Question

The release of oxygen by haemoglobin for use in body tissues is dependent on all of the following

• A. low $P{O}_2$ of body tissue cells
• B. alkaline pH of blood in tissue capillaries
• C. presence of ATP
• D. all of the above cause the release of oxygen from haemoglobin

Answer 1

The correct option is A low $P{O}_2$ of body tissue cells

The release of oxygen by hemoglobin for use in body tissues is dependent on the low partial pressure of oxygen in tissue.

So, the correct option is 'low

PO$_2$PO2of body tissue cells'.
