Question

During Arjun's infection, S. pyogenes was growing in two very different environments-on the surface of his skin and in the deeper tissue. Explain the metabolic pathways S. pyogenes would use in each of these environments and why.

Answer 1

Use Phosphotransferase system where glucose is not available.

Step-by-step explanation:

Streptococcus pyogenes uses its phosphotransferase system for the uptake and metabolism of non-glucose carbohydrate sources in the environment where glucose is not available. Streptococcus pyogenes also uses malate which is a dicarboxylic organic acid that is present in large amount in both tissue and in the external environment. This malate is a non-glucose carbohydrate source used by Streptococcus pyogenes for the production of energy.
