Question
Chapter 25, Problem 25.52CP
Interpretation Introduction
Interpretation:
Statement “the total energy cost is four ATP in urea cycle” has to be explained.
Concept introduction:
The cyclic biological pathway that produces urea for excretion is called urea cycle.
- Step 1: It include carbamoyl phosphate transfers its
- Step 2: Citrulline combines with aspartate to give argininosuccinate synthase
- Step 3: Argininosuccinate is split into arginine and fumarate. The enzyme is argininosuccinase.
- Step 4: The carbon-nitrogen bond of the arginine is hydrolyzed in a reaction catalyzed by arginase to give the cycle product, urea, plus ornithine, ready to repeat step 1

Deficiencies of carnitine, carnitine acyltransferases, or carnitine/acylcarnitine translocase affect the metabolism of long-chain
fatty acids. Many of the symptoms are similar, and include hypoketotic hypoglycemia, low ketone levels and low blood sugar
with fasting, and damage to the liver, heart, or muscles due to fatty acid buildup in those tissues. Symptom severity varies with
the form of the deficiency.
The following abbreviations are used: carnitine acyltransferase (carnitine palmitoyltransferase), CPT and carnitine/acylcarnitine
translocase, CACT.
Identify each symptom or effect as a deficiency of CPT I, CPT II, or CACT.
CPT I deficiency
CPT II deficiency
CACT deficiency
Answer Bank
acyl carnitine not transported into mitochondrial matrix
acyl carnitine not converted to carnitine in matrix
long-chain fatty acids not transferred to carnitine
