pKa (chapter 3) correct answers measure of the tendency of a group to give up a proton (acidity); tendency decreases tenfold as pKa increases by one unit thioester bond (1) correct answers compounds with functional group C-S-CoA-C (eg, in acetyl-CoA) zwitterion (3) correct answers dipolar ion with both positive and negative groups but overall neutral charge; can act as either an acid or base Isoelectric point (pI) (chapter 3) correct answers the characteristic pH at which the net electr...

Biochemistry- AAMC FLASH CARDS fully solved 2023The Michaelis-Menten Kinetic equation - correct answer Which combination of lipid type and temperature results in the most disordered membrane? - correct answer Lipid with unsaturated acyl at high tempearture Because unsaturated acyl chains do not pack well well together. They are a mess. When you add high temperature they become a hot mess. Because they is more movement in high temps. The side chain of which amino acid is most likey to f...
