Studied by 2 peopleWhat food gives us
energy
energy is not
recycled
Photosynthesis converts light into
chemical energy
what does cellular respiration break down into energy
glucose
some energy is lost through
heat
waste products of respiration
water and carbon dioxide
All living things perform
respiration
The energy in glucose from glucose is used to make
ATP
Anaerobic
does not require oxygen
aerobic
does require oxygen
the first stage of respiration
glycolysis
Does glycolysis require air
no
Second stage of respiration
krebs cycle
third cycle of respiration
Electron transport chain
glycolysis occurs in the
cytoplasm
How much ATP does glycolysis have a gain of
two
NADH job
electron acceptor; carries electrons to the ETC
why can’t people only do glycolysis
The product is only 2 ATP and not enough to sustain human life
What happens to pyruvic acid
If oxygen is present, it undergoes aerobic respiration. If oxygen is not present, it undergoes fermentation.
How much additional ATP does fermentation produce
None
where does fermentation occur
cytoplasm
two major stages of aerobic respiration
Krebs cycle and electron transport chain
Most of the ATP produced in aerobic respiration was produced by the
electron transport chain
In prokaryotic cells, where does the Krebs cycle and ETC take place
cytoplasm and special structures of the cell membrane
structures of the mitochondria
the outer membrane, inner membrane, matrix, cristae
where is the matrix located
inside the inner membrane
cristae
folds and loops inside the mitochondria; increase surface area for the reaction of respiration
Krebs cycle occurs in what part of the mitochondria
matrix
ETC occurs in what part of the mitochondria
cristae membrane
bridge reaction
the bridge between cytoplasm and mitochondria, anaerobic and aerobic respiration, and glycolysis and Krebs cycle
NAD and FAD
electron carriers in the Krebs cycle
one turn of the Krebs cycle produces
2 CO2; 1 ATP; 3 NADH; 1 FADH2
Electron transport chain is
a series of four protein complexes, creating ATP in a complete system named oxidative phosphorylation.
the majority of the energy contained in glucose is given off as
heat
two types of fermentation
alcoholic and lactic acid
How did oxygen enter the atmosphere
Photosynthetic organisms
