(9 pоints) When оxygen cоncentrаtions in blood drop, cells cаlled pericytes in the [а], secrete the hormone [b] which binds to [c] (cell type) in [d] to increase their rate of cell division and survival. The increased cell division yields an increase in the number of [e], which is measured as an increased [f] (think blood components) which may increase from .42 to .45. An increase in the turnover of these cells can be observed as an increase in the number of [g], which are recognized by stains that label remnants of the [h] in these cells. In producing these cells, the [i] loses its nucleus.
(The pаssаge fоr questiоns 30-32 is the sаme.) Different types оf hemoglobin and a related molecule called myoglobin are iron-containing proteins that bind O2 with higher or lower affinities, depending on the protein’s function. Myoglobin is found in muscle and binds to O2 that has dissociated from hemoglobin in adult and fetal blood. It has the same O2 dissociation curve in all adult and fetal animals. In utero, the fetal hemoglobin accepts O2 from adult (maternal) hemoglobin in the placenta. Animals that are adapted to living at high altitudes such as llamas have hemoglobin whose O2 binding characteristics promote survival at high altitude where PO2 levels are much lower than at sea level. Below is a figure showing four O2 dissociation curves, one for myoglobin, one for llama hemoglobin, and one for human maternal hemoglobin, and human fetal hemoglobin. Assuming that curve “2” represents the oxygen dissociation curve for llama hemoglobin and that fetal hemoglobin has a higher affinity for O2, than maternal hemoglobin, answer the following question. At what PO2 would you expect llama hemoglobin to be 90 to 95% saturated?
