The lactic acid system Flashcards
what is another name for the lactic acid system?
anaerobic glycolysis
where does this process take place?
sarcoplasm
what does this process involve?
particial breakdown of glucose (food)
when can glucose be fully broken down?
when o2 is present
what is the purpose of the lactic acid system?
break down of glucose
why does glucose store more energy?
more complicated compound that pc, therefore stores more energy between its bonds
what is the symbol equation for glucose?
C6H12O6
what is the enzyme that breaks down this glucose?
Glycogen phosphorylase
how is the glucose broken down?
anaerobically
what other enzyme splits the other half of the molecule?
phosphofructokinase
what is phosphofructokinase activated by?
decrease in pc
increase in calcium (secreted during muscle contraction)
what is glucose broken down to?
pyruvic acid
What happens when pyruvate acid is broken down?
Energy and Lactic acid is released
Where does energy from the Lactic acid system go?
Breakdown of glucose bonds anaerobically releases enough energy re-sythesised 2 molecules of ATP
What is a weakness of this process?
The system takes longer than ATP-PC as there are more bonds to break, but still a very quick process
