__**Proteins as Enzymes in a Cell**__

__What is a protein?__ A protein (also known as a polypeptide) are organic compounds composed of long string of amino acids. A protein is a macromolecule. The sequence of amino acids in a protein is determined by the genetic sequencing the genetic code. Proteins take part in almost every function in a cell. Proteins can catalyze (speed up) biochemical reactions, which is vital to metabolism

__Synthesis of Protein__ Protein synthesis begins in the DNA. The DNA "unzips" and messenger RNA transcribes the coding. The RNA then carries the protein information to the ribosome, where the amino acids are formed. The ribosome reads the nucleotides 3 at a time. When one part of the molecule is formed, the next 3 nucleotides are read, another part of the molecule is formed, attachting
