Lecture 1:No questions.
Lecture 2:
Q1: Hexokinase enzyme is:1.Non specific enzyme.
2.Highly specific enzyme.
3.Provide you with 2 ATPs.
4.Provide you with 4 ATPs.
A: 1
Lecture 3:
Q2: An athletic weighting 85 KG having heaving exercising through running for 5 Killo meters. calculate the number of ATPs in the 1.RBCs 2. in the Skeletal muscles. at the beginning of the exercise and at the end of the exercise.A: RBCs at the beginning 2 ATP, at the end 2 ATP.
Skeletal muscles at the beginning 8 ATP, at the end 2 ATP.
Q3: Pentose phosphate pathway is:
1.An essential pathway for all body cells.2.Produce reduced NAD.
3.Essential for fatty acid synthesis.
4.Essential for glycogen formation
A:1
Lecture 4:
Q4: Calculate the number of ATP produced by complete metabolism of 1 glucose molecule in aerobic condition.
A: 38 ATP.
Q5: Calculate the number of ATP obtained in the skeletal muscle from complete metabolism of 1 glucose molecule in the skeletal muscle at resting condition.
A: 38 ATP.
Q6: Calculate the number of ATP obtained from the metabolism of one glucose molecule in the skeletal muscle at a mild exercise.
A: At the beginning is 38 ATP, at the end 2 ATP.
Q7: Calculate the number of ATP obtained from the metabolism of one glucose molecule in the skeletal muscle at a heavy exhausted exercise.
A: 2 ATP.
Lecture 5:
Q8: Calculate the number of ATP lost during the gluconeogenesis starting from pyrovate.A: 6 ATP.
Q9: Calculate the number of ATP lost during gluconeogenesis started from lactate.
A: 6 ATP.
Q10: Calculate the number of ATP gained from complete aerobic metabolism of gluconeogenesis from lactate to glucose and from glucose through aerobic pathway.
A: -6 + 38 = 32 ATP.
Q11: Calculate the number of ATP produce by complete metabolism of glucose in anaerobic pathway in the kidneys.
A: incorrect question because in the kidneys are all aerobic.
So the answer is in the aerobic are 38 ATP.
Lecture 6:
Q12: Liver glycogen is converted in it's metabolism to:
1.Short glycogen molecules.
2.Disaccarides.
3.Polysaccarides.
4.Free glucose.
A: 4
Q13: Glycogen is:
1.Rich chain of glucose molecules.2.Branched chain synthesized in the intestine.
3.Consist of glucose molecules attached together at α-1,4 and α-1,6 molecules.
4.Need glycogen phosphorylase for it's synthesis
A:3
Lecture 7:
Q14: How many glucose molecules can we gain from a lactose molecule of the milk:A:2
Q15:Can hexokinase enzyme convert Galactose to Galactose-1-phosphate?
A:Yes because it's not specific enzyme.
Q16: Discuss the Galactose metabolism in health and in disease (Gactossemia).
Q17: Newly born baby presented with vomiting particularly after taking the milk, this baby might have one of the following enzyme deficiency:
1.Fructose 1-Phosphate aldolase.
2.Glucokinase.
