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.

UNO [17]

Answer:

Filip's medical report, diagnosed with Alzhaimer's, may reveal a diminished production of acethylcholine.

Explanation:

Alzhaimer's disease is a neurodegenerative condition that causes immediate memory loss, behavioral changes and cognitive impairment, due to neuronal alterations and atrophy.

The neurotransmitter acetylcholine —related to neuronal transmission and body movement— may experience a decrease in its production leading to Alzheimer's, according to the cholinergic hypothesis.

Many therapies and treatments at present are based on the use of drugs to correct the acetylcholine deficit.

Regarding other options:

<em>Dopamine: alteration or deficit is related to Parkinson's disease.</em>
<em>Gamma aminobutyric acid (GABA): deficiency is not common and is related to a type of congenital and infantile neuropathy. </em>
<em>Serotonin: deficit of this neurotransmitter can lead to depression and psychological disorders.</em>
