Exercise 2: Skeletal Muscle Physiology: Activity 2: The Effect of Stimulus Voltage on Skeletal Muscle Contraction Lab Report Pre-lab Quiz 1. Skeletal muscle fibers are innervated (stimulated) by c. motor neurons. 2. A single action potential propagating down a motor axon results in d. a single action potential and a single contractile event in the muscle fibers it innervates. 3. In resting skeletal muscle‚ calcium is stored in c. the sarcoplasmic reticulum. 4. During the latent period

Activity 1 1. Size and concentration of the solute 2. It was too large to pass‚ as predicted 3. I predicted that the glucose would diffuse since it is small enough but the albumin is much too large to pass through the membrane. The experiment produced this result. Activity 2 1. Neither way requires ATP but facilitated diffusion requires carrier protein molecules for diffusion to occur. 2. By increasing the number of carriers more glucose can pass at a time increasing the rate‚
