Natasha is making a model of cellular respiration. Her model shows the pathway followed when there is enough oxygen available. What does Natasha’s model show?

An aerobic pathway consisting of glycolysis, the Krebs cycle, and the electron transport chain

Explanation:

It's aerobic because oxygen is available while anaerobic means that no oxygen is present.

Hope it helps :)
