it allows scientists to look at and examine the brain without having to operate on a patient. considering all that could go wrong with brain surgery, neuroimaging is a safer alternative and is more conductive to education, as the scans can be shared and compared.
Explanation:
Answer & explanation:
Amylase is part of enzymes, a group of large peptide molecules (formed by amino acids) whose role is to catalyze reactions in order to facilitate the synthesis of other biological molecules.
Amylase is found mainly in saliva (in the form of salivary amylase, or ptialin), acting in the breakdown of starch and glycogen in foods, reducing them to smaller particles, facilitating their digestion and absorption.
The action of enzymes depends on certain specific conditions, called optimal conditions. In the case of <u>amylase</u>, it depends on an optimum pH of 7 (neutral) and an optimum temperature of approximately 37 ° C.
This enzyme can still act between 35 ° C and 40 ° C, but below 35 ° C it is inactivated, preventing its functions from being performed, and above 40 ° C it suffers denaturation, causing changes in its structures.
Thus, it is concluded that the <u>temperature</u> (under optimal conditions) is important for enzymes because it keeps their actions and structures in proper operation.
