Deficiency of this mineral leads to delayed wound healing, hypogonadism, and loss of adult (axillary, facial, pubic) hair. A patient has chronic obstructive pulmonary disease, enough oxygen is not reaching her tissues. c) is activated by the hormone insulin. Glucokinase and Hexokinase are enzymes which phosphorylate glucose to glucose-6-phosphate, trapping glucose inside the cell. Glucokinase is present in hepatocytes of the liver and beta cells of pancreas, tissues that needs to quickly respond to changes in glucose levels. Insulin Synthesis And Secretion. Definition. Clinical picture is similar to that described in CHI with mild manifestations leading to a delay in diagnosis until adulthood.
