Given statement is true that bile juice does not contain any digestive enzymes, yet it is essential for digestion.
Bile juice helps in the digestion of fats and lipids in an indirect way. When fats reach the small intestine, digestive enzymes are not able to act upon them because of their large globular size. So, the role of bile juice comes into existence over here. They break those large globular fat molecules into small molecules and this process is known as emulsification of fats. As, the large globular fat molecules are converted into small fat molecules digestive enzymes can now act on the fat globules and digestion of fats take place.
Therefore, bile juice helps in the digestion by the process of emulsification.
