BCHM-3050 Study Guide - Midterm Guide: Buffer Zone, Protein Folding, Ramachandran Plot
Document Summary
Study guide exam 1 bio chemistry 3050. Nacl is stronger and needs more energy to be broken apart: what is osmotic pressure, the pressure required to stop the net flow of water across the membrane. This pressure is exerted to counteract the forces that are caused by osmosis: osmosis- water movement from low concentration high concentration, explain isotonic, hypotonic and hypertonic solutions. Isotonic balance of solute concentration inside and outside the red blood cell: hypotonic concentration of solute inside the rbc is less than the concentration outside. If too much water leaves, the rbc can shrink: hypotonic concentration of solutes inside the rbc is high than the concentration outside. This is essential for all living things: buffers help maintain a constant hydrogen ion concentration, buffer zone where the ph is not changing because the weak acid and conjugate base are maintaining equilibrium at a certain concentration. This is when buffers are most effective: henderson-hasselbalch equation:
