What is the biological significance of the temperature at which the amylase
kati45 [8]

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.

Please hurry<br> Explain the connections among air pressure, temperature, humidity, and fronts.
Soloha48 [4]

Air mass is a large body of air that exhibits uniform temperature and moisture characteristics and helps to determine the weather within an area. Warm air masses tend to form over oceans in warm-temperature regions of the tropics and sub-tropics, while cold air masses tend to form over land in cold-weather regions nearer the poles. The cold air masses that form at the poles move toward the equator, while the warm air masses that form at the equator move toward the poles. These air masses can undergo gradual, but significant, changes as they pass over warmer or colder land surfaces encountering different types of air. These boundary lines are called front.
