Answer:

Maybe that your question is incomplete, in the options following the statement listed none is correct ...

The procedures would have the following order:

1-Propionyl-CoA is converted to Methylmalonyl-CoA thanks to the enzyme Porpionyl-Carboxylase CoA which adheres to a carboxyl modifying the chemical structure (This enzyme depends on ATP, biotin and bicarbonate, to carry out the reaction).

2-Then, Methylmelanolyl-CoA is adhered to a radical, thanks to the enzyme methylmalonyl-CoA racemase, thus generating (R) -methylmalonyl-CoA as a product of the reaction.

3- And finally, (R) -methylmalonyl-CoA is converted to succinyl-CoA, an intermediate of the tricarboxylic acid cycle, by the enzyme methylmalonyl-CoA mutase, which requires cobalamin to catalyze carbon-carbon bond migration.

4-The mechanism of the methylmalonyl-CoA mutase begins with the cleavage of the bond between the 5 'of CH2-5'-deoxyadenosyl and cobalt, which is in its 3 + (III) oxidation state, which produces a 5'-radical. deoxyadenosil and cabalamin in the state of reduced oxidation Co (II)

Explanation:

Propionyl-CoA is important to know that it can come from different biological rations of the organism, such as: beta oxidation (of odd-chain fatty acids), the metabolism of isoleucine and valine and As a product of α-ketobutyric acid, which in turn it is a product of the metabolism of threonine and methionine.

The result shows that the microorganism is Staphylococcus aureus.

<h3>How to explain the microorganism?</h3>

Blood Agar media shows colonies which means the microbe must be a fastidious one. It allows bacteria to be distinguished by the type of hemolysis they produce. Here in the image, beta hemolysis is depicted.

Gram staining depicts a gram-positive coccus. Gram-positive organisms take up crystal violet dye and are stained purple while gram-negative organisms take up the safranin dye and give pink to red colonies.

Catalase protects the organisms from reactive oxygen species and Coagulase. According to the above results, the microorganism is Staphylococcus aureus.
