-matched scenarios.
The effect of insulin in muscle accretion is predominantly through its action on
Decreasing protein breakdown
Which of the following statements is FALSE with respect to the Glucose-Alanine cycle?
When blood glucose concentrations are high, the use of carbohydrates in the muscle is high
What distinguishes essential amino acids from nonessential amino acids?
Essential amino acids cannot be synthesized by the body and must be consumed in foods, while nonessential amino acids are produced by the body.
Anabolic resistance is NOT characterised by
Increased postprandial amino acid availability
Net muscle protein balance =
Synthesis – breakdown – oxidation
What is the optimal amount of protein to consume post work out?
20g
In a study comparing lean body mass gains after soy versus milk ingestion, which of the following statements is correct?
Milk ingestion resulted in significantly higher lean body mass gains compared to soy.
What is one of the functions of deamination in amino acid metabolism?
To promote gluconeogenesis.
Which of the following statements accurately describes the mTOR signaling pathway and its role in muscle protein synthesis?
mTOR is a kinase involved in nutrient sensing, and its activation stimulates muscle protein synthesis.
Which of the following statements about (in)complete proteins is false
A vegan diet will always result in protein deficiency
