Q

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

Q

How muscle cells make good use of ADP:

A

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
