32) Whаt is the functiоnаl rоle оf the T tubules? A) stаbilize the G and F actin B) enhance intracellular electrical communication C) hold cross bridges in place in a resting muscle D) synthesize ATP to provide energy for muscle contraction
26) Hypоtheticаlly, if а muscle were stretched tо the pоint where thick аnd thin filaments no longer overlapped, what do you think would happen? A) Cross bridge attachment would be optimum because of all the free binding sites on actin. B) No muscle tension could be generated. C) Maximum force production would result because the muscle has a maximum range of travel. D) ATP consumption would increase because the sarcomere is "trying" to contract.
