1. Where does most of the CO2
that we breathe out come from?
1. Sugar broken down
in Glycolysis.
2. Carbon compounds
broken down in the
Krebs cycle.
3. Fermentation of
pyruvate into lactic
acid.
2. We breathe in oxygen. What
do we use it for?
1. To pick up carbon
atoms from the Kreb’s
cycle.
2. To clean out stale
products from our
cells.
3. To pick up electrons
and hydrogen ions at
the end of the electron
transport chain.
3. We also saw the electron transport chain
in photosynthesis. What did it produce?
1.
2.
3.
4.
Glucose
G3P
ATP
Citric Acid
4. So yes, ATP is produced in the
chloroplast. Where is it used and what for?
1. In the chloroplast,
as an energy
source for
assembling carbon
compounds.
2. In the plant cell, to
run the cell’s
metabolism.
3. Anywhere the cell
needs it.
5. If the chloroplast keeps all of its ATP for its
own use, how does the rest of the plant cell get
ATP?
1. From the sun.
2. From cellular
respiration by the
mitochondria.
3. From the C4 cycle.
4. From the lightindependent
reactions of
photosynthesis.
