In order to use amino acids as fuel, ____________ must occur. This process results in the formation of a(n) ____________ .
kaheart [24]

In order to use amino acids as fuels, amino acid metabolism must occur. This process results in the formation of 2-oxo-acids.

<h3>What is amino acid metabolism? </h3>

The excess proteins/amino acids in the body are to be broken down or catabolized as there is no mechanism for the storage of amino acids in the human body. Different amino acids have different mechanisms of catabolism.

Based on their catabolism process, amino acids are categorized into two types.

1. Glucogenic amino acids - The amino acids which can be converted into glucose, pyruvate, and intermediates of the TCA cycle are called Glucogenic amino acids. These intermediates are converted to 2-oxo-acids.

2. Ketogenic amino acids - These are either converted to fat, Acetyl CoA, or AcetoacetylCoA. These condense with 2-oxo-acids and the net gain is zero.

Therefore, amino acid metabolism results in the formation of 2-oxo-acids.

Discuss 2 ways in which efforts to protect species can lead to controversy
Crazy boy [7]

Protection of certain species is a very controversial topic. Many species like the mountain lion or jaguar that are near extinction in certain areas, are threats to human life. Another reason is that they could off set the food chain when they come back and be stonger than ever. For example the mountian lion could eat out the thriving white tail deer population which was struggling because of the mountain lion. And many people rely on white tail deer for food.

Hope this helped :)
