Here's the answer to #1: Enzymes are proteins that act as catalysts, they speed the rate of some chemical reactions. But they only act within a narrow range of temperature and pH, so an excessively high body temperature will slow down or completely stop the reaction. 2 Days later: No one seems to have responded on the other questions, so here's #2 and 3#: Nucleic acids are long chains of nucleotides with phosphate esters linking them together.

The second part of the question asks the two major classes. I assume that to mean the two types, which are purine and pyrimidine bases. Three-dimensionally, they form a single or double-stranded helix structure.

I'm not sure how to compare and contrast them structurally. In genetics, the nucleic acids can vary in individual proteins, so they are often the determining factor in the characteristics of the protein, whether they are beneficial or disease-causing. The central role of ATP in the body is to be the source of high-energy phosphate to power reactions in the cells.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
