MCB 32 : Human Physiology Jason Yu (  sunnyjason@berkeley.edu   ) Discussion Sections 107  W8-9    182 Dwinelle 108  W3-4    122 Wheeler 111  M1-2    215 Dwinelle Office Hour F 9:30-11   449 LSA Chap6 A . Diffusion B . Carrier-Mediated Transport : Protein carriers – characteristics of enzymes                       Specificity / competition / saturation / inhibition by blockers Facilitated diffusion : ex. GLUT(glucose transporter) Active transport : against concentration gradients by using energy 1. Primary active transport : using ATP                          ex. Na+/K+ pump 2. Secondary   active   transport:   using   one   molecule’s   downhill  transport      (coupled transport)      ex. Na+/glucose transporter                                      cf. co-transporter(symporter) vs. antiporter                              C . Membrane potential : Na+ vs K+
