Explain why an increase in glycogen phosphorylase activity might result in an increase in O2 consumption in the cell.

Glycogen phosphorylase catalyses the rate limiting step in glycogenolysis, whereby muscle glycogen is broken down leading to the formation of glucose-6-phosphate and therefore sets the potential upper limit for glycolytic flux and increases in pyruvate availability
