Hydrophobic effect Study guides, Class notes & Summaries

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...

(T/F) A biochemical reaction, without a catalyst or thermodynamic coupling, takes 50 years to reach a state of equilibrium. Without more information, we cannot make a determination on either the value of the Keq constant or the positive or negative value of the ΔG of the reaction. Correct Answer-False (T/F) Due to its small size, the amino acid glycine can be found in tight turns in a protein structure. Correct Answer-True (T/F) The ΔG of a reaction is defined as the energy required to b...

UNIT 4 REVIEW BIO 1510 QUESTION AND ANSWERS (VERIFIED ANSWERS) In eukaryotes, the idea that one gene codes for one protein has been modified because - ANSWER one gene can code for multiple proteins via alternative splicing. Which of the following would decrease the amount of a protein in a eukaryotic cell? - ANSWER Increasing the ubiquitination of the protein Which of the following would be most likely to bind to a hydrophobic ligand? - ANSWER an intracellular receptor When a receptor...

functions of the membrane correct answer: -the structure of the membrane is key for its function -act as a barrier regulating import and export of molecules -help with compartmentalization of the cell, creating particular environments for certain processes so multiple specialized processes could occur at once -modulates cell-cell recognition with their glycoproteins and glycolipids located on the outer leaflet facing the cytosol -signaling across the membrane by proteins and lipids p...

WGU Biochemistry Final Review 1. The polymerase chain reaction is a tool used to study protein structure. True False False Feedback PCR is a tool used to amplify a specific segment of DNA. What color is the primer in the following diagram? Red Purple Blue Red Feedback Recall from the section on DNA replication that DNA polymerase needs a primer to begin DNA synthesis. This requirement means the primers will direct the DNA polymerase to only synthesize complementary stran...

PeptideT or F? Peptide bonds behave as rigid planes because of partial double-bond character between the carbonyl carbon of one residue and the amide hydrogen of another residue. Correct Answer-FAlSE! B/C Hydrogen can't have a double bond, but if it stayed nitrogen it would be true. T or F? The process by which hydrophobic molecules are driven together, therefore maximizing the entropy of water, is referred to as the Hydrophobic effect. Correct Answer-TRUE! The strong electronegativity is...

Functions of biological membranes correct answer: - barrier (import/export) -compartmentalization of essential molecules (incrs. efficiency) - cell signaling-mediated by pr & lipids (receptors) - modulate cell-cell recognition (glycoproteins & glycolipids) What's responsible for membrane formation correct answer: decrease in ionic interactions w/ h2o (HYDROPHOBIC EFFECT) -h20X tails aggregate to hide from h2o (lots of n-c interactions) -polar heads interact w/ h2o Decreases membrane ...
