Hi everyone. Welcome back. Let's look at our next question. It says which of the following biomolecules is digested in the sick um of herbivores? Well let's recall that herbivores of course have a plant based diet and as a result their diet is very high in cellulose. Now, herbivores just like humans don't produce naturally. The enzyme is necessary to digest cellulose. And so humans don't digest cellulose at all. It passes through our system. But it actually that's okay. It serves an important role as fiber in our diet helping food to pass through the digestive system. But herbivores, since they depend completely on plants um have the sick um that allows them to digest cellulose. And let's recall from our content video that that is because the sick um which is. This pouch between the small and large intestines contains bacteria that have the enzymes necessary to digest cellulose. So after the food passes through the small intestine, you have this pouch of the sick um with the bacteria that break down the cellulose since they produce that enzyme. And then the materials from the breakdown of cellulose can be passed along to the large intestine and absorbed. So we look at our answer choices here we see that choice B. Is cellulose. So that's going to be our answer. The other answer choices here. A starch, c lactose and sucrose. Um Are all carbohydrates that can be digested and absorbed in the small intestine. So they're not the correct answer. But the bio molecule that's digested in the system of our divorce is choice be cellulose. See you in the next video.
