The Liver in Excretion

Question 1

what does the liver excrete? though what is it more of than excretory

Answer 1

ammonia/urea, dead RBC, more of a creator

Question 2

Why are proteins that are entered into the liver broken down and what are they broken into

Answer 2

because excess protein can’t be stored, broken into amino acids

Question 3

What can broken down amino acids be used for

Answer 3

• make new proteins

- lost from body via urine, sweat

Question 4

Explain deamination in the liver

Answer 4

1) amino group (NH2) in amino acid is removed
2) once removed,the NH2 is converted to ammonia (NH4)
3) its then converted to urea(as less toxic), an eliminated in urine (by adding energy and CO2 to make urea and water)
4) remaining part of amino acid(primarily hydrogen + oxygen)= converted to carbohydrate, which is readily broken down by cells to release energy, water and carbon dioxide

Question 5

What is the first formula in Deamination

Answer 5

Amino acid + oxygen = carbohydrate + ammonia

Question 6

What is the second formula in Deamination

Answer 6

Energy + carbon dioxide + ammonia = urea + water

Question 7

What happens to the remainder of the amino acid after the amino group is removed

Answer 7

As made of carbon and hydrogen, turned into a carbohydrate that can be readily broken down by cells to release energy carbon dioxide and water
