Answer:

The endosymbiotic theory states that some of the organelles in today's eukaryotic cells were once prokaryotic microbes. In this theory, the first eukaryotic cell was probably an amoeba-like cell that got nutrients by phagocytosis and contained a nucleus that formed when a piece of the cytoplasmic membrane pinched off around the chromosomes. Some of these amoeba-like organisms ingested prokaryotic cells that then survived within the organism and developed a symbiotic relationship. Mitochondria formed when bacteria capable of aerobic respiration were ingested; chloroplasts formed when photosynthetic bacteria were ingested. They eventually lost their cell wall and much of their DNA because they were not of benefit within the host cell. Mitochondria and chloroplasts cannot grow outside their host cell.

There are numerous number of enzymes involved in the digestion of the food released by various organs. The pancreatic and intestinal enzymes are secreted that work at alkaline pH, but the chyme that is secreted from the deodenum is slightly acidic yet they work together.

This is because pancreas pour enzyme into small intestine which is alkaline  and it then secretes huge amount of sodium bicarbonate which neutralizes the acidity of the stomach and makes the pH optimum for the digestion of food.
