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.

Use Phosphotransferase system where glucose is not available.

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.
