The amount of oxygen released from hemoglobin in systemic circulation
SATA:

1 increases as blood pressure increases

2 increases as the PCO^2 in the tissues increases

3 decreases as body temperature decreases

4 is dependent upon the tissue level of metabolic activity under normal conditions

5 increases as blood becomes more acidic

Answer #1

4 is dependent upon the tissue level of metabolic activity under normal conditions.

The amount of oxygen needed is directly proportional to the amount of oxygen released from the haemoglobin as the the release depends upon the need. The muscles and tissues doing stranous activities needs more oxygen for their metabolism and energy production. So more oxygen will be delivered to the the tissues which are under high stranous activities.

    For the video response portion of this assignment, your job will be to state what would happen to the oxygen bond to Hemoglobin if the pH of the tissue was the same as that of the lungs using the logic of the person’s presentation you watched. Discuss whether or not you agree with this. The video said this: Oxygen must be transported in the blood from the lungs, because the partial pressure of oxygen (pO2) is relatively high (approximately 100...

    Heme is the iron-containing structure in the proteins hemoglobin and myoglobin. In red blood cells, hemoglobin enables oxygen uptake and transport. Myoglobin in muscle cells helps oxygen enter the cells. The oxygen carried by hemoglobin and myoglobin is critical for energy production. Because meat contains hemoglobin and myoglobin, beef, fish, and poultry contain more heme iron than most plant foods. The remaining iron in meat, as well as all the iron in vegetables, grains, dietary supplements, and fortified or enriched...
