Fatty acid anabolism

Enzyme A catalyse hydrolysis of bonds between fatty acid and the rest of triacylglycerols . What is enzyme A?

• Carnetin Palmitoyl Transferase 1

• Carnetin Palmitoyl Transferase 2

• Lipase

• Acetyl-CoA

Which of the following lipoprotein has the lowest density?

• LDL

• HDL

• Chylomicron

The hydration reaction in beta oxidation of FA is catalyse by:

• hydroxy acyl-CoA dehydrogenase

• enoyl-CoA hydratase

• acyl-CoA dehydrogenase

• carnitine acylcarnitine translocase

Which enzyme is responsible for the conversion of fatty acyl-CoA to trans-2-enoyl-CoA during beta oxidation?

• Fatty acyl-CoA synthetase

• Enoyl-CoA hydratase

• Acyl-CoA dehydrogenase

• Hydroxy acyl-CoA dehydrogenase

Which of the following statements about lipoproteins is true?

• HDL is known as 'bad cholesterol'

• VLDL is primarily responsible for transporting cholesterol

• LDL carries the highest amount of triglycerides

• Chylomicrons are the largest lipoproteins

What is the primary function of lipoprotein lipase in lipid metabolism?

• To synthesize triglycerides

• To hydrolyze triglycerides into free fatty acids

• To transport cholesterol to tissues

• To convert fatty acids into ketone bodies

During beta-oxidation, which molecule is produced as a byproduct of the conversion of acyl-CoA to enoyl-CoA?

• FADH2

• NADH

• CoA

Which enzyme is responsible for the conversion of trans-2-enoyl-CoA to 3-hydroxyacyl-CoA during beta oxidation?

• Hydroxy acyl-CoA dehydrogenase

• Acyl-CoA dehydrogenase

• Carnitine acylcarnitine translocase

• Enoyl-CoA hydratase

What is the primary role of chylomicrons in lipid metabolism?

• To transport fatty acids from the liver

• To deliver dietary triglycerides to tissues

• To synthesize cholesterol

• To store excess fatty acids

Which of the following statements about fatty acid synthesis is true?

• It occurs primarily in the mitochondria

• It requires NADH as a reducing agent
