how are H bonds formed in beta sheets? Correct Answer-- between strands - H-bonds are lateral why do proteins fold if it would lower entropy? Correct Answer-- the hydrophobic effect - deltaH --> all of the interactions happening w/in the protein are favorable + overcome the unfavorable entropy of folding what types of interactions stabilize 3* structures? Correct Answer-- H-bonds - ion pair / salt bridges - van der Waals interactions: weak electrostatic interactions b/t induced dipo...

BIOL2200 MID SEMESTER PRACTICE EXAM 2024 WITH 100% CORRECT ANSWERS Phospholipid bilayers are NOT stabilised by: a. van der Walls forces b. covalent bonds c. hydrogen bonds d. ionic bonds e. hydrophobic interactions - correct answer b. covalent bonds A transmembrane protein has the following properties: it has two binding sites, one for solute A and one for solute B. The protein can undergo a conformational change to switch between two states: either both binding sites are ex...

BCH4024 TEST 1 QUESTIONS WITH COMPLETE SOLUTIONS diffusion-limited process: - Answer-reaction rate is determined by how fast reactants collide the Protonation and deprotonation of macromolecules? - Answer-acid/base groups on surface react immediately acid/base groups deep inside may never ionize hydrogen bonds of buried helices and beta-sheets require the "conformation breathing" -local unfolding Pepsin - Answer-a digestive enzyme secreted into gastric juice, having a pH of 1.5 a...

Phospholipid bilayers are NOT stabilised by: a. van der Walls forces b. covalent bonds c. hydrogen bonds d. ionic bonds e. hydrophobic interactions - b. covalent bonds A transmembrane protein has the following properties: it has two binding sites, one for solute A and one for solute B. The protein can undergo a conformational change to switch between two states: either both binding sites are exposed exclusively on one side of the membrane, or both are exposed exclusively on the ot...
