Question 14
Which of the following reactions will result in the most ATP production?
A.
Breakdown of 30 mols of creatine phosphate (CP)
B.
Complete oxidation of 5.0 mols pyruvic acid or pyruvate
C.
Oxidation of 10 mols of NADH + H+
D.
Breakdown of 2 mols of glucose to 4 mols of lactic acid
Question 18
The process that forms new glucose in the liver is called ...
A.
glycogenolysis
B.
Krebs cycle
C.
lipolysis
D.
gluconeogenisis
E.
oxidative phosphorylation
Question 24
What is the fate of lactate following exercise cessation?
Rapid removal in urine since lactic acid is harmful to the body
Converted to glucose/glycogen by the Cori cycle
Rapid lactate detoxification by the liver
Lactate is oxidized and used as a substrate and a percentage of it is used to regenerate glucose stores via the Cori cycle
Question 34
Which of the following metabolic pathways generates the most ATP if it is only taking place once?
A.
the ATP – PC pathway
B.
anaerobic glycolysis
C.
anaerobic glycolysis combined with the electron transport system
(skipping the Krebs cycle)
D.
beta oxidation combined with the electron transport system
(skipping the Krebs cycle)
Question 35
Which of the following statements is true concerning homeostasis?
A.
The terms steady state and homeostasis refer to the same thing; therefore a homeostasis could be attained during exercise.
B.
A true homeostasis is not attained during exercise; however a steady state may be attained with exercise.
C.
If I were shivering (from cold temperatures); I could still be in homeostasis.
D.
If I am in a steady state, I am automatically in homeostasis
E.
None of the above are true
A.
Breakdown of 30 mols of creatine phosphate (CP)
B.
Complete oxidation of 5.0 mols pyruvic acid or pyruvate
C.
Oxidation of 10 mols of NADH + H+
D.
Breakdown of 2 mols of glucose to 4 mols of lactic acid
Explanation / Answer
1.ans is A .
1 mol of CP produce 10 ATP..
30 mol produce 300 atp.
5mol of pyruvuc acid produce 125 atp.
10 mol of nadh produce 25 atp.
2 mol of glucose to lactic acid produce 18 atp.
18.gluconeogenesis is synthesis if new glucose.
Lipolysis is breakdown of lipid .
Glycogenlysis is breakdown of glycogen
Tca cycle also konwn as krebs cycle.
24 after excercise cessastion lactate convetred to glucose or glycogen by cori 's cycle.
