2. Different Types Of Haemoglobin

Question 1

What causes different types of haemoglobin ?

Answer 1

Where they live

How active they are

Their size

Adapted to the haemoglobin they have as helps organism survive in particular environment

Question 2

Low oxygen environments

Answer 2

High affinity for oxygen (compared to humans)
As not much o2 avaiavlvle.
Haemoglobin is good at loading oxygen on.

(Underground/ high altitudes)

Question 3

Example of low energy environment

Answer 3

Lug worm
Sand
Low conc of o2
Haemoglobin has high affinity to pic up o2 that’s available quickly

Question 4

High activity levels

Answer 4

Very active
High oxygen demand
Low affinity
Need o2 to easily unload so it’s available for them to use.

Question 5

Right on graph …

Answer 5

High respiration rate

Question 6

Example of high activity levels

Answer 6

Hawk
High respiratory rate
As it’s activity and lives where’s there plenty of o2
Unload quickly In order to meet high oxygen demand
Low affinity for o2

Question 7

Small animals

Answer 7

Large SA: volume 
Lose heat quick 
High metabolic rate to keep warm 
High o2 demand 
Low affinity for o2 than humans because they need their haemoglobin to easily unload to meet high o2 demand. 
RIGHT OF HUMAN

Question 8

Example of small animal

Answer 8

Rate
High SA: volume
Unload easily to meet greater o2 demand
Low affinity

Question 9

Higher metabolic rate =

Answer 9

Higher respiration rate

High o2 demand

Low affinity
