If haemoglobin is low in blood, which problem may increase in the body?
Answer and explanation
Correct answer: Reduced oxygen transport
Haemoglobin is the iron-containing pigment in red blood cells that binds oxygen in the lungs and transports it to body tissues. If haemoglobin concentration falls, the blood carries less oxygen, so cells may receive insufficient oxygen for respiration; tiredness and weakness can result. Option A is correct. Taste, starch production and stomatal opening are unrelated to haemoglobin-dependent oxygen transport in humans.
