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.
Photosynthesis uses water, sunlight, and carbon dioxide from the atmosphere to create glucose molecules, and releases oxygen as a by-product. Cellular respiration uses glucose molecules and oxygen to produce ATP molecules and carbon dioxide as the by-product. Photosynthesis takes place only when there is sunlight. Cellular respiration occurs at all times. Photosynthesis involves conversion of one type of energy into another: light energy into chemical energy. Cellular respiration involves using that chemical energy and breaking it down to release energy.
