Answer:

This is because in biology, energy is transferred from organism to organism and some energy is lost along the way. Each energy transfer results in a loss of energy, so that energy is always at a lower level and can never be returned to its original high energy level. On the other hand, chemical elements can form products, then that reaction can be reversed and break back down into reactants. Additionally, the law of conservation of matter says that matter can't be created or destroyed, only transferred from one form to another.

This confused me.

The answer is A, denature.

As each type of enzymes has its own optimum temperature, like the temperature that they work fastest at, so if the temperature goes too high above the optimum, the 3D structure of the enzyme breaks apart and deforms and they can no longer bind with substrates thus no longer works. In this scenario, we say the enzyme is denatured.

Note that only if the temperature is too high can make the enzyme denature, if the temperature is too low, instead, the enzyme would be inactive, but once the temperature goes back to normal, they work again. Unlike denatured enzymes, which does not work even if the temperature goes back to normal.
