As both the genes get equally expressed in the human blood group genes, both the proteins or characters expressed by those genes get prominent in the phenotype of the organism.
<h3><u>
Explanation:</u></h3>
In case of human blood type, there are co dominance between the genes coding for A blood group and B blood group. Absence of both of them produce the O blood group and presence of both of them produce the AB blood group.
The gene for A blood group codes for enzyme α-1,3-N-acetylgalactosamine transferase which attaches the N Acetylgalactosamine to surface of RBCs which are actually the A antigens.
The gene for B blood group codes for α-1,3-galactosyl transferase which attaches galactose to surface of RBCs which are actually B antigens.
Presence of both of these genes make both N Acetylgalactosamine and galactose to be present on RBC membrane. This is why co dominance occurs in case of AB blood group persons.
Hormones glucagon and insulin are produced in the alpha and beta cells respectively in the Islet of Langerhan in the pancreas. They are involved in the negative feedback system of blood glucose regulation in homeostasis.
GLUCAGON: when there is a low blood glucose concentration, the pancreas detect this and alpha cells produce and release glucagon. Glucagon causes the cells of the body to absorb less glucose from the blood. It also inhibits the process of converting glucose into glycogen (glycogenesis) and cause gluconeogenesis (process of converting amino acids/proteins and lipids/fats into glucose) and glycogenolysis (conversion of glycogen to glucose). Finally, glucagon decreases the rate of respiration so less glucose is required.
INSULIN: when blood glucose is high, insulin is released. Insulin binds with cell surface receptors of cells and activates the enzymes attached to the receptor. The enzymes cause a conformational change in the structural proteins that surround glucose transport protein containing vesicles, causing them to move out of the way so the vesicles migrate up to the cell membrane and glucose transport proteins can fuse with it. Thus, more glucose can be taken in by cells. Insulin also cause glycogenesis (converting glucose into glycogen) and inhibits gluconeogenesis and glycogenolysis.
Basically insulin decreases blood glucose concentration (eg. after eating) and glucagon increases it (eg. skipping breakfast in the morning)
