what does the biological activity of a protein depend on? Correct Answer-it's 3D structure and its interaction with other molecules prosthetic group Correct Answer-a metal ion or organic compound (other than an amino acid) covalently bound to a protein and essential to its activity modification types of amino acids Correct Answer- primary structure Correct Answer-a description of the covalent backbone of a polymer, including the sequence of monomeric subunits and any interchain and int...

ligand Correct Answer-a small molecule that binds specifically to a larger one (i.e., protein). For example, a hormone is the ligand for its specific protein receptor [a molecule bound reversibly by a protein. binding site Correct Answer-the location (crevice or pocket) on a receptor protein to which a ligand binds induced fit Correct Answer-The change in shape of the active site of an enzyme so that it binds more snugly to the substrate, induced by entry of the substrate. Renders the subs...

Unit 8 BIOMG 3300 questions with complete solutions

R1-R2C=NH Correct Answer-imine RO-CO-CH3 Correct Answer-acetyl R-SH Correct Answer-sulfhydryl/thiol R-CO-SR Correct Answer-thioester RO-PO2-OH Correct Answer-phosphoryl hydrogen bond Correct Answer-an electrostatic attraction between the O of one molecule and the H of another H must be bonded to F,O,N H bond acceptor Correct Answer-a LP on an electronegative atom H bond donor Correct Answer-an H bonded to F,O,N amphipathic molecule Correct

What was originally considered to be the genetic material? Why? Correct Answer-Proteins were considered to be the genetic material because they were inherently more complex than DNA. Avery, McCarty, MacLeod experiment Correct Answer-First, think about Griffith's experiment and how even heat killed strains of S. pneumococcus still led to death of non pathogenic cells ⁃ Process: Grind up virulent cells, isolate the active genetic material ('transforming principle') and infuse it into non...

What factors affect binding affinity? Correct Answer-Shape, charge, H-bonding, hydrophobics reversible binding Correct Answer-the association of a protein with its ligan is concentration-dependent K_d Correct Answer-the concentration of ligand at which 1/2 of the protein is ligand-bound K_d = k_d / k_a or k_off / k_on also = k_-1 / k_1 Calculate fraction of protein bound to ligand Correct Answer-[L] / ([L] + K_d) affinity and concentration association Correct Answer-if they bind at...
