Agroup of students has performed an experiment to study the ideal temperature for the maximum activity of biological enzymes. enzymes are specific to their environment; in other words, they work best at a specific ph and specific temperature. which graph represents optimum enzyme activity at approximately 37 degrees celsius?
refer to figures below.

Answer;

The first graph represents such an enzyme.

Explanation;

This is because the enzyme demonstrates greatest activity at approximately 37 °C but then the activity starts to decrease due to the denaturing of the enzyme.

As the temperature increases, so does the rate of reaction. But very high temperatures denature enzymes. The graph shows the typical change in an enzyme's activity with increasing temperature. The enzyme activity gradually increases with temperature up to around 37 ºC, or body temperature. Then the activity decreases above 37  ºC, because above this temperature the enzymes will denatured.

the relative atomic mass of an element is the mass of one atom of that element, relative to 1/12th of the mass of a  1212c atom. to convert to an absolute mass in kg, it is necessary to multiply by  1.661×10−271.661×10−27.

the relative atomic mass is roughly equal to the number of neutrons, plus the number of protons, in the nucleus of the atom.

for elements with more than one stable isotope (different types of nucleus with different numbers of neutrons but the same number of protons), the quoted mass is usually the average mass, weighted by the relative abundance of the different isotopes.
