Questions and Answers

What is the purpose of venepuncture?

  • To measure relative abundance in large muscle volumes
  • To measure single fibre metabolite concentrations
  • To collect discrete samples (correct)
  • To prevent accumulation of AMP

What is the main difference between collecting plasma and serum?

  • Serum is collected using venepuncture but plasma is collected using cannulation
  • Plasma is used to measure single fibre metabolite concentrations but serum is used for large muscle volumes
  • Plasma allows blood to clot at room temperature but serum does not
  • Anticoagulant is added to blood for plasma but not for serum (correct)

Where is LDH-M found?

  • At the Na/K and Ca pumps
  • Type I muscle fibres
  • On allosteric inhibitory sites
  • Type II muscle fibres (correct)
