Leya [2.2K]

Answer:

The Miller and Urey experiment is a well-known classic experiment in which hypothetical conditions of the early Earth's evolution were simulated to test the possibility of chemical evolution. In fact, this was an experimental test of the hypothesis previously expressed by Alexander Oparin and John Haldane that the conditions that existed on primitive Earth promoted chemical reactions that could lead to the synthesis of organic molecules from inorganic ones. It was held in 1953 by Stanley Miller and Harold Urey. The apparatus designed for the experiment included a mixture of gases corresponding to the notion of the composition of the atmosphere of the early Earth in the 1950s, and electric discharges passing through it (simulating lightning strikes on the ground). The Miller and Urey experiment is considered one of the most important experiments in the study of the origin of life on Earth.

How would someone measure the effect of pH on the rate<br> ofenzyme reaction?
wlad13 [49]

Answer:

It can be determined by measuring product appearance or reagent disappearance also enzymatic activity (described below )

Explanation:

Effect of pH on enzymatic activity

PH effect: affects the state of dissociation of the groups, although all proteins are not affected in the same way because some do not have dissociable groups. Most enzymes have an optimal pH. If there are small changes in pH, the enzyme is not denatured. The pH can affect in two ways:

The substrate binding is better or worse than before.

That affects the catalytic speed of the reaction.

The enzymatic speed is measured in M ​​/ t and the enzymatic activity in mol / t, and the international unit μmol / min, amount of enzyme that transforms a micromol from substrate into product in one minute under optimal conditions. Another unit is the enzymatic amount that is required to transform 1 mol / s and is called katal.
