1. According to the sliding filament theory, what is the initial action in a muscle contraction? a. Troponin is freed and prevents actin and myosin from reacting with each other. b. Calcium binds to troponin, which causes the release of actin and myosin binding sites. c. Actin and myosin molecules react with each other sliding along the filament and making it shorter. d. Muscle filament relaxes or slides back to the resting position. Ans: C Feedback: Actin and myosin molecules react wi...
