Question

which of the following is True about beta oxidization of fatty acid (true or false)

a* to occur in mammalian cell fatty acids must first be converted to acyl-coa which is then converted to acyl camitine for transport into mitochondria

b*. full oxidization of fatty acid will lead to more reduced electron carries NADH and FADH2 as compared to full oxidization of carbohydrate of the same length

c*. production of acetyl coa from fatty acid includes substrate level phosphorylation step similar to glycolysis

d*. similar to glycolsis of acetylcoa from fatty acid can occur anaerobic condition In mammalian cells

e*. Insulin signaling the leads to increase malonyl-coa concentration will lead to increase production of acetyl-coa in beta oxidization

Answer 1

A) fatty acids must first be converted to fatty acyl co A which will then converted to acylcarnitine and will be transported into MITOCHONDRIa it is true because CARNITINE is a transporter which transport fatty acyl co a by binding and making acylcarnitine .

B)true because in this reaction huge amount of FADH2 AND NADH IS PRODUCED WHICH CARRIES ELECTRONS.

C)false because there is no substarte level phosphorylation like GLYCOLYSIS there is only one step which is associated with direct ATP which is the break down of ATP to charge fatty acid.

D)fatty acid oxidation can't be performed in anaerobic conditions Because. As huge NADH and FADH2 is produced, which needs to b3 Oxidized and oxygen is necessary for that.

E)false , because acetyl co a can be increased but this will be from glycolysis not by Fatty acids oxidation Because insulin lessen the amount of glucose and make triglycerides and thus it inhibit oxidation of Fatty acids.
