Question

an incomplete equation for the digestion of starch using saliva is shown as saliva + starch(in a test tube)----> what will be the likely outcome of this a)saliva will convert starch into complex fat molecules b)saliva will convert starch into complex sugar molecules c)saliva will brake down starch into simple sugar molecules d)saliva will brake down starch into simple protein molecules​

Answer 1

Answer:

c

Explanation:

Answer 2

C) Saliva will break down starch into simple sugar molecules.

Amylase, an enzyme found in saliva, breaks down starch into simple sugars, which are then further broken down by enzymes in the stomach and small intestine.

Breakdown of Starch:

• Salivary amylase in the mouth begins to break down starch, and pancreatic amylase continues the process in the intestines.
• As the stomach's pH is inappropriate for amylase action (optimal pH 7), starch digestion by amylase does not occur there.
• Amylase breaks down amylopectin into branched chains known as dextrins and breaks down amylose into maltose subunits (disaccharide).
• Maltase enzymes, which are affixed to the epithelial lining of the small intestine, digest both maltose and dextrin.
• Glucose monomers are produced as a result of the hydrolysis of maltose and dextrin.
• Glucose can either be stored in animals as the polysaccharide glycogen or hydrolyzed to create ATP (for cell respiration).
• Other disaccharides can be broken down to produce glucose monomers as well (such as lactose and sucrose)
