Question

walks from his dorm room to the woods nearby so he can begin his run. What did Joe's leg muscles use to produce ATP during this brief min) walk. 18) Joe A) Krebs cycle (tricarbowylic acid cycle) B) Glycolysis. Cori Cycle DO A & B A, B, & C 190 Joe begins to perspire at the begining of his run. The sweat was secreted from glands and results in evaporative cooling. A) merocrine sweat B) sebaceous sweat C) ceruminous 200 increased perspiration in response to increased body temperature is an example of A) feedback. positive feedback. feed forward. D) dysregulation. E) homeopathy. 21) After running for an muscles begin to fatigue. What causes this? the muscles. A) ng aerobic metabolism for an extended period of time will lower the pH in O Using anaerobic metabolism for an extended period of time will elevate the pH in the muscles. D) Depletion of energy stores and lowered pH in the muscles. flies everywhere so his leg muscles E) Joe's leg muscles are atrophied because Red Bull gives you wings. He aren't used. 22) The body responds to strenuous exercise as a form of stress. After running for an hour, which of the following occurring in Joe's body? A) The smooth muscle in the heart is contracting with maximum force with each heart beat. B) The smooth muscle in the small arteries supplying the skeletal muscles are relaxed. His pupillary dilator muscles are relaxed and the pupillary constrictor muscles are contracted. D) The smooth muscle in the small arteries supplying the skeletal muscles are contracted. E) The smooth muscle in the small arteries supplying the gastrointestinal tract muscles are relaxed. A) Krebs cycle (tricarboxylic acid cycle). B) Glycolysis. Cori Cycle D) A & B E) A, B, & C

Explanation / Answer

1) because he is normally walking so no need to produce energy rapidly. so ATP is produced by Glycolysis and Krebs cycle both. option D.

2) merocrine or eccrine gland. option A.

3) negative feedback. option A.

4) using aerobic metabolism for an extended period of time will lower the pH of the muscle. (due to production of lactic acid).

5) the smooth muscle in the heart is contracting with maximum force with each heart beat.

6) option D.

7) organ of Corti, cochlear.

8) crista, vestibular

9) macula. vestibular.

10) using creatine phosphate to produce ATP from ADP.

11) otion B. higher refractory period.
