120 is a normal glucose level for an average human, in fact anything between 80-120 is considered normal. However because 120 is in the higher reaches your body may attempt to keep it below that so it would produce only a small amount of insulin.
Answer:
Lactase and Carbonic anhydrase are enzymes;These are organic catalyst (proteins) that speed up the rate of organic chemical reactions,in living organism.They acts on the organic reactions by reducing the activation energy for the reaction to occur,but remain unchanged at the end of the reaction.
Explanation:
Lactose is an enzyme in the small intestine needed for the break down of Lactose,a diasaccharides to glucose and galactose.it is acts in the brush borders for this to occur.
Carbonic anhydrase is an enzyme in the cytoplasm needed for the the catalysis of C02 with H20 to form Carbonic acid(H2CO3),protons, and hydrogen carbonate in a reversible reactions.
The catalysis is needed for regulation of blood pH during respiration.
As stated up,molecules of catalyst do not change in the organic chemcial raxction they act upon.Rather they lower the activation energy for the faster completion of the rate of reaction.
Therefore in the question above the amount of the catalayst will remain the same it was at the beginning of the reaction.This is the major properties of catalysts.
Answer: DNA has thymine as one of the two pyrimidines while MRNA has uracil as its pyrimidines base.
