Question

24. As muscles progress from a single twitch to unfused tetany, what happens to muscle tension a. Stays unchanged b. Increases c. Decreases d. Increases then decreases e. Decreases then increases 25. An oxygen deficit results in a. Increasing glucose levels b. Increasing glycogen levels c. Increasing pyruvic acid levels d. Increasing fructose 6 phosphate levels e. Increasing lactic acid levels. 26. Which one of the following is NOT typical of the changes that follow the binding of a hormone to it target cell? a. cellular mutations occur b. proteins are synthesized in the cell c. enzymes are activated or inactivated d. plasma membrane permeability changes

Explanation / Answer

24.As muscle progress from single twitch to unfused tetany, what happens to muscle tension, it will stay unchanged(constant). the twitch muscle is a small contraction caused by one action potential,in unfused tetany there is partial relaxation between stimulus so muscle tension remains constant. 25.An oxygen deficit results in increasing lactic acid levels, oxygen deficit is the amount of oxygen that the subject was short of during the excersice. 26.cellular mutations is not typical of the changes that follow the binding of a harmone to its target cell, when a harmone binds to the target cell changes in plasma membrane permeability occurs, synthesis of proteins occurs, activation or inactivation of enzymes occurs
