Survey of Diversity of Life• 6 Kingdoms
– Prokaryotes (Bacteria and Archae)• Both unicell, small, circular chromos, binary fission, no compartments, simple flagella, diverse
– Muscle fibers-myofibrils-myofilaments-sarcomere• Sliding filament theory (thin actin slides in towards myosin)• Troponin holds tropomyosin preventing mysoin heads from
binding to actin• Ca++ removes troponin, loosening tropomyosin, myosin binds to
actin, shifts, releaing ADP/Pi, ATP added to release– ATP also needed to pump Ca++ back into SR
» Glucose and glycogen– Nerve cell transduces signal, releases Acetycholine to transduce
