Question 1

How does bpg help o transport

Answer 1

Helps in conditions of low partial pressure by binding to deoxygenated hemoglobin and reducing its affinity for oxygen. When PP is low bpg levels inc. hemoglobin is also regulated by co2 to reduce affinity for oxygen .

Question 2

Discuss cooperative and allosteric

Answer 2

Coop- binding of substrate to enzyme effects binding of subsequent substrate molecules. It can either enhance or reduce binding.
Allosteric- molecule binds at a site other than the active site to induce conformational change in the enzyme that will enhance or inhibit activity
