AnaerobicRespiration
Question | Answer |
---|---|
What is the net yield of Glycolysis? | 2ATP, 2NADH and 2 pyruvate |
Why does anaerobic respiration take place? | insufficient supply of oxygen |
Why cant the reaction proceed if there is not oxygen present? | NAD carriers are full, cannot take anymore H |
What is pyruvate converted to in anaerobic respiration? | lactate |
Why is pyruvate converted? | so NAD can pick up more H |
What happens when lactate dissolves in cytoplasm | lactic acid is formed lowering the pH |
What does a lower pH result in? | enzymes being inhibited or denatured |
what happens when the oxygen supply becomes sufficient | lactate is converted back to pyruvate. OXYGEN DEBT |
What is creatine | a natural amino acid |
Name the chemical stored in muscles | phosphocreatine |
What is PC hydrolysed to? | creatine + P + energy |
What is the energy and P used in? | synthesis of ATP from ADP and P |
Why is this used. | immediate regeneration of ATP, providing short sharp bursts of energy |
