What happens to the broken down parts of
the pathogen engulfed by the phagocyte?

It  digests the ingested particle with hydrolytic enzymes (whatever that is) which are contained within membrane-enclosed sacs called lysosomes found within the cell. And then Phagocytic enzymes are secreted into the vacuole in which digestion takes place

Explanation:

Hope this helps u and im not wrong

both anaerobic and aerobic respiration use glucose (or other carbohydrates), proteins and lipids to produce atp and nadh. cell uses those energy molecules, obtained from food and   breaks them down during the chemical reactions of respiration. in anaerobic respiration, nadh is regenerated to nad+ by enzymes lactate dehydrogenase (lactate is produced, e.g. in muscle cells) or by alcohol dehydrogenase where ethanol is produced (alcohol fermentation), while in aerobic respiration, electrons from nadh are deposited in the mitochondria to regenerate nad+ (electron transport chain. anaerobic respiration produces 2 atp per molecule of glucose compared to aerobic respiration where about 38 atp molecules are produced.

substitution is the answer in this case
