Cells in your body work together, they form bones, and muscles. Cells, however cannot work alone, they must be able to work together. Each cell does a different thing.
Answer;
-On the polar end or the hydrophillic end of the protein.
Explanation;
-Each amino acid has at least one amine and one acid functional group as the name implies. The different properties result from variations in the structures of different R groups.The R group is often referred to as the amino acid side chain.
-Side chains which have various functional groups such as acids, amides, alcohols, and Amines will impart a more polar character to the amino acid. Polar amino acids include serine, threonine, asparagine, glutamine, histidine and tyrosine.
Therefore; serine being a polar or hydrophillic amino acid will be found on the polar side chain of the protein.
The answer is; catalyst
These proteins are called enzymes. They work by lowering the activation energy of reactants and hence speed up the biochemical reaction. They are not affected in the process hence one enzyme molecule can catalyze many reactions. An example of such an enzyme is carbonic anhydrase that enables carbon dioxide to dissolve in blood plasma as carbonic acid.
The best way of doing it without potentially causing harm to yourself, would be "wafting".
