The Bohr effect describes a relationship between haemoglobin, oxygen and carbon dioxide.
In low partial pressure of oxygen and high partial pressure of carbon dioxide, the affinity of haemoglobin for oxygen decreases.
In high partial pressure of oxygen and high partial pressure of carbon dioxide, the affinity of haemoglobin for oxygen increases.
In low partial pressure of oxygen and low partial pressure of carbon dioxide, the affinity of haemoglobin for oxygen is unchanged.
In high partial pressure of oxygen and low partial pressure of carbon dioxide, the affinity of haemoglobin for oxygen decreases.
Which of the following statement is NOT correct.
X have more oxygen content than Y
Y have more carbon dioxde than X
X have more glucose than Y
Y has higher pressure than X
Which of the following is NOT correct about haemoglobin.
It has haem group that combines with oxygen.
the outside is hydrophilic and the inside is hydrophobic - this allows the shape to be globular
it has 3 haem groups that can combine to 8 oxygen atoms
the shape changes after combining with the first oxygen molecule so that it's easier for the other oxygen molecules to join in.
Which of the following is not a white blood cell?
neutrophil
leukocyte
erythrocyte
monocyte
Which cell arrives at the 'crime scene' first?
