Deanimation

Question 1

Deanimation

Answer 1

The deconstruction of A.A

The chemical deconstruction produces NH2 (ammonia) and can be used to create energy

Removes amine

Question 2

Why deamination occurs

Answer 2

It creates energy, when old proteins cannot longer serve its function

Question 3

Excretion

Answer 3

The ammonia (toxic to cells) is broken down into urea (non toxic) and is removed through kidneys

Urea enters the blood where it is filtered out by the kidneys for urination and small amounts via the skin

Question 4

Steps of excretion

Answer 4

Step 1 : removal of ammonia

A.A + Oxygen >(enzymes)> Carbohydrate + A.A

Steps 2 : breaking down ammonia to urea

Energy + Co2 + Ammonia > Urea + H2O

Question 5

Flow chart of deanimation

Answer 5

Old protein

Breakdown of A.A

Breakdown of A.A using ATP + Co2 into urea

Remove amine > produces ammonia, glucose, Co2, acetyl CoA, H2O, ketone bodies

Filtered by kidneys
