Biology Review **Chapter for muscle contraction (1066-1074) Ch. 49 Exam 2: People in Action Cell Respiration Muscle Contraction Regulation of O 2 Supply to Tissues (muscles) Cell Respiration -glucose glycolysis pyruvate (no O 2 ) Anaerobic step (O 2 ) Into mitochondrion thru membranes into matrix Kreb’s cycle (Acetyl CoA ATP, NADH, FADH 2 ) Electron Transport Chain (inner membrane; makes much more ATP when oxidative phosphorylation occurs) gives off CO 2 and H 2 O -# molecules in each step (ATP, NADH, FADH 2 ), # molecules produced by 1 glucose Muscle Contraction -mechanical work (transport work/chemical work) -**explain how a muscle contracts (i.e. Ca cycle) -know the subunits (i.e. troponin, tropomyosin etc) -how they generate a whole muscle contraction from one twitch -know organismal level to molecular level (i.e. whole muscle fiber to single sarcomere, and part names) Regulation of O 2 to Tissues -PFK molecule, ATP:ADP ratios, phosphocreatine -model for gas exchange (see paint pic)
