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".

No, starch is easier to digest.


Why can humans digest starch but not cellulose?

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.

Why can you digest bread but not paper?

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"


Which is dieWhis of these is dietary fiber Glycogen Sucrose Cellulose Starch?

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.

No. Cellulose and starch are both forms of carbohydrates, not a form of one another.


Starch and cellulose are polysaccharides but you can eat or digest starch and not the cellulose why?

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.


Can you digest starch?

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.
