Tek 11B - enrichment question
By Tanya Raghu
If the bacteria in a human's stomach that helps break down food is being killed off, how will that affect the human's digestive system?
Simple carbs (glucose) can easily be broken down by the body to make easy ATP energy, ready to use
Complex carbs (starch and cellulose) take more effort and first must be broken down into simple sugars before they can be processed. Special enzymes called CAZymes start breaking them into simple carbs to easily be digested.
Bacteria in the Gut
This is the biggest digesting organ where most food gets broken down. The gut houses many CAZ enzymes which break the complex carbs and also cellulose which is found in the cell walls of plants. Many bacteria have the ability to make cellulosome which is a large complex system of cellulose breaking enzymes held together by proteins.
