Anabolic processes consume energy to build more
complicated molecules from simpler ones, while
catabolic processes _______ molecules
break down

• Row 1, Col 1

4
What are the 3 components of an ATP molecule?
ATP (Adenosine Triphosphate) is composed of 1)
the sugar ribose, 2) the nitrogenous base
adenine, and 3) a chain of three phosphate
groups

• 1,2

5
How many net ATP molecules are produced during
glycolyis?
2 ATP

• 1,3

6
Photosystem I produces ___ while photosystem II
produces ___?
NADPH ATP

• 1,4

7
Cellular respiration is a (exergonic/endergonic)
because it (releases/consumes) energy.
Exergonic releases

• 2,1

8
The production of which enzyme inhibits ATP (and
citrate) production during cellular respiration?
Phosphofructokinase

• 2,2

9
Name three differences between anaerobic and
aerobic respiration (TIP think about the
products produced and how much energy is made!)
(Student only needs to get three of these!) 1)
Anaerobic is without the presence of oxygen,
while aerobic is with 2) Anaerobic only makes 2
ATP per glucose molecule, aerobic makes between
30-32 3) In anaerobic respiration, the final
electron acceptor is an organic molecule such as
pyruvate. In aerobic respiration, its
oxygen. 4) Anaerobic respiration produces carbon
dioxide, ATP, and either lactic acid or ethyl
alcohol. Aerobic respiration produces carbon
dioxide, water, and ATP 5)Anaerobic respiration
only occurs in the cytoplasm while aerobic occurs
in both the cytoplasm and mitochondria

10
Where do the electrons entering photosystem II
come from?
The splitting of water molecules provides the
source of electrons for photosystem II.

• 2,4

11
Where does a competitive inhibitor bind and what
are the effects? Where does a noncompetitive
inhibitor bind and what are the effects?
Competitive inhibitors bind at the active
site, and they reduce the productivity of enzymes
by blocking substrates from entering active
sites Non competitive inhibitors bind away from
the active site, but change the shape of the
enzyme so the active site functions less
effectively.

• 3,1

12
How many ATPs are made in glycolysis (net),
pyruvate oxidation, Krebs cycle, and the
electron transport chain?
Glycolysis 2 net ATP Pyruvate Oxidation 0
ATP Krebs Cycle 2 ATP total (a cycle for each
pyruvate) Electron Transport Chain 26-28 ATP

• 3,2

13
What is the final electron acceptor in the
electron transport chain and why is this
important?
Oxygen Oxygen captures the electrons (its very
electronegative!) in the very last step of
electron transport, adding a pair of electrons
to an oxygen atom and two hydrogen ions, forming
water

• 3,3

14
Where do light reactions occur in the
chloroplasts? Where does the Calvin Cycle occur?
What are the products of each?
Light reactions occur in the thylakoids and
produce O2 The Calvin Cycle occurs in the stroma
and produces G3P (Glyceraldehyde 3-Phosphate)

• 3,4

15
The binding of an allosteric inhibitor to an
enzyme causes the rate of product formation by
the enzyme to_______. Why?
Decrease In general, any allosteric regulator
functions by changing the structure of the
enzyme to either change the ability of the
active site to bind the substrate or to
facilitate the chemical reaction.

• 4,1

16
ATP, being the product of photosystem __, is used
during the ________ to build one molecule of G3P
from three CO2 molecules
II Calvin Cycle

• 4,2

17
In order for proteins to participate in cellular
respiration, the NH3 (amino group) must be
removed through ________. In order for fats to
participate in cellular respiration, ___________
must take place (the removal of two carbon
molecules at a time). Why do fats produce twice
as much ATP as carbohydrates?
Deamination beta-oxidation because fats are
better electron donors than sugars (they
have more hydrogen atoms, which are far less
electronegative than oxygen atoms. The hydrogen
atoms wont hog the electrons like oxygen
would.

18
Hydrogen ions (H) built up in the thylakoid
compartment after electrons were transferred
through the electron transport chain. The
hydrogen ions then pump through the ______ to
produce ____
ATP synthase ATP

• Which is the most abundant form of energy in a
  cell?
• -Kinetic energy
• -Chemical energy
• Heat
• Mechanical energy
• Electrochemical gradients

Chemical energy

20
The generation of ATP is an ______ process while
the hydrolysis (and release of energy) of ATP is
an ________ process.
Endergonic exergonic

21
Where does the citric acid cycle occur and what
are the products for 1 cycle/1 pyruvate?
In the matrix of mitochondria 1 ATP, 1 FAD2, 2
CO2, 3 NADH

22
The reactions of the Calvin cycle are not
directly dependent on light, but they usually do
not occur at night. Why does this occur??
The Calvin cycle requires products only produced
when the photosystems are illuminated. (The ATP
and NADPH produced during the light reactions
are necessary for the Calvin cycle).
