After detailed studies, defective carnitine biosynthesis is identified. This molecule is necessary for which of the following biochemical functions?
A. Carboxylation of glutamic acid
B. Decarboxylation of alpha-ketoacids
C. Synthesis of 1,25-dihydroxycholecalciferol
D. Synthesis of rhodopsin ii photoreceptor pigments of the eye
E. Transport of long chain fatty acids into mitochondria

E. Transport of long chain fatty acids into mitochondria

E. Transport of long chain fatty acids into mitochondria

Yup agreed... E.

 

[sam01]

YES.you re right.Carnitine is important in transferring fatty acids from the cytoplasm into the mitochondria (the carnitine shuttle).So,it is involved in the oxidation of fatty acids

woohoo!! i guessed E too before looking at the answer!

cool. thanks sam!
