Question

Starch is converted into maltose by an enzyme:

• A. maltase
• B. zymase
• C. diastase
• D. invertage

Answer 1

Answer: (C)

diastase

Starch is converted into maltose by an enzyme diastase. During this process, in this regime the diastatic enzymes start acting on the starches, breaking them up into sugars (hence the term saccharification). The amylases are enzymes that work by hydrolyzing the straight chain bonds between the individual glucose molecules that make up the starch chain. A single straight chain starch is called an amylose. A branched starch chain (which can be considered as being built from amylose chains) is called an amylopectin. These starches are polar molecules and have different ends.
