BIOCHEMISTRY ACS EXAM PREP 2026
COMPLETE QUESTIONS WITH VERIFIED
ANSWERS GRADED A+
◉At pH 7, which amino acid is negatively charged?.ANSWER:-
Aspartic acid (Asp) is negatively charged at pH 7 due to its carboxyl
group being deprotonated.
◉The peptide bond is best described as:.ANSWER:-Planar with
partial double-bond character, which restricts rotation and gives the
peptide its structure.
◉Competitive inhibition affects which parameter?.ANSWER:-
Competitive inhibition affects Km only, increasing it while Vmax
remains unchanged.
◉Noncompetitive inhibition results in:.ANSWER:-Noncompetitive
inhibition results in the same Km but a decreased Vmax.
◉Which molecule activates PFK-1?.ANSWER:-AMP activates PFK-1,
promoting glycolysis when energy levels are low.
