Celulose. Some humans also cannot digest lactose aka someone who is lactose intolerant.
cellulose. humans do not possess the enzymes necessary for its digestion.
Cellulose is the substance found in plants that cannot be digested by cows due to their lack of necessary enzymes. It is a complex carbohydrate that provides structure to plant cell walls but passes through the cow's digestive system without being broken down, making it a source of dietary fiber.
Cellulose is a complex carbohydrate found in plant cell walls that cannot be digested by any mammal (including humans). This is because mammals lack the enzyme which breaks the β(1,4) linkages found within cellulose.
cellulose which is present in grass can be digested by ruminants but cannot be digested by humans
Fibers belong to the class of carbohydrates. They are a type of complex carbohydrate that cannot be fully broken down by the body's digestive enzymes.
Complex answer: Cellulose is a polysaccharide that provides structural support for plants. Humans cannot digest cellulose. Thus, you cannot digest wood, which is mostly cellulose. :Simple answer Humans cannot digest the carbohydrate cellulose. Soures:AP biology class, Textbook :3
Fiber
Starch cannot be used by the body until it has been digested because it is a complex carbohydrate made up of long chains of glucose molecules. The body lacks the enzymes needed to directly absorb these large molecules, so they must first be broken down into simpler sugars through the digestive process. Salivary amylase in the mouth and pancreatic amylase in the small intestine help convert starch into maltose and eventually into glucose, which can then be absorbed into the bloodstream and utilized for energy.
Enzymes are involved in the digestion of all types of foods except, of course, the foods that cannot be digested (like cellulose).
Dietary Fibre cannot be digested easily by human intestines because of lackness of enzymes.
True. Cellulose, a type of fiber found in plant cell walls, cannot be digested by humans because we lack the necessary enzymes to break it down.
Because it is in a form which is already digested e.g honey. Honey is already digested by bees so it is far more easier for the human digestive system to absorb.
