OVERVIEW
of CELLULAR RESPIRATION
GLYCOLYSIS
1) What
does the term ÔglycolysisÕ mean? Does
this term accurately describe the process?
2) Where does glycolysis occur inside the
cell?
3) Is
glycolysis aerobic
or anaerobic?
4) How
many ATP are
produced (net gain)?
5)
Glycolysis begins with what substance?
How many carbon atoms are in this substance?
6) What
are the two final products? How many
carbon atoms in each?
7) What
is the function of the reduced coenzymes (carrier molecule)?
KREBS
CYCLE
1) [Fill
in the blanks]: Krebs cycle begins with Acetyl CoA
chemically bonding to _____ to form a new substance called _____. How many carbon atoms in this new
substance?
2) Where does Krebs cycle occur inside the
cell?
3) Is the
Krebs cycle aerobic or anaerobic?
4) What
is the final gain in ATP?
5) Carbon
dioxide (CO2)
is produced during and immediately before the Krebs cycle. How many are produced in each
cycle?
6) What
is the function of the reduced coenzymes (carrier molecule)?
ELECTRON
TRANSPORT SYSTEM (E.T.S.)
1) Where does the ETS occur?
2) Is the
ETS aerobic or
anaerobic?
3) How
many ATP are
produced?
4) Where
do the electrons
come from that are used in this process?
5) What
is the role of oxygen (O2) in the ETS?

Why do
we need to know this stuff?
¥ In your
study of anatomy and physiology you will commonly hear this phrase: Òcarbon
dioxide is a waste product of our cellsÓ. Cellular
respiration shows you where the carbon dioxide is produced. Similarly, you will also commonly hear
the phrase: Òyour body cells
need oxygen to surviveÓ. Cellular respiration
explains the specific role that oxygen plays.
¥
ÒEnergyÓ molecules such as ATP and the concept of ATP hydrolysis come up throughout the
course. The major purpose of
cellular respiration is to produce as much ATP as possible.
¥ If you
want to understand anything about metabolism you must have a solid foundation
in cellular respiration.
