New cards

What stages not present

  1. no final electron acceptor

  2. H ions built up in matrix

  3. no electrochemical gradient

  4. no ATP produced

  5. NADH/FADH2 cannot donate e- to e- transport chain

  6. no reoxidised NAD and FAD

  7. krebs link require NAD FAD so can not occur

  8. only glycolysis can occur

2
New cards

ethanol production process

cytoplasm - glycolysis

pyruvate → ethanal - NADH made→ ethanol

3
New cards

Lactate production process

glucose → pyruvate -(NAD+ made via lactate dehydrogenase) → Lactase (converted back to pyruvate/glycogen)

4
New cards

gluconeogenesis meaning

made into glycogen to replenish muscle stores

5
New cards

issues of lactic acid

  • build up lactic acid and H+ creates acidic environment

  • pH falls

  • affects enzymes (denature)

  • reduced stimulation of muscles from nervous system
