__”Photo”__ part of “photosynthesis” (means light)
_”Synthesis” part of “photosynthesis” (means to make
something)
Location: __thylakoid membrane_______
Location: __stroma__________
Overview:
Light energy hits chlorophyll and adds energy to
electrons, which are stored as ATP.
Overview:
Carbon dioxide (CO2) is taken in and changed into
sugar.
H2O molecules are broken apart and O2 is released.
H+ travels on NADP+ to the dark reactions.

respiration process:
What comes out of the
cellular respiration
process:
Using the charts you filled in above, explain why
cellular respiration considered to be the “opposite” of
photosynthesis.
Cellular respiration occurs in the __________________
of the cell.
Cellular respiration always begins with what process?
In this process, ___________________ is broken down
into ______________ acid, hydrogen ions, and electrons.

4 molecules of ATP were produced; however, _____
were needed to start glycolysis. Therefore, the net
production of ATP from glycolysis is ________ ATP.
If oxygen is present after glycolysis,
____________________ respiration will take place. The
first step of this process is the __________
___________ cycle or __________ cycle.
This cycle is followed by the ____________
_____________ _____________, which creates ______
ATP molecules.
What is the total output of ATP including both glycolysis
and the ETC?
If oxygen is not available, the cell will use
_______________ ________________ after glycolysis.
This is also known as ______________.

Step 1: Glycolysis breaks 1 glucose molecule into 2 pyruvic acid molecules
and has a net output of 2 ATP.
Step 2: Pyruvic Acid releases a CO2 and forms Acetyl-CoA. (This happens
with each Pyruvic Acid.)
Step 3: Acetyl-CoA enters the Citric Acid Cycle, which releases CO2 and
makes 1 ATP. (This happens with each Acetyl-CoA.)
Step 4: High energy electrons pass from the Citric Acid Cycle to the
Electron Transport Chain using NADH and FADH2. These are used to
produce more ATP. O2 is the final electron acceptor, which produces H2O.
At the end of the Aerobic Respiration Process, 36 ATP have been
created from 1 molecule of glucose.
