When a person chews on a saltine cracker for five minutes, it begins to taste sweet. Which of the following best explains this change in taste?
A
The cracker's starch is converted into amino acids.
B
The cracker is broken down into glucose by amylase in saliva.
C
The cracker absorbs moisture and releases sugar.
D
The cracker's salt content is reduced, enhancing sweetness.
Verified step by step guidance1
Begin by understanding the composition of a saltine cracker, which primarily consists of starch.
Recognize that the enzyme amylase, present in saliva, plays a crucial role in breaking down starch into simpler sugars.
Explain that starch is a polysaccharide, a complex carbohydrate, which amylase breaks down into maltose and eventually glucose, a monosaccharide.
Discuss how the breakdown of starch into glucose results in a sweeter taste, as glucose is a simple sugar with a sweet flavor.
Conclude that the change in taste is due to the enzymatic action of amylase converting starch into glucose, not due to absorption of moisture or reduction of salt content.
