Document Content and Description Below
Explain the protein functions of the sarcomere: The function of myosin is converting chemical energy into ATP. The function of actin is dividing cells in order to enable cells. The function of the ... z band is being responsible for muscle contraction. 1. The two types of myofilaments are thick myofilament which is made up of myosin, and thin myofilament which is made up of of actin. 2. The plasma membrane of the myofiber is called the sarcolemma. 3. The sarcomere is the region between two Z-discs. 4. The sarcoplasmic reticulum is similar to the endoplasmic reticulum. 5. Dark bands are made up of thick myosin filaments, whereas light bands are made up of think actin filaments 1. What happens to the diameter of the muscle when it is contracted? 2. What is happening in the individual muscle cells that might explain this result? 3. What type of experiment might allow you to test this hypothesis? [Show More]
