BIOLOGY 288 Study Guide - Midterm Guide: Stroke Volume, Glycogen, Starling Equation
Document Summary
Below is a list of essential concepts you should be familiar with for the second exam. This is not a comprehensive list, as you are responsible for all the material from this section of the course. However, this guide will help you focus your study efforts. Know the basic muscle anatomy (fig 12. 1) as well as the cellular anatomy (sr, t- tubules etc). Cellular anatomy: components of a muscle fiber. Triad: t tubule + lateral sacs: structure at the molecular level: myofibrils- give skeletal and cardiac muscle striated appearance. Actin and myosin are myofibrils: thick and thin filaments run parallel to long axis, filaments form sarcomeres, structure of a sarcomere. Z line to z line: actin. Contractile protein, each g actin had binding site for myosin: tropomyosin. Overlaps binding sites on actin for myosin: troponin. Calcium binding to troponin regulates skeletal muscle contraction: thick myofilaments. Actin binding sites, and nucleotide binding site for atp and.
