2. Divide vehicle operation costs, $293.83 per month in our hypothetical scenario, by the distance you drive per month, 750 miles (1,207 km) in our example, to calculate the cost per mile. The cost per mile for this hypothetical driver and vehicle is 39.17 cents per mile or 24 cents per kilometer.
The digestive juices are a team of powerful enzymes produced by the mouth, stomach and small intestine that break down the three major types of nutrients into their constituent parts so that they become absorbable by the body.
Many of these foods contain both starch, which can be digested, and fiber, which the body cannot digest. The digestible carbohydrates are broken into simpler molecules by enzymes in the saliva, in juice produced by the pancreas, and in the lining of the small intestine.roduction of Digestive Juices The glands that act first are in the mouth--the salivary glands. Saliva produced by these glands contains an enzyme that begins to digest the starch from food into smaller molecules. The next set of digestive glands is in the stomach lining.
