What are the two components of a Lipid (Triglyceride) after hydrolysis?
1 Glycerol 3 Fatty Acids
Where and how does Glycerol enter the respiration pathway?
glycerol phosphorylated and converted to triose phosphate enters glycolysis pathway to be converted to pyruvate to move to link
How do Fatty Acids enter respiration?
They are broken into acetate in matrix through beta oxidation acetate then combined with CoA to form acetyl CoA which enters krebs cycle
Why do Lipids produce more ATP per gram than Carbohydrates?
lipids have higher proportion of C-H bonds than carbs during krebs theese bonds broken down to reduce more NAD +FAD more protons and electrons to ETC - steeper electrochem gradient more ATP synthesis via chemiosmosi
whats the step by step of lipid respiration
1 - triglycerideas broken down to glycerol and fatty acids via hydrolysis 2 - glycerol converted to TP in glycolysis 3 - splits into acetate - acetyl CoA - krebs cycle 4 - fatty acid hydrocarbon tails produce massive amount of FADH/NADH 5 - massive electrochemical graident
why is more oxygen needed for respiration of oxygen compared to carbs
lipids have lower O:H ratio so needs more external oxygen as final Electrical Acceptor
where in cell does beta oxidation of fatty acids occur
mitochondrial matrix
where does glycerol enter
glycolysis as TP
where does fatty acids enter
krebs cycle as acetyl coA
