Question

Incorrect Question 2 0/1 pts The mechanism by which insulin decreases oxidation of fatty acids is: O Inhibition of malonyl CoA synthesis O Activation of acetyl CoA carboxylase O Dephosphorylation of carnitine acyl transferase O Dephosphorylation of ACCOA Partial Question 3 1/3 pts Select all the ways in which beta oxidation of fatty acids is regulated Phosphorylation/dephosphorylation of enyzmes Allosterically by ADP Allosterically by NADH Allosterically by ACCOA
Please help me with these questions. I got part of it right not sure about the rest

Answer 1

2. Activation of Acetyl coA carboxylase
When insulin concentration increase in the cell means there is more number of glucose are present in cell. So to decrease the glucose concentration or convert the glucose into fatty acid which activates the
Acetyl coA carboxylase which converts acetyl coA formation in glycolysis is moves to malonyl coA for fatty acid synthesis.

3. Allosterically by NADH and Allosterically by ACCOA
Beta oxidation is allosterically regulated by the ratio of NADH/NAD+ and acetyl-CoA/CoA level.

4. It will utilize more acetyl coA and It will produce excess fatty acid
Acetyl CoA carboxylase is inhibited by phosphorylation by PKA. If it is not phosphorylated it will
continuously active and produces lot of fatty acid.

5. Acetyl coA carboxylase
It is the main regulated enzyme during fatty acid synthesis which is used to produce malonyl coA
by using acetyl CoA.
