Most organisms make ATP using glucose and oxygen during the process of cellular respiration. Which is the MOST LIKELY explanation for what prevents Earth from running out of oxygen? - Photosynthesis generates oxygen
- Cellular Respiration doesn't account for that much oxygen use
- Oxygen is available deep in the ocean at hydrothermal vents
- All of the above

The empty trna moves off and picks up another matching amino acid from the cytoplasm in the cell. the anticodon of the trna, with its attached amino acid, pairs to the codon of the mrna, which is attached to a ribosome. this sequence is repeated until the ribosome reaches a stop codon on the mrna, which signals the end of protein synthesis. the ribosome forms a peptide bond between the amino acids, and an amino acid chain begins to form. when a second trna with its specific amino acid pairs to the next codon in sequence, the attached amino acid breaks from the first trna and is bonded to the amino acid of the second trna.
