Most enzymes work best at 37C because at lower and higher temperatures, the conditions are not optimal for their performance. Ex

That's because the solubility

Temperature is directly proportional to solubility

Higher the solubility higher the temperature

Lower the temperature lower the solubility

Less temperature makes enzymes work faster

Where do the gaseous elements tend to be located on the table

kotegsom [21]

Answer:

Group 8 or Group 0

Explanation:

Group 8 or Group 0 are generally inert gases with Helium as the first member in that group. Their complete duplet (in the case of Helium) and Octet (in the case of Neon) configuration makes them very stable and chemically un-reactive.
