Answer:
The molecules that are used to digest
the starch are identi ed as enzymes, ,
biological catalysts, amylase molecules,
etc.; The molecules produced when
starch is digested are identi ed as
glucose molecules, simple sugars,
monosaccharides, sugars, etc.; Why starch
must be digested before its building block
molecules can enter the bloodstream is
explained as—Starch molecules are too
large, they are too big to get from the
digestive tract into the blood, large
molecules cannot di use through cell
membranes, etc.; the structure in the cell
that will produce ATP from the starch
building blocks is the mitochondrion
(mitochondria); Why ATP is important to
cells is stated as—ATP is the molecule
that supplies usable energy for all the
activities of a cell, ATP molecules
provide energy for cells.
