1 FADH2 and 1 NADH - ansThe conversion of palmitoyl-CoA to myristoyl-CoA by the beta oxidation
pathway results in the net formation of?
7 - ansHow many rounds of beta oxidation would be required for a 16-C fatty acyl chain to be degraded to
acetyl-CoA?
a balance exists between rates of anabolism and catabolism - ansIn steady state metabolism?
acetyl-CoA - ansCholesterol is synthesized from?
act through binding receptors - ansAll hormones?
Acyl-carnitines readily cross the mitochondrial inner membrane, but acyl-CoAs do not - ansFatty acids are
activated to acyl-CoAs and the acyl group is further transferred to carnitine because?
alanine - ansWhich of the following compounds serves to transport excess ammonia from muscle to liver
for urea synthesis ?
alpha ketoglutarate - ansGlutamate can be synthesized directly from?
an amino acid that cannot be made by humans and must be obtained in the diet - ansWhich of the
following best defines an essential amino acid?
an inability to respond to insulin - ansOf the two types of diabetes, which of the following situations is
unique to type 2 diabetes ?
an increase in the number of double bonds - ansThe fluidity of the lipid in the interior of a bilayer is
generally increased by ?
Atherosclerosis - ansHigh levels of cholesterol in the blood can lead to?
Atherosclerosis is not linked to high LDL - ansEach of the following statements are true for lipoproteins,
except?
bile salts - ansCholesterol is not oxidized for energy within the body, but you might eliminate it from your
body if you could increase the formation of?
blood glucose levels of diabetics tend to be higher - ansHow does the blood glucose levels of diabetics
tend to compare to normal ?
brain - ansWhich of the following tissues cannot use free fatty acids from blood for energy but can use
ketone bodies as an energy source?
can be synthesized in humans - ansNonessential amino acids?
carried by the protein serum albumin - ansFree fatty acids in the bloodstream are ?
Citrate - ansIn order to synthesize fatty acids, acetyl-CoA is shuttled out of mitochondria as?
driven by a concentration gradient - ansFacilitated diffusion (passive transport) through a biological
membrane is ?
Facilitated diffusion - ansWhich of the following transport processes requires no energy?
