Give a biological explaination why can humans can degrade starch but not cellulose

Question

Accepted Answer

∻Answer∻ ⚹ Humans can degrade starch but not cellulose due to the presence of amylase enzymes that can break down starch but not the beta-1,4-glycosidic bonds found in cellulose. ⚹ ∻Solution∻ ‖ a ⋮ Enzyme specificity: Humans produce the enzyme amylase, which specifically targets α-1,4-glycosidic bonds found in starch. ‖ ‖ b ⋮ Structural difference: Starch is composed of α-glucose units, which form α-1,4-glycosidic bonds that are easily broken down by amylase. Cellulose, on the other hand, is composed of β-glucose units, which form β-1,4-glycosidic bonds that human enzymes cannot hydrolyze. ‖ ‖ c ⋮ Lack of cellulase: Humans do not produce cellulase, the enzyme required to break down the β-1,4-glycosidic bonds in cellulose. ‖ ∻Key Concept∻ ⚹ Enzyme specificity and substrate structure ⚹ ∻Explanation∻ ⚹ Humans can degrade starch because the structure of starch allows it to be broken down by human enzymes like amylase, whereas the structure of cellulose does not fit the enzyme's active site, and humans do not produce the necessary enzyme, cellulase, to break down cellulose. ⚹◊What enzyme is responsible for degrading starch in humans, and how does it differ from the enzyme that degrades cellulose?⍭ Generate me a similar question◊
