(a) The partial pressure of oxygen in the alveoli is 13.3kPa. At this partial pressure of oxygen the
total volume of oxygen that is carried by 100 cm3 blood is 19.78 cm at pH 7.4 and 37°C.
The volume of oxygen that combines with haemoglobin at 13.3kPa is 19.48cm 100 cm 3
blood.

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.
