What is the major provider of carbons for gluconeogenesis in the ABSENCE of
glucose? correct answer -Amino Acid
What is Transamination? correct answer -The process in which an amino
group is removed from an amino acid and placed onto the a-keto acid, creating
a new alpha-leto acid and a new amino acid
What is not an example of a nitrogen containing compound that is NOT an
amino acid? correct answer -Carnitine, Carnosine, Choline
Why would someone want to take carnitine supplements? correct answer
-Excess carnitine may speed up fatty acid transport into mitochondria
increasing beta-oxidation and helping burn more fat
What is the main difference between peptide hormones and steroid
hormones? correct answer -Peptide hormones bind to cell membrane
receptors, while steroid hormones cross the cell membranes and bind to
cytosolic receptors in target cells
Which organ does gluconeogenesis take place? correct answer -Liver
How many net carbons does acetyl-CoA contribute to new glucose through
gluconeogenesis? correct answer -0
What is the name of the process by which lactate is converted into glucose?
correct answer -Cori Cycle
During the state of adapted starvation, what is the primary source of energy?
correct answer -Fatty Acids
During stress/trauma, hyperglycemic conditions will cause what main fuel
source to be used for energy? correct answer -Amino Acids
Which hormones is more active during negative energy balance? correct
answer -Glucagon
, What is this: A DNA sequence variation that can alter the structure and
function of the protein product, but is not lethal correct answer -
Polymorphism
Fatty Acids can be used to synthesize all except? correct answer -Pyruvate
Epigenetic's changes to DNA are heritable (can be passed to offspring), even
though they do not result in changes to DNA sequence correct answer -
True
Epigenetic's is reversible? correct answer -True
Nitrogen waste from amino acid degradation is excreted in the urine in the
form of? correct answer -Urea
During stress/trauma, what effect do cytokines have on glucose metabolism?
correct answer -Cytokines create a signaling cascade that leads to the
repression of phosphorylation in the insulin signaling pathway, derailing
glucose metabolism
What are examples of peptide hormones? correct answer -Gastrin, GH
What are examples of steroid hormones? correct answer -Catecholamine,
estrogen, testosterone, aldosterone, glucocorticoids
Which cannot be generated by amino acids? correct answer -Hydrochloric
acid
Which of the following is NOT a post-translational modification of proteins?
correct answer -Evapotranspiration
Which hormone is most active during positive energy balance? correct
answer -Insulin
What is the Human Genome Project? correct answer -The vast majority of
disease are not related to genetics, but to proteomics (the profile of proteins
present in an individual) and environmental exposures
In what organ does the urea cycle occur? correct answer -Liver
