When glucose level is high (above 90mg/100cm3), the brain sends impulses to the (β cells
of islets of Langerhans) pancrease cells; to release insulin hormone; the hormone stimulates
liver cells to convert the excess glucose into glycogen and fats for storage in the liver and
muscle cells; increases the oxidation of glucose in respiration to yield water energy and carbon
(IV) oxide/increases metabolism in the body; this leads to a fall in blood glucose to normal level;
However, when the glucose level falls below normal (below 90mg/100cm3); the brain sends
impulses to the (α cells of the islets of Langerhans) pancrease cells; which are stimulated
to release glucagon hormone; the hormone stimulates liver cells to convert the stored glycogen
and fats back to glucose; stimulates the conversion of amino acids to glucose; and stops the
oxidation of glucose in the body cells to avail more glucose; the glucose formed is released to
the bloodstream causing a rise of blood glucose level to normal;
The level of plasma proteins such as prothrombin, globulins, albumins and fibrinogen; which
play a major role in osmoregulation and blood clotting; are controlled by the liver; which
manufactures them using the amino acids found in the liver; when their levels reduce,more is
produced; but when the level is high, less of the proteins is produced in the liver; excess amino
acids are deaminated; as the body is not able to store them; the process involves removal of an
amino group from an amino acid molecule; the amino group enters the ornithine cycle; where
it is combined with carbon (IV) oxide to form urea; which is excreted in urine through the
kidneys;
