1 animals used absorbed chemical energy for a exported chemi

1) animals used absorbed chemical energy for?

a. exported chemical energy, heat, and mechanical energry of external work

b. heat only

2) attempts to explain the mechanistic basis for the allometric scaling of metabolic have focused mostly on?

a. Circulatory system

b. lungs

c. Brain

3) Which of the following illustrates correct order of fuel utilization during muscle activity?

a. muscle glucose, muscle glycogen, phosphagens, glycogen brought in by the circulation

b. phosphagens, muscle glycogen, glycogen brought in by circulation, muscle glucose

c. phosphagens, muscle glucose, muscle glycogen, glucose brought in by the circulation

Solution

(a) is correct because chemical energy is required for all work ,chemical energy is converted in to biological currency

(ATP) for work .ATP is not transported from one cell to another only glucose (chemical energy ) is able to transport from one cell to another cell.
