Under cellular conditions when cholesterol is low, which of the
following is a true statement regarding the sterol response element
binding protein?
Give this one a try later!
, It will inhibit transcription of It will be associated with the
cholesterol-related genes sterol response element (SRE)
on the DNA
It will bind to the mitochondrial
It will be degraded in the cytoplasm
membrane

What is the regulatory enzyme in bile acid synthesis?
Give this one a try later!
urea; pyrimidine synthesis
malonyl coa
point of origin.
vldls are produced in the liver following the process of lipogenesis (insulin -
stimulated) where excess glucose --> fatty acids and esterified into tags, the tags
are then packaged w/ cholesterol, phospholipid, and proteins to form vldl
chylomicrons are produced from dietary lipids
7 a-hydroxylase
Inhibited by bile acids
Don't know?

, What is pyroxidial phosphate used for?
Give this one a try later!
B6 -enzyme needed for moving amine groups to keto acids
(aminotransferases)
Also required in metabolism of cysteine
extrahepatic lipoprotein lipase
Used to degrade TAG in chylomicrons and VLDLs
- generation of energy in TCA cycle in the mitochondria
- excess acetyl coA liver is converted to ketone bodies
- used for fatty acid synthesis and sterols in cytosol
NOT a substrate for GNG
To decrease accumulation of uric acid
adenine and HGPRT are enzymes used to break down purines into GMP or IMPT
Also purines are double ringed, harder to break down so easy to recycle
