Please choose the correct ending to complete the given sentence: Education and Communications: [header] How to learn and understand the chemistry and physiology of enzymes in humans [title] Learn what are enzymes and how they are synthesized in the body. [step] Enzymes are a class of proteins that have special functions in the body of living organisms including human individuals. These enzymes are synthesized in the body by the same mechanism of proteins translational processes that involves the coding of amino acids by codons that are comprised each of three dna bases.

Ending1: Each codon of three neighboring dna bases codes for one amino acid. This amino acid is in turn transported to the cellular ribosome using special type of rna molecule that is called transfer rna molecule. Ending2: A molecular environment usually has good biology of their own, the slow enzymes (bmi) are avowable for humans. They are synthesized first in the laboratory, as them. Ending3: For example, mna is a chemical derived from the core of amino acids. This chemical is then released in everyday life. Ending4: They are injected into the genital area of the body. [title] Study how our bodies behave in our atmosphere.
