Respiration

Anaerobic respiration
-
this means that oxygen isn't present to accept the electrons at the end of the electron transport chain, so no further ATP is made in oxidative phosphorylation
this means that since the electrons remain in the transport chain, there are no free carriers to accept the hydrogens from NADH and FADH so they stay reduced

lactate fermentation
-
lactate can be oxidised back to pyruvate, which can be fed into the Krebs cycle to make ATP, but this requires oxygen (called oxygen debt)
lactate can also be converted into glycogen and stored, which happens in the liver in mammals
Glycolysis
-
-
-
step 1: phosphorylation
2 molecules of ATP each donate a phosphate to glucose, forming fructose 1,6 bisphosphate (6 carbons)
fructose 1,6 bisphosphate splits into 2 molecules of triose phosphate (3 carbons)
step 2: Redox
1 hydrogen from each of the triose phosphate molecules is removed and added to NAD to form 2 molecules of NADH
-
4 molecules of ATP are formed from the direct transfer of phosphate groups from the phosphorylated intermediates to ADP (substrate linked phosphorylation)
