The genetic code can be defined as a set of rules used to encode information from genetic material (DNA or RNA ) into proteins. There are sequences of nucleotide triplets, -codons which specify which amino acid will be added next during translation (protein synthesis). Genetic code consists of 64 codons and this means that some amino acids are specified by more than one codon.

Genetic code has a role to determine amino acid sequence of protein (primary structure of protein). Location and the function of all those synthesized proteins is determinated by regulatory genomic regions (gene regulatory codes).

Proteins perform a wide range of functions within organisms such as catalysing metabolic reactions, DNA replication, stimuli response, structure role, transport role. So, all the diversity of organisms on this planet is due to protein variety.

Microbes that thrive in acidic environments seem to have "cost free" ATP energy available to them due to the pre-existing H grad
bixtya [17]

Answer:

The microbes thriving in acidic environments are termed as acidophiles, and these range from eukaryotes to bacteria and archaea, which are mainly found in diverse acidic surroundings like sulfuric geysers and pools, in the human stomach, and in the regions that get polluted by acid mine drainage.  

The mentioned case is not entirely correct as the protons found in the acidic surroundings are not utilized for the generation of ATP as they are not originating from within the cell. In order to sustain their internal acidic pH, the acidophiles exhibit adaptations like the presence of the negatively charged proteins on the surfaces of their membranes so that they can prevent deterioration due to acidic surroundings.
