What’s they key diff?

Answer 2

-

Question 3

Complete the sentence: the longer you exercise…..

Answer 3

-

Question 4

What ways has muscle of regenerating ATP from ADP in anaerobic and aerobic respectively?

Answer 4

-

Question 5

1 Ways muscle regenerates ATP in anaerobic exercise: Phosphocreatine

1. How do you describe it?
2. How much per g of muscle?
3. What kind of compound is this?
4. What transfers to ADP to make ATP?
5. What enzyme does this?
6. What can you say about the recovery?

Answer 5

-

Question 6

2 Ways muscle regenerates ATP in anaerobic exercise: Glycogen

1. How would you describe it?
2. Mobilised to what by what?
3. What is this then converted to by what?
4. And this is the ___ for anaerobic glycolysis
5. What enzyme does the liver have that converts the glucose-6-phosphate to glucose so it can travel in blood?
6. What are the two enzymes that free up glycogen (glycogen phosphorylase and…..)
7. Describe the reaction pathway for this whole scheme and what is added at each stage
   - what causes fatigue?

Answer 6

-

Question 7

Regulation of glycolysis in exercising muscle:

1. Glycogen mobilisation is stimulated by what two things?
2. Phosphofructokinase’s activity increases by what two allosteric regulators? So what does this do>

Answer 7

-

Question 8

How muscle cells make good use of ADP:

Answer 8

ADP increases (because turning ATP into ADP) so adenylate kinase (myokinase) picks it up and converts it to ATP and AMP. AMP makes phosphofructokinase go faster.

Do this when not making ATP fast enough from SLP

Question 9

Aerobic generation of ATP by oxidation of glucose and fatty acids

1. What two things does blood supply?
2. Draw the pathway in your mind plz
3. Now, last 10s of sprint - what happens with glycogen and that pathway?

Answer 9

0

Question 10

Carnitine - does it or does it not help with fat metabolism?

Answer 10

-

Question 11

Aerobically trained - tell me about their reliance on this ‘glycogen top-up’

Also tell me if you have a diet with more glycogen

Answer 11

-

Question 12

What’s the difference between the quadriceps of a marathon runner vs high jumper in terms of their fibres

What were the images stained for?

Answer 12

-
