What molecule is oxidized to
donate electrons for
photosynthesis?
H20 is oxidized and donates it’s
electrons to the reaction centre of
photosystem II
What are the products of the light
reaction in photosynthesis?
ATP and NADPH
1 turn of the Clavin Cycle
generates this 3 carbon molecule:
PGAL (Phosphoglyceraldehyde)
which when combined with
another PGAL forms Glucose
Which molecule gets reduced in
the light dependent reactions of
photosynthesis?
NADP is reduced as it gains
electrons and hydrogen to form
NADPH
In photosynthesis, a
chemiosmotic gradient of this
molecule allows ATP synthase to
produce ATP.
A hydrogen gradient is created
across the thylakoid membrane a
this differential gives ATP
synthase enough energy to
produce an ATP.
This phase of cellular respiration
does not require oxygen
Glycolysis does not require O2
and initiates aerobic as well as
anaerobic respiration.
What is the net production of
ATP from Glycolysis?
2 ATP are produced in
glycolysis.
Name the two coenzymes that
transport hydrogen in
mitochondria.
NAD and FAD are the
coenzymes that transport
hydrogen.
What is the net production of
ATP from lactic acid
fermentation?
The only 2 ATP are from
glycolysis
How many NADH molecules are
produced in ethanol
fermentation?
None – the two that are produced
in glycolysis are used when
converting pyruvate to ethanol
How many ATP (net) are
produced in aerobic cellular
respiration
36 Total ATP
Each NADH contains enough
energy to produce _____ ATP’s
3 ATP’s per NADH
2 ATP’s per FADH
The Kreb’s cycle produces CO2.
Where else in cellular respiration
is CO2 emitted?
2 CO2 molecules are lost in
between Glycolysis and the
Kreb’s cycle (in the production
of Acetyl-CoA)
What is the net production of
ATP from ethanol fermentation?
2 ATP molecules are produced in
the Glycolysis phase of anaerobic
respiration
Which NADP generate more
energy for the cell, those
produced in the cytoplasm or
those produced in the
mitochondria?
Those produced in the
mitochondria generate more
energy as they don’t need to be
transported into the mitochondria
What do enzymes do?
Catalyze / speed up reactions
Co-enzymes are similar to
enzymes. Name one that is
important for photosynthesis.
NADP is a coenzyme used in
photosynthesis
What is the name of the enzyme
that breaks eliminates H2O2 from
our tissues?
Catalase
Name 3 conditions that affect the
speed of a reaction
Temperature, pH, Surface Area,
Amount of enzyme, Amount of
substrate / product
The name of the enzme
responsible for fixing CO2 from
the atmosphere in the Calvin
Cycle.
Rubisco
What is the first law of
thermodynamics?
What is the second law of
thermodynamics?
What does it mean to be
“oxidized”?
What is the name for the reaction
when light energy splits a water
molecule?
How many fish are there in the
MCHS fishtank?
