Lineweaver burk plot - Study guides, Class notes & Summaries

(T/F) Acid-base catalysis involving free protons or hydroxide ions is thermodynamically favorable because these are already in high concentrations in the cell. Correct Answer-False (T/F) The glycerophosopholipids of a membrane bilayer have been modified to contain additional double bonds. This change will likely lower the activation of adenylate cyclase by a G-protein. Correct Answer-False (T/F) To be inserted, a α-helical integral membrane protein requires at least one helix that is at l...
