A specific enzyme catalyzes only a specific substrate. Another name for starch is "amylose". So amylase catalyzes amylose. Just like lactase catalyzes lactose. For people who are lactose intolerant, their bodies don't, or in small quantities, produce lactase, so it doesn't get digested. So, only the enzyme "cellulase" will catalyze the hydrolysis of "cellulose".
Starch
No. Cellulose and starch are both forms of carbohydrates, not a form of one another.
The monomer that makes up glycogen starch and cellulose is the monasaccharide?
Two polymers made by plants are cellulose and starch. Cellulose is a structural polymer that provides strength and rigidity to plant cell walls, while starch is a storage polymer that serves as a source of energy for plants.
The first catabolite produced from the catabolism of starch and cellulose is glucose. Both starch and cellulose are polysaccharides composed of glucose monomers, and they are broken down by enzymes like amylase (for starch) and cellulase (for cellulose) into glucose units. This glucose can then be further metabolized for energy or converted into other compounds.
No, starch is easier to digest.
Humans can digest starch because they produce an enzyme called amylase that can break down starch into simpler sugars. However, humans lack the enzyme needed to break down cellulose, which is a complex carbohydrate found in plant cell walls. This is why humans cannot digest cellulose.
Salivary amylase is not able to digest cellulose. Amylase has the ability to digest starch but cellulose is a fibre which in indigestible.
FALSE! I think (•_•)
Hm... (first time answering a question on here) Well, you can digest bread because it is made of grains. Bread is a starch polysaccharide and is, therefore, made of carbohydrates. Paper is made of cellulose and nothing in the world can digest cellulose so... yeah... 0w0"
Cellulose is a type of dietary fiber found in plant cell walls that humans cannot digest. Glycogen is a form of stored glucose in animals, while sucrose and starch are forms of carbohydrates that can be broken down by the body for energy.
People cannot digest cellulose
Starch
No. Cellulose and starch are both forms of carbohydrates, not a form of one another.
Oh, dude, like, starch and cellulose are both polysaccharides, but our digestive enzymes can break down starch into glucose, which we can totally use for energy. Cellulose, on the other hand, is like the tough guy of the group - our enzymes can't really break it down, so it just passes through our system like, "See ya later, alligator!" So, yeah, that's why we can chow down on some fries but not on a salad made of pure cellulose.
Pepsin does not digest. It breaks down proteins into amino acids. Pepsin cannot break down starch. This is probably because the pH of starch is higher than the optimum pH of Pepsin.
2 polysaccharides found in plants are starch and cellulose. :)
