Proteins are large, organic biomolecules that consist of varying arrangements of amino acids linked together by peptide bonds. in which of the following cellular processes are proteins involved?

The correct answer is Translation or Protein biosynthesis.

Explanation:

Translation the end process of central dogma of molecular biology. Translation occur in cytoplasm in eukaryotes.During Translation process mRNA  binds with the 40S subunit of  ribosome. mRNA contain codons that interract with the anticodon of tRNA nad this codon anticodon interraction helps to code a  amino acid specific for that codon. For example AUG codes for methionine .

                     After encoding an amino acid ribosome moves to the next codon of mRNA and carry out the similar procedure to encode another amino acid that is then linked to its previous amino acid by peptide bond.

                  Thus the so formed amino acids are links with peptide bond and this continues till the ribosome recognizes a termination codon or non sense codon.

not sure if this what   you'r looking for would be percent composition

those characteristics are cellular organization, reproduction, metabolism, homeostasis, heredity, response to stimuli, growth and development, and adaptation through evolution. some things, such as a virus, demonstrate only a few of these characteristics and are, therefore, not alive
