Question

Are you graduating in December 201 YES/NO 1) Which enzyme is needed for the oxidation of odd-chain saturated fatty acids that is not needed 1) for even-chain fatty acids? A) methylmalonyl-CoA mutase C) methylmalonyl-CoA racemase B) D) All of the above 2) When red-blood cells are treated extensively with protease most down into small peptides. However, some proteins are very resistant to this treatment. 1f cleavage by protease is the only type of reaction that occurs in this treatment, how is this explained? membrane proteins are broken 2) A) They are integral (intrinsic) membrane proteins. B) They contain at least 2 disulfide bonds. C) They are peripheral proteins. D) They are lipid-anchored membrane proteins. 3) The Michaelis constant, Km, is equal to the A) maximum velocity that any given enzyme reaction can achieve B) substrate concentration which gives the best enzyme assay for an enzyme reaction C) maximum velocity divided by two D) substrate concentration when the rate is equal to half its maximal value 4) If an amino acid is glucogenic, it will not be degraded to A) fumarate B) pyruvate C) glutamate D) acetoacetate 5) In mammals, ureogenesis occurs almost exclusively in the A) lining of the small intestine C) pancreas B) kidney D) liver stimulate the conversion of triacylglycerols stored i adipose cells to free fatty acids and monoacylglycerols to provide energy when carbohydrat 6) Elevated levels of the hormone- stores are depleted.

A) To transport fatty acids into the mitochondrion. B) To carry cholesterol from its site of synthesis in the endoplasmic reticulum to t membrane C) To transport newly synthesized sphingolipids to the blood. ha nesembly of chylomicrons.

Answer 1

I will be providing answers of first four questions. Rest of the questions will be answered by other experts.

1)D)

• End products of odd chain saturated fatty acids produce propionyl coA and acetyl coA .

2)A)

• Since, integral membrane proteins are embedded firmly in phospholipid bilayer, they are resistant to the treatment.

3)D)

• It is also used to measure the binding affinity of the substrate with the enzyme.

4)D)

• Glucogenic amino acid is that type of amino acid which can be converted into glucose.
• Only ketogenic amino acids can be degraded to acetoacetate which is a ketone body.
