Haemoglobin, a substance in human blood, transports oxygen from the lungs to the rest of the body. With each oxygen molecule it picks up, a haemoglobin molecule becomes more effective at picking up additional oxygen molecules until its maximum capacity of four oxygen molecules is reached. Grabbing an oxygen molecule changes the shape of the haemoglobin molecule, each time causing it literally to open itself to receive more oxygen.
Which one of the following is most strongly supported by the information above?
A haemoglobin molecule that has picked up three oxygen molecules will probably acquire a fourth oxygen molecule.
No evidence from the question stem exists to support this
B. The only factor determining how effective a hemoglobin molecule is at picking up oxygen molecules is how open the shape of that hemoglobin molecule is.
Does not mention that the shape is the only factory. B is out
C. A hemoglobin molecule that has picked up three oxygen molecules will be more effective
