Question

question 25
the cori cycle occurs in the liver.
true
false
question 26
the major characteristics of the oxygen system include:
high atp production
fast atp utilization
ability to remove lactic acid
all of the above
a and b only
question 27
all energy in the human body is derived from the breakdown of complex nutrients like carbohydrates, fats, and proteins.
true
false

Explanation:

• Question 25: The Cori - cycle involves the conversion of lactate produced in muscles to glucose in the liver. So the statement "The Cori cycle occurs in the liver" is false since it also involves muscles.
• Question 26: The oxygen system (aerobic energy system) has high ATP production through oxidative phosphorylation, fast ATP utilization as it can sustain energy - demanding activities for long periods, and the ability to remove lactic acid by oxidizing it. So all the given characteristics are correct.
• Question 27: The human body derives energy from the breakdown of carbohydrates, fats, and proteins through metabolic processes like glycolysis, beta - oxidation, and proteolysis. This statement is true.

Answer:

Question 25: B. False
Question 26: D. all of the above
Question 27: A. True
