Question
1. What is the energy requirement for the conversion of a fatty acid to a thioester with coenzyme A in the ?-oxidation of a fatty acid?
This process requires energy.
This process is energy neutral – energy is neither required nor released.
This process releases energy.
Whether energy is required or released depends on the identity of the fatty acid being oxidized.
2.
Which is the enzyme that hydrolyzes triacylglycerols?
acetyl CoA
protease pepsin
amylase
lipase
succinate dehydrogenase
a.This process requires energy.
b.This process is energy neutral – energy is neither required nor released.
c.This process releases energy.
d.Whether energy is required or released depends on the identity of the fatty acid being oxidized.
Explanation / Answer
Conversion of fatty acid to a thioester with coenzyme A require ATP molecules.
This is a energy requiring process.
Option a is the answer
Hydrolysis of triacylglycerols require enzyme called lipases.
Lipases convert triacylglycerols to glycerol and fatty acids.
Option d is the answer
