During glycolysis, two molecules of ATP are produced from each glucose molecule, but the
most ATP is produced during the citric acid cycle.
Oxidation is part of the glycolysis process and ATP is produced, but more ATP is produced
during the citric acid cycle.

c
a. A single circular chromosome
k.
b. A nucleus
an
c. Free-floating nuclear material
d. No organelles
ANS: B

2. A nurse is instructing the staff about cellular functions. Which cellular function is the nurse
describing when an isolated cell absorbs oxygen and uses it to transform nutrients to energy?
w
a. Metabolic absorption
b. Communication
