Answer: D) By decreasing the activation energy of a reaction
A catalyst is a substance that speed up the rate of chemical reaction without affecting the product of the reaction. They only affect the rate of reaction not the yield of reaction.
Catalyst provide an alternative reaction pathway that has lower activation energy than that of uncatalysed reaction. It increases the frequency of collision and because of these greater collision which lowers the activation energy of the reaction.
Answer:
idk but good luck i hope you get it right
Explanation:
5-fold 10-fold 2-fold 2.5-fold IgG has the same avidity as the IgM.compared to the igg assuming that both the isotopes have the same affinity
The Isotopes are the members of the family of an element that all have the same number of the protons but the different numbers of the neutrons. The number of the protons in the nucleus that determines the element's of atomic number on the Periodic Table. For example, carbon has the six protons and is atomic number 6.
Radioactive are isotopes have many useful applications. In the medicine, for example, cobalt-60 is the extensively employed as the radiation source to arrest the development of the cancer. Other radioactive isotopes are also used as tracers for the diagnostic purposes as well as in the research on the metabolic processes.

Answer:
Allosteric enzymes bind at different site from the substrate binding site.
Explanation:
The activities of some enzymes, particularly those which form a part of a chain of reactions like metabolic pathways, are regulated internally. Some specific low molecular weight substances such as the products of another enzyme further on in the chain, acts as the inhibitor. Such a modulator substance binds with a specific site of the enzyme different from the substrate binding site. This binding increases or decreases the enzyme action. Such enzymes are called allosteric enzymes and the site at which they bind is called allosteric site.
Example: Hexokinase is an enzymes which converts glucose to glucose-6-phosphate in glycolysis. Decline in the enzyme activity by the allosteric effect of the product is called feedback mechanism, like the allosteric inhibition of hexokinase by glucose-6-phosphate,
