Question 1 - 10
A pigment in a lightabsorbing compound. What
color does any given
pigment appear?
Answer 1 – 10
It appears whatever wavelength (or combination
of wavelengths) that it reflects.
Plants appear green because they reflect the
wavelength of light that is interpreted as
green in our brain.
If I turn off the lights, and make sure no light is
coming into the area, everything appears
black because no light is arriving to your eyes!
Question 1 - 20
At which
location does
the light
reaction
occur and
what is the
structure’s
name?
C.
A.
B.
Answer 1 – 20
The light reaction occurs at location ‘A’ on and
within the thylakoid.
Question 1 - 30
What colors of light typically
power the process of
photosynthesis?
Answer 1 – 30
Red and blue.
Most photosynthetic organisms appear green
which means they are absorbing the energy
from red and blue wavelengths of light and
reflecting the green wavelength of light.
What would happen if you gave a green plant
green light only?
Question 1 - 40
If we take a plant
submerged in
water and apply
white light to it,
what might be
evidence that
the light reaction
is occurring?
Answer 1 – 40
Oxygen bubbles!
The major product of the light reaction is oxygen
(O2). In reality the oxygen escapes in just a
small amount at a time (though at a high rate)
that it rarely forms actual bubbles, but it
would certainly be evidence of the light
reaction occurring!
Question 1 - 50
What are the
two products of
the light
reaction that
are used in the
Calvin cycle?
Answer 1 – 50
NADPH and ATP
NADPH (made from NADP+, 2 e-, and H+ put
together via NADP+ Reductase)
ATP [ADP + P put together via ATP synthase
which is powered by the movement of
protons (H+) from high concentration (in the
thylakoid space) to low concentration (in the
stroma)]
i
Question 2 - 10
What is the
major
product of
the Calvin
cycle?
Answer 2 – 10
A carbohydrate/sugar
(glucose)
Question 2 - 20
At which
location does
the Calvin
cycle occur
and what is
the area’s
name?
C.
A.
B.
Answer 2 – 20
The Calvin cycle occurs at location
‘B,’ the stroma.
Question 2 - 30
What organelle is
responsible for the
two parts of
photosynthesis?
Answer 2 – 30
The chloroplast.
Question 2 - 40
The major reactant
for the Calvin cycle
is carbon dioxide.
From where do
photosynthetic
autotrophs
typically receive
this substance?
Answer 2 – 40
The atmosphere.
Question 2 - 50
Write out the balanced
chemical equation for
photosynthesis.
Answer 2 – 50
Question 3 - 10
What does the word glycolysis
mean?
Answer 3 – 10
The splitting (lysis) of a sugar (glyco).
Question 3 - 20
An organism has no
useable oxygen
after glycolysis and
now must proceed
to what process
that creates a toxic
byproduct?
Answer 3 – 20
Fermentation
Question 3 - 30
Casi and Jill are working hard at
soccer conditioning. Casi
produces 3.07 grams of CO2 over
the course of 2 hours and Jill
produces 3.86 grams of CO2.
Which of the two girls made
more ATP?
Answer 3 – 30
Jill did! The more carbon dioxide that is
produced, the more water and ATP that is also
produced!
Question 3 - 40
Where in the cell does glycolysis
occur and how much ATP is
produced in this step of
cellular respiration?
Answer 3 – 40
Cytoplasm; 2 (net) ATP
Technically glycolysis makes 4 ATP but two of
those four were ATP molecules that we
invested to get the process started…so we end
up with two more than we started with.
Question 3 - 50
You have found a heterotrophic
unicellular eukaryote that is living
in an anaerobic environment.
Describe what you know about
this organism!
Answer 3 – 50
Heterotrophic- feeds on other things
Unicellular- composed of one cell
Eukaryotic- has a true nucleus (not a bacterium)
Anaerobic environment- lives in an environment
that has no oxygen
Question 4 - 10
What reactant is required for
cellular respiration to proceed to
the Krebs cycle?
Answer 4 – 10
Oxygen! If not present, fermentation will occur
instead.
Question 4 - 20
What major product is made
during the Krebs cycle that leaves
the cell?
Answer 4 – 20
Carbon dioxide
Carbon dioxide passively diffuses out of the
mitochondria and cell to the cardiovascular
system (in animals) where it is transported to
the lungs to be released into the atmosphere.
YOU ARE DOING THIS RIGHT NOW. SCIENCE.
Question 4 - 30
Where does the Krebs cycle take
place (be specific) and how
much ATP is produced per
glucose in the
process?
Answer 4 – 30
The inner-membrane space (matrix) is where
the Krebs cycle occurs. It produces 1 ATP per
pyruvate, so 2 ATP per glucose.
Question 4 - 40
What products of the Krebs cycle are
used in the next step of cellular
respiration (electron transport
chain)?
Answer 4 – 40
FADH2, NADH
These carry the electrons necessary to power
the production of ATP in the electron
transport chain.
Question 4 - 50
Write the balanced equation for
cellular respiration.
Answer 4 – 50
The energy is technically also given off as heat.
Question 5 - 10
What is the standard and
maximum amount of ATP
made during aerobic cellular
respiration?
Answer 5 – 10
36-38 ATP
2 from Glycolysis
2 from Krebs
32-34 from Electron transport chain
Question 5 - 20
In what phase of photosynthesis is
an electron transport chain
utilized?
Answer 5 – 20
The light-dependent reaction.
It works very similarly to the ETC found in
cellular respiration.
Question 5 - 30
Where does the ETC occur in the
cell (be specific) and how many
ATP are made?
Answer 5 – 30
The ETC occurs ON the inner membrane. IT
produces 32-34 ATP.
For a ETC to make ATP it has to have a
concentration gradient across a membrane!
Question 5 - 40
Chemiosmosis is the
movement of ions
from high
concentration to low
concentration. In the
mitochondria, what
ion is moving AND
what enzyme is it
powering?
Answer 5 – 40
H+ (protons) are moving from the intermembrane space back into the matrix
(inner-membrane space) which power
ATP synthase.
Question 5 - 50
Generally describe what occurs
during the electron transport
chain’s operation.
Answer 5 – 50
1. Electrons are transported from protein to protein.
2. This movement of electrons powers certain proteins
to actively transport hydrogen (H+) a certain
direction, creating a concentration gradient. (we call
these proteins proton pumps)
3. Protons passively diffuse back to where they were
pumped from through a protein called ATP
Synthase.
4. ATP synthase is powered by the kinetic energy of
the protons and uses such energy to bind ADP and
P together to form ATP.
