The urea cycle involves the transportation of which enzyme via the mitochondria into urine ? |
AMMONIA |
|
|
Urea cycle begins where ? |
The urea cycle begins within the mitochondrial matrix of the cell. |
|
|
In step 1 the enzyme that catalyses this step of the urea cycle ? |
Carbomoyl phosphate synthatase |
|
|
CO2 is formed via the Biocarbonate but requires ATP to produce what ? |
Carboxyphosphate |
|
|
The carbomoyl phosphate releases ammonia as substrate and requires second ATP for Carbonic acid to produce ? |
Carbomoyl phosphate which is the first amino group. |
|
|
But the carbomoyl phosphate synthatase can only be activated via what ? |
N - acetyl glutamate |
|
|
The Carbomy phosphate then kicked off to make Ornithine catalysed by what? |
Ornitihine transcarbamylase that makes Citrulline. |
|
|
The Citrulline moves into what part of the cell ? |
Cytoplasm of the cell. |
|
|
The second amino group made is ? |
Asparate needed to transfer H3N from asparate |
|
|
Asparate to form Argininosuccinate is made possible by which enzyme? |
Argininosuccinate synthatase whcih uses both ATP - AMP and PPI pyrophosphate. |
|
|
Arginosuccinate then reacts with Arginosuccinase to release carbon skeleton and make |
Arginine and Fumerate has a link with gluconeogenesis to form glucose. |
|
|
The Arginine formed from previous step of the enzyme reacts via Arginase a water molecule to attack + hydrolise and forms what? |
Ornithine that enters the urea. |
|
|
Name the 2 amino groups essential for the urea cycle ? |
Carbomyol phosphate Asparate |
