Which of the actions are beneficial functions of bacteria in the large intestine?

A. synthesize vitamins A and K

Bacteria is large intestine help in synthesizing Vitamin K, folate etc. These bacteria are also helpful in some of the undigested materials such as short chain fatty acids etc. This produces gas during digestion. pH is raised in small intestine by the action of bicarbonate from the bile juice from the gall bladder. Mucin is synthesized by gland cells of the body. Protein digestion takes place in stomach and duodenum.
