Answer:
b) glycolisis
Explanation:
Glycolisis precedes the Krebs cycle and can take place under aerobic or anaerobic conditions. Under aerobic condition, energy is directed towards the Krebs cycle in the form of piruvate and NADH to create more ATP. Under anaerobic conditions piruvate does not enter the Krebs cycle and it is oxidized to produce lactate.

The phagocytes have the ability to ingest the pathogen by engulfing it.
