Please help answer questions 40-50

The enzyme carbomoyl phosphate synthetase (urea synthesis) is allosterically activated by a derivative of A. Alanine B. Glutamate C. Aspartate D. Phenylalanine E. Tyrosine The urea cycle is active in the following organs: A. Skeletal muscle B. Liver C. Adipose tissue D. A and B are correct E. All of the above omega - x fatty acids contain "x" double bonds Uncouplers inhibit electron flow in the respiratory chain Many vitamins are required for the synthesis of co-substrates Uncontrolled Type l diabetics may produce ketone bodies even after a meal Free glycerol cannot be used by any organ except for skeletal muscle VLDL are synthesized in the liver Glutamate dehydrogenase produces free NH^+ _4 in liver mitochondria The concentration of hemoglobin A1c increases with hyperglycemia The urea cycle is never inhibited

Explanation / Answer

Question 40

glutamate

Question 41

liver

urea cycle.

This converts excess ammonia into urea in the mitochondria of liver cells.

Question 42

true

Omega x-fatty acids contains x –double bonds

Question 43

true

Uncouples inhibits electron flow in the respiration

Question 44

true

Many vitamins are required for the synthesis of co substrates

Question 45

true

Uncontrolled type 1 diabtetics may produce ketone bodies even after meal

Question 46

false

Fee glycerol canto be used by any organ except for skeletal muscle

Question 47

true

Very low density lipoprotein (VLDL) is the major vehicle in the plasma which carries triacylglycerolsynthesized in the liver

Question 48

true

Glutamate- + NAD(P) + + H20. -à

Oxoglutarate 2- + NAD(P)H +NH4 + + H +

Question 49

true

The concentration of hemoglobin A1c increased with hyperglycermia

Question 50

false

Question 40

glutamate

1. glutamate +acetyl CoA use the enzyme N-acetyl glutamate synthase to make--> N-acetyl glutamate.

1. N-acetyl glutamate allosterically activates carbamoyl phosphate synthetase I.
2. Arginine acts as a feed forward activator by allosterically activating N-acetyl glutamate synthase
