and answers 2025/2026.
______________ are enzymes that transfer the primary amine of amino acids to a-keto acids to
form Glu, Asp, Ala, or Gin for transport from tissues to liver.
A) amino peptidases
B) amino oxidases
C) aminotransferases
D) transaminases
E) C and D - correct answers E) C and D
Accumulation of uric acid crystals in joints due to defective uric acid metabolism in humans
causes _____________. - correct answers gout
Acetoacetate and ____________ are referred to as ketone bodies and are a major fuel source
for muscle tissue during fasts and starvation
A) pyruvate
B) acetone
C) beta-hydroxybutyrate
D) gamma butyric acid
E) B and C - correct answers E) B and C
Activated acyl CoA molecules are transported across the mitochondrial inner membrane as a(n):
A) acyl CoA
B) acetyl-CoA
, C) carnitine CoA
D) acyl carnitine
E) none of the above - correct answers D) acyl carnitine
Beta-oxidation of odd-numbered fatty acids produces acetyl CoA and
_______________________. - correct answers propionyl CoA
Briefly outline the steps in degradation of triacylglycerides to acetyl CoA. - correct answers
Triacylglycerides are first broken down into fatty acids. The fatty acids are then activated in the
form of acyl CoA by the enzyme fatty acyl-CoA synthetase so that they can enter the
mitochondria. Acyl CoA is then conjugated to carnitine and is able to be transported into the
mitochondria where the acyl carnitine is converted back into acyl CoA. Once the fatty acids are
inside the mitochondria, they undergo beta-oxidation into 2-carbon acetyl CoA units.
Coenzyme(s) involved in the degradation of saturated fatty acyl CoA include(s):
A) FAD
B) NAD+
C) TPP
D) A and B
E) A, B and C - correct answers D) A and B
Conversion of glucose 1-phosphate to glucose 6-phosphate is carried out by the enzyme:
A) phosphoglucomutase
B) kinase 1-P
C) phosphoglycerate mutase
D) all of the above
E) none of the above - correct answers A) phosphoglucomutase
