Question 16
(a) What is haemoglobin? (b) Describe ONE adaptive advantage of haemoglobin.
Worked Solution & Example Answer:(a) What is haemoglobin? (b) Describe ONE adaptive advantage of haemoglobin. - HSC - SSCE Biology - Question 16 - 2006 - Paper 1
Step 1
What is haemoglobin?
Answer
Haemoglobin is a complex iron-containing protein found in red blood cells. Its primary function is to transport oxygen from the lungs to the tissues and return carbon dioxide from the tissues back to the lungs. The structure of haemoglobin enables it to bind oxygen efficiently, allowing for effective gas exchange in the body.
Step 2
Describe ONE adaptive advantage of haemoglobin.
Answer
One adaptive advantage of haemoglobin is its ability to increase the oxygen-carrying capacity of blood. This is particularly beneficial for organisms that require high levels of oxygen for metabolism, such as those that are active or have high energy demands. By efficiently transporting oxygen, haemoglobin enhances aerobic respiration, allowing for better energy production in cells.
