The working copy of the master blueprint is called messenger RNA (mRNA), whicÂ­h is copied from DNA.RNA, or messenger RNA, is generated by reading a strand of DNA. RNA polymerase (an enzyme that specifically makes mRNA) moves along the strand of DNA and joins complementary strands (in RNA, the complement to adenine is uracil instead of thymine). mRNA is produced only for the gene that is being read at that time.
Cellular Respiration: as organisms use food to make energy in the process of cellular respiration, carbon dioxide is produced. All types of biological molecules can be processed in cellular respiration to generate energy and, therefore, carbon dioxide.
Cellular respiration is not the same as breathing. Respiration is  just breathing in oxygen and breathing out carbon dioxide, but  cellular respiration is a chemical reactio â¦ n that uses oxygen and  glucose which gives the products carbon dioxide, water, and energy.1) Glycolysis. (2) Citric Acid cycle or Krebs Cycle. (3) Oxidative phosphorylation. The cell seems to respire in a way that it takes in molecular oxygen (as an electron acceptor) and releases carbon dioxide (as an end product), hence, the process is described to be aerobic.
