Question

Cells usually cannot use heat to power mechanical work because

A) after several energy conversions, there is not enough energy in heat to power cellular functions
B) as the heat increases the cell’s temperature, it must be released to prevent cell damage
C) heat is a waste product of chemical reactions and not a true form of kinetic or potential energy
D) there is not enough of a temperature difference within the cell for heat to be able to flow

Answer 2

What do you think???

Answer 3

I think it is B @Rubyjadeluv

Answer 4

Most cells use chemical energy and have various organelles use chemical energy to undergo their metabolic processes. Heat is a type of energy, however, it's thermal energy. Also, cells can somewhat harness heat to do work because their reliance on enzymes. Enzymes work to lower the activation energy of various metabolic processes and particular enzymes function better and varying temperature and pH.

Answer 5

Wait so I am wrong then? @Rubyjadeluv

Answer 6

Also consider that most animals internal temperatures remain relatively stable (homeostasis). If cells were to harness heat, or thermal energy, they may send the organism's body out of equilibrium. I think you are corrcet

Answer 7

Oh great! thank you!
