why are glutamine levels elevated in urea cycle deficiencies?
In the urea cycle; A. Carbamoyl phosphate is derived directly from glutamine and carbon dioxide B. Ornithine reacts with aspartate to generate argininosuccinate C. The amino group of arginine forms one of the nitrogens of urea D. Ornithine directly reacts with carbamoyl phosphate to form citrulline E. N-acetylglutamate is a positive allosteric effector of Ornithine transcarbamoylase (OTC)
The "missing" molecule that allowed Krebs to work out the urea cycle pathway is_____________. fumarate carbamoyl phosphate ornithine citrulline arginosuccinate The first nitrogen in the citric acid cycle is introduced by what molecule? glutamic acid carbamoyl phosphate glutamine directly from ammonia please answer both of them
why does my patient have elevated levels of epinephrine, aldosterone and angiotensin?
Using this diagram, explain why: a. A woman with elevated LH levels and low FSH levels might not ovulate: b. A woman with an estrogen-secreting ovarian tumor might have endometrial hyperplasia: c. A woman with decreased progesterone levels might have an extra thick uterine lining, leading to heavy menstrual bleeding (menorrhagia): d. A woman with a pituitary infection might not menstruate (amenorrhea): e. An injection of FSH might be given to an infertile woman:
A newborn girl appeared normal at birth, but within 24 hours she developed lethargy, hypothermia, and apnea. The attending physician suspects a metabolic disorder and orders a panel of labs. Which diagnostic would be the best to distinguish between a urea cycle disorder and a disorder in β -oxidation? (Please discuss your rationale for this choice) a. Blood glucose b. Urinary acids c. Serum fatty acids d. Plasma glutamine A full blood work up was ordered for this female and...
