A: Humans are unable to digerst cellulose.
Explaination: Long story short, we lack the necessary enzymes since cellulose has a different structure than other carbohydrates that we are able to digest i.e. starches.
Salivary amylase is not able to digest cellulose. Amylase has the ability to digest starch but cellulose is a fibre which in indigestible.
Actually ruminants cannot digest cellulose, they have symbiotic bacteria in a part of their stomach called a "rumen" digest the cellulose down to sugars and starches that the ruminants can actually digest in another part of their stomach later.
Micro-organisms, such as bacteria, are able to digest cellulose. No mammals are able to digest cellulose. This is because cellulose contains a β(1,4) linkage that no mammalian enzyme can break. This is why herbivores must have symbiotic bacteria somewhere in their digestive system that help them break down cellulose.
People cannot digest cellulose
the appendix digest cellulose, but human appendix does not work.
Animals such as cows, horses, sheep, goats, and termites have symbiotic bacteria in the intestinal tract that contain the enzymes that allow them to digest cellulose in the GI tract. No vertebrate (animals with an internal skeleton) can digest cellulose directly; all must use the enzyme to break down cellulose.
None. Humans can't digest cellulose. Bacteria in the large intestine can digest some cellulose, creating gas and vitamin K.
None. Animals that can digest cellulose host special bacteria to digest the cellulose molecules, and humans do not host these.
