Haemoglobin

Question 1

Structure

Answer 1

Found in red blood gells
Protein - Qautenery struxgure
Haem group with iron core
High affinity for oxygen, can carry 4 02 molecus

Question 2

Partial pressure

Answer 2

Is measure of 02 conc

Question 3

Dissociation curves

Answer 3

Haem has low affinity for o2 as first molecule binds making easier for 2&3rd to bind and has a higher affinty
3rd the haem becomes saturdated sheape changes so its hrder go binf

Question 4

Bohr effect

Answer 4

When cells respire they relase co3 and increases its concentration
Meaning hawm has mower affinity and low p02 Nd is more likley to dissociate
Curve goes right

Question 5

Curves

Answer 5

Curve shifted left= hugh affinity for oxygen
Advatangeous for libinh in hugh alititufes underground and foetus
Right- lower affiniry dissociation more
Small actige organisms
