Question

Cells usually cannot use heat to power mechanical work because (2 points)


Question 2 options:


1) 

after several energy conversions, there is not enough energy in heat to power cellular functions


2) 

as the heat increases the cell's temperature, it must be released to prevent cell damage


3) 

heat is a waste product of chemical reactions and not a true form of kinetic or potential energy


4) 

there is not enough of a temperature difference within the cell for heat to be able to flow

Answer 1

The answer is; option 2

The cell must maintain a homeostatic temperatures of 37 degrees centigrade in humans. Therefore heat is less likely to be used to power mechanical work because it has to be kept constant. Heat ,also, cannot be stored when it increases in the cell, the way energy is stored in chemical bonds in ATPs.
