At the subcellular level, starch is stored in amyloplasts in
the endosperm of cereals. Two enzymes responsible for initiating starch
degradation are α- and β-amylase
a) α-Amylase hydrolyzes starch chains internally to produce
oligosaccharides consisting of α(1,4)-linked glucose residues
b) β-Amylase degrades these oligosaccharides from the ends to
produce maltose, a disaccharide
c) α-Amylase degrades these oligosaccharides from the ends to
produce maltose, a disaccharide
d) α-Amylase
hydrolyzes starch chains internally to produce oligosaccharides consisting
of β(1,4)-linked glucose residues
e) β-Amylase also converts maltose to glucose
Which of the following combination from the above statements is correct?
