- explain why the maintenance of a constant internal environment is important for optimal metabolic efficiency
- explain the adaptive advantage of haemoglobin
- describe the main changes in the chemical composition of the blood as it moves around the body and identify tissues
In which these changes occur

tl;dr from the top of my head:

1. Enzymes work best under optimum conditions like temp and pH. If they are any variations it'll reduce their rate of activity. Large variations will denature the enzyme (it'll be permanently damaged and won't be able to catalyse reactions). As you learnt in your first dot point, you should know why enzymes are important so we need to maintain a constant internal environment.

2. Each haeomoglobin molecule contains 4 actives sites where oxygen molecules can be attached and each rbc contains 280-300 million haemoglobin. So the advantage here is pretty clear, it allows mammals to transport more oxygen to the tissues.

3. idk i cbf turning on my laptop ^^"
