BCHM 307 Exam | Quizzes and 100% Correct
Verified Solutions
Pathways leading to essential amino acids are good targets for ___ - Answer herbicides
Glyphosphate (Roundup) is an inhibitor of ___, an enzyme of the shikimic acid pathway -
Answer EPSP synthase
Glyphosphate blocks __ - Answer Blocks the production of aromatic amino acids
Ascorbic acid (vitamin C) is required for the production of - Answer Hydroxyproline and
hydroxylysine, both of which are found in connective tissue
A deficiency in Vitamin C is known as __ - Answer scurvy
Acids are proton ___, and bases are proton ___ - Answer donors, acceptors
Acids dissociate into __ and a conjugate ___ - Answer protons, base
Bases associate with ___ to become their conjugate ___ - Answer protons, acids
Why are acid/base properties important? - Answer Because many biochemical
compounds are either acids or bases or both they can influence the relative abundance
of protons in the cell
Similarly, the relative content of protons (H+) in solution dictates pH which in turn
dictates the ionization state of biological molecules.
, What does the pKa of an acid or base tell us? - Answer The pKa for a functional group is
the pH at which the acidic or basic group on 50% of the molecules in a solution are
deprotonated
Many common biochemical compounds are acids and/or bases that vary widely in their
pKa values
All amino acids have acidic and basic ___ groups - Answer functional.. the carboxyl
group is acidic and the amino group is basic
Amino acids that lack charged R groups exist as ___ at neutral pH - Answer zwitterions
Have a charged R group - Answer Cysteine
Tyrosine
Aspartate
Glutamate
Histidine
Lysine
Arginine
Amino acids are linked together by ___, involves the removal of the elements of water,
and charge - Answer peptide bonds
A peptide bond is formed between the __ of the first amino acid and the amino group of
the "next" - Answer carboxyl group
Insulin regulates - Answer regulates glucose uptake
