Amino Acid metabolism

Question 1

Is Amino Acid Metabolism a perfered source for energy?

Answer 1

NOOOOO

Question 2

When would amino acid be used to make ATP?

Answer 2

if glucose and lipid supplies are very small

Question 3

What needs to happen before amino acid can be used to make ATP?

Answer 3

the amine group on amino acid needs to be changed in order to be used

Question 4

names of 2 processes that prepare amino acid to be used for metabolism

Answer 4

1.Transamination
2.Deamination

Question 5

How does transamination change the amino group?

Answer 5

mitochondria attaches amino group to a keto acid instead of an amino acid

Question 6

How does deamination change the amino group?

Answer 6

cells in liver REMOVE amino group and a H ion which creates a product that can be used AND an ammonion ion. That ammonion ion gets converted to Urea by liver.

Question 7

What is the goal of both transamination and deamination?

Answer 7

get amino acid ready to make ATP

Question 8

3 reasons amino acid metabolism is an impractical source of quick energy?

Answer 8

1. more difficult to break apart than carbs or lipids
   2.one of the by products of deamination (Ammonion ion) is toxic
   3.amino acids are used for other things and overuse of them can threaten homeostasis.
