the more reduced a molecule is, themore
potential energy thats in the molecuel
the e- removed during oxidation must be transferred to an e- acceptor which becomes
name three e- acceptors
1) aerobic respiration
2) inorganic compounds other than O2, like nitrate, sulfate, carbon dioxide
3)organic compounds
oxidation of organic molecules, you can't fermentate inorganic stuff
♫ uses organic molecules as e- acceptor
fermentation never yields as much energy as ...
aerobic respiration of the same molecule
fermentation occurs in the absence of
free O2
in fermentation, the organic compound being oxidized is never ______
completely oxidized u only partially break it down
in fermentation the organic compound being oxidized (being used as an energy source)is split into fragments
1) the first is oxidized
2) the second accepts the e- and beomces reduced
the most commonly usd pathway of fermentation
glycolysis produces
2 atps
2 pyruvates per glucose
energy is conserved as ATP in a process called
substrate level phosphoylation
u add a P to ADP to make ATP
YOu cannot ferment f---
fatty acids are just C2 in a long chain and you cannot fit anymore H's.
Many compounds other than glucose can be fermented. Compound must be sufficiently _______ so that it has a portion of the molecules that can accpet e- be reduced
in aerobic respiration of organic copmpounds,e- are accepted
by O2
in aerobic respiration of organic copmpounds, e- are transferred to O2 by the
electron transport system
in aerobic respiration of organic copmpounds,ETS
uses the e- as asource of energy to produce ATP
if you ferment glucose you get____ ATPS
if you respire glucose you get ____ ATPs
36-38, depending on the specie
by using ETS the substrate which is glucose can be COMPLETELY
oxidized to CO2 and H2O
Oxidative Phosphorylation
atp synthesis during respiration
compounds which cannot be fermented can be
in procaryotes, ETS is associated with a
cell membrane
in eucaryotes, ets is associated with
Glucose ► 2 pyruvates ►kreb's cycle ►ETS ►most ATP's
require O2
protein ► amino acids►ETS ►most ATPs
require O2
lipids ► fatty acids ►ETS ►most ATPs
require O2
in ANAEROBIC respiration of Organic compounds, the oxidation of an organic energy source will be
an e- acceptor other than OXYGEN but still inorganic
Inorganic compounds most often used are
♪nitrate which becomes ammonia if it accepts enuff Hydrogens
♪sulfate, which if accepts enuff H's becomes hydrogen sulfide
in ANAEROBIC respiration of Organic compounds, the most COMMONLY used e- acceptor is__
in ANAEROBIC respiration of Organic compounds an ETS system is__
the only organisms capable of anaerobic respiration are
certain bacteria
oxidation of inorganic compounds include
oxidation of inorganic compounds is similar to respiration except
inorganic molecules are oxidized
in oxidation of inorganic compounds ETS is involved in ATP formation and ___ is usually the e- acceptor
use inorganic molecules as e- source
use organic molecules as e- source
organisms that eat H2 oxidize it to
in energy production by photosynthesis, light energy excites _______ which emit electrons
pigment molecules (chlorophyll, bacteriochlorophyll)
in light dependent reactions, electrons are
carried by the ETS used in ATP formation
oxidative phosphorylation occurs in what types of reactions?
light dependent reactions of photosynthesis
dark reactions are
light independent reactions of photosynthesis
dark reactions are an example of
light independent reactions of photosynthesis are also called
carbon fixation
in carbon fixation, the ATP from the light rxn is used as a source of energy to _____
combine CO2 & water ► glucose
Oxygenic photosynthesis produces
Oxygenic photosynthesis produces O2
ex. plants, algae, bacteria
ANoxygenic photosynthesis produces
ex. phototrophic bacteria
USAGE of ernergy produced by Catabolism or photosynthesis include
1) Heat production
3) movement
4)active transport pumps***to mantain homeostasis ex. Na+ K Ca++ pumps
Biosynthetic metabolism =
biosynthetic metabolism requires
ATP energy
all living cells require the cynthesis of 4 molecules which are
CLP'N (think clippin!)
carbohydrates, lipids , proteins, nucleic acids
monosaccharide make
fatty acids make
amino acids make
nucletotides make
nucleic acids
