The polysaccharide cellulose is not digestible by humans, as we lack the enzyme cellulase, which is required to break it down. Certain dietary supplements contain the enzyme cellulase and claim that being able to break down cellulose will help a person lose weight. But what do you think would happen if we could digest the cellulose we ate?

Hey, everyone. Let's take a look at this question together in cows, which chamber serves as the primary site or cellulose digestion. Is it answer choice? A the sem answer choice B the rumen answer choice C, the large intestine or answer choice D abomasum, let's work this problem out together to try to figure out which of the following answer. Choices is the chamber in cows that serves as the primary site for cellulose digestion. So in order to solve this question, we have to recall what each of the following chambers is responsible for and what chamber serves as that primary site for cellulose digestion. Well, answer choice A which says the sem, we know that the sea which is part of the large intestine is responsible for fermentation and digestion of certain nutrients. And since it is a part of the large intestine answer choice C which says large intestine is responsible for water absorption and certain nutrient reabsorption. And lastly answer choice D which is the abomasum is the fourth compartment of the stomach in cows and is responsible for protein digestion. So since answer choice, A, the SCU answer choice C, the large intestine and answer choice. D the abomasum are not the primary site for cellulose digestion in cows. They are all incorrect and answer choice B the rumen is the correct answer since the rumen is the chamber in cows that serves as the primary site for cellulose digestion. I hope you found this video to be helpful. Thank you and goodbye.
