Amino acid catabolism involves the breakdown of 20 amino acids all of which contain nitrogen but have different carbon skeletons
Alex Ar [27]

Answer:

The overall strategy employed in the catabolism of the carbon skeletons of the 20 amino acids is conversion to citric acid intermediates such as acetyl-CoA

Explanation:

The breakdown of the  different carbon skeletons of the 20 amino acids is strategically channelled  towards the citric acid cycle. Six major products are obtained in the catabolism of the carbon chain of amino acids and these products all enter the citrc acid cycle. The six major products are acetyl-CoA, α-ketoglutarate, succinyl-CoA, fumarate, oxaloacetate and pyruvate.

The amino acids that are broken down completely into acetoacetyl-CoA and/or acetyl-CoA are said to be ketogenic since they yield ketone bodies in the liver.

The amino acids that are broken down into α-ketoglutarate, succinyl-CoA, fumarate, oxaloacetate and pyruvate can be converted to glucose and glycogen and are said to be glucogenic. Pyruvate can further be converted to either acetyl-CoA or oxaloacetate. Some amino acids though are both ketogenic and glucogenic, e.g. tryptophan, threonine.

What is the main difference bwtween prokaryotic and eukaryotic cells​
Ymorist [56]

Prokaryotic Cells = do not have a nucleus; generally smaller and simpler that Eukaryotic cells.

-Smaller

-does NOT have a Nucleus

-translates to ‘no Nucleus’ OR  ‘no true Nucleus’

-simpler

-they don't have all of their genetic material bound in a nucleus, which is why they are simpler forms of life.

-Prokaryotic cells do have genetic information but it is just stored differently

Ex: Bacteria and Single-Celled organisms

Eukaryotic Cells = Contains a Nucleus and are usually larger and more complex than a Prokaryotic cell

-Bigger

-DOES have a Nucleus

-More Complex

-Specialized to do certain things

Ex: All the Cells in a Human’s body. Skin cells, Red Blood cells
