Question

When you eat a hamburger, some of the energy in the food is converted to ATP that your cells can use to do all kinds of work, some of the energy is stored for later use, and some of the energy is dissipated as heat. The amount of energy before and after eating the hamburger is the same. This illustrates the:
a. first law of thermodynamics
b. second law of thermodynamics
c. theory
d. the theory of evolution
e. central dogma

Answer 1

Answer:

The correct answer will be option-A

Explanation:

The first law of thermodynamics states that in an isolated or closed system the energy remains conserved. This shows that energy is neither created nor destroyed but changes its form from one to another.

In the given condition, since the energy provided by the ATP is used during the metabolic reactions, some are lost as heat energy and some is stored in the form of molecules for later use.

This shows that energy is not lost but changed its form from chemical to heat and some remain to chemical form. Therefore, this follows the first law of thermodynamics.

Thus, option-A is the correct answer.
