Muscular System

• Exercise increases the number of carriers for the facilitative diffusion of glucose in the muscle cell membrane (p. 343)

• Ca2+ transport processes in the endoplasmic reticulum of skeletal muscle fibers are important in the regulation of muscle contraction (p. 336)

• Voltage-gated Ca2+ channels in the cell membrane of smooth muscle open in response to depolarization, producing contraction of the muscle (p. 355)
