Neco 2019 Biology Question 14
Practice objective / multiple choice question 14 from the 2019 Neco Biology examination.
At sea level a person has a haemoglobin concentration of 150 g L\(^{-1}\); each gram of haemoglobin binds 1.34 mL O\(_2\). After acclimatisation to high altitude the haemoglobin concentration rises by 15 % and the arterial PO\(_2\) increases from 100 mmHg to 110 mmHg. Dissolved O\(_2\) in plasma changes by 0.003 mL O\(_2\) per mmHg per litre of blood. Calculate the increase in total O\(_2\) content (bound + dissolved) per litre of blood, in mL O\(_2\).
