zero after decimal are all significant . zero before decimal is significant only when it is preceded by a digit.All digits are significant.
Answer:
The correct answer is D) hydration
I can’t answer the exact thing, but I know how to do it. One of the nitrogen bases always pairs with a different one, so once you know what pairs with what you just write it down. If you need more help just ask :) tip: one base will only join with a different one. One won’t join to multiple (from what I know as of now)
Answer:
d. A competitive inhibitor, collect kinetic daa both in the presence and absence of inhibitor and watch for a change in Km.
Explanation:
According to the description, the inhibitor was designed in a way when it binds the enzyme, the transition state achieved will be close to the one observed when the substrate binds.
In other words, the aim was to design an inhibitor that will bind the free enzyme in a reversible way, competing with the substrate for the binding sites.
As the inhibitor will be binding the same site as the substrate, the apparent affinity of the enzyme for the substrate will decrease. And the higher the affinity of the inhibitor for the enzyme, stronger the effect it will have over the affinity of the enzyme for the substrate.
Quantitatively speaking, the apparent Km of the enzyme for the substrate will increase with the inhibitor concentration, as the affinity of the enzyme for the substrate decreases.
In summary, what is being engineered is a competitive inhibitor, and the way of knowing if the design was successful, is collecting kinetic data in presence and absence of inhibitor, and watch for changes in the apparent Km.
Answer:
A pure substance has a constant composition and cannot be separated into simpler substances by physical means. There are two types of pure substances: elements and compounds. ... The ratio of the elements in a compound are always constant. (Water is always 11 % Hydrogen and 89 % oxygen).
