What is the fate of lactate following exercise cessation?

		Rapid removal in urine since lactic acid is harmful to thebody
		Converted to glucose/glycogen by the Cori cycle

Question 30

Which of the following will decrease the most—as a percentage ofits resting concentration--during an all-out 100-meter dash(lasting about 10 seconds)?

	A.	Blood glucose concentration
	B.	Muscle glycogen concentration
	C.	Muscle ATP concentration
	D.	Muscle CP concentration

Question 31

What would the effects of a month long high-protein, high-fatdiet, low carbohydrate diet be on athletic performance during amarathon? Assume that the person will run the majority of themarathon at >80% VO2peak and will likely run the last few milesat 90% VO2peak:

	A.	Improve because you have now trained the body to oxidize fattyacids for prolonged periods of time
	B.	Improved performance because it provides plenty of protein /amino acids for prolonged exercise which can be used forgluconeogenesis
	C.	The subject will be glycogen depleted and performance will beworse
	D.	No effect

Question 32

A person accidentally ingests a substance that renders themitochondrial electron transport chain non-functional. Thefollowing is true:

	A.	Nothing will change since NADH and FADH are produced duringß-oxidation and the Krebs cycle prior to entering the ETC
	B.	The Kreb’s cycle will speed up to compensate
	C.	The individual will switch to protein breakdown to meet ATPneeds
	D.	Cellular respiration will be severely compromised

Question 33

You are training a 400-meter running athlete who states she istaking a supplement to increase the bioavailability and activity ofphosphoglucoisomerase (a glycolysis pathway enzyme) to boost herrace performance. What is the effect you expect?

	A.	Some improvement since the rate of anaerobic glycolysis willincrease
	B.	Worse performance because the levels of enzymes are finely tunedand the disequilibrium from the supplement will affect glycolyticactivity
	C.	No change
	D.	Not enough information
