X and Y.
It has 3 oxidation states bc it can participate in one electron and two electron transfers -
ANS-How many oxidation states does riboflavin have?

hydrogen bonding, their _____ _____ will correlate roughly with relative molecular
weight.

potential energy entire systemic circuit can be depicted as:
They add CO2- ADP and Pi are the byproducts. - ANS-What do carboxylase enzymes
add to the target molecule? What are the byproducts of this reaction?
6-8 - ANS-In H NMR, amide's tend cause shifts in what range?
active site - ANS-When a substrate is significantly changed, such as the enzymatically
stable product, it will very likely no longer fit in the _____ _____.
binding sites - ANS-A competitive inhibitor occupies ______ ______.
organic - ANS-Acetic acid is a weak, _____ acid.
They are both found of the interior protein. --hydrophobic side chains are likely to be
found in the interior of a protein rather than on its surface - ANS-On a globular protein,
where are leucine and phenylalanine residues most likely to be found?
P=IV
power= current * volts - ANS-What is the equation for power using current and volts?

termination and results in the entire sequence being copied every time and this creates
a single dark band instead of multiple shorter bands - ANS-After using the Sanger
method for DNA sequencing, a researcher utilizes gel electrophoresis and obtains a
single dark band. What is most likely the source of error?
PE=mgh

negative control - ANS-a control in which it does not provide any therapeutic or
medicinal effect
positive control - ANS-this control is a condition in which a treatment known to produce
therapeutic benefit to subjects is given and is often used to compare experimental
therapies

function
silent point mutation - ANS-this mutation does not change the expression of a protein or
the amino acid sequence of a protein. therefore, it would not be expected to have any
effect on enzyme function
penetrance - ANS-is a term used to describe if a genotype is expressed or not
expressivity - ANS-is a term used to describe the degree of expression of a phenotype
for a given genotype
