Q

give two reasons why oxidative phosphorilation is not 100% effective

A

protons leak across membrane
atp is used moving pyruvate into the mitochondria by active transport

Q

describe respiration of lipids

A

lipids hydrolised into glycerol and fatty acids
glycerol phosphorlated and converted to TP which enters glycolosis
fatty acids broken down into 2 fragments which are converted to Acetyl COA which enters the krebs cycle
