Cellular respiration Flashcards
cellular respiration
biochemical process that metabolises glucose to release usable energy in the form of ATP
aerobic respiration conditions
presence of oxygen
aerobic respiration location
cytosol and mitochondrion
anaerobic respiration location
cytosol
anaerobic respiration conditions
no oxygen present
primary source of energy
glucose, in all organisms except Archaea
glycolosis reactant
glucose
glycolosis products
two pyruvate
glycolosis energy production
two NADH
glycolosis ATP in

two
site of aerobic respiration
mitochondrion
ATP full name
adenosine triphosphate
cristae
inner membrane folds
crista
inner membrane fold
mitochondrion matrix
viscous space within the inner menerane
citric acid cycle alternative name
Kreb’s cycle
citric acid cycle reactants
pyruvate and oxygen
citric acid cycle products
two carbon dioxide
citric acid cycle energy production
three NADH one FADH2
alcohol fermentation users
plants and micro-organisms including yeast and some bacteria
electron transport chain location
matrix of mitochondrion
glycolosis ATP production per glucose molecule
net two
citric acid cycle ATP production per glucose molecule
two
NADH and FADH2 role in electron transport chain
transports electrons with stored energy, creating a chemical gradient across the inner mitochondrial membrane
electron transport chain alternative name
oxidative phosphorilation
alcohol fermentation reactant
pyruvate
alcohol fermentation ATP production per glucose molecule
two
alcohol fermentation products
ethanol and carbon dioxide
electron transport chain reactants
hydrogen ions and oxygen
electron transport chain product
hydrogen
electron transport chain ATP production per glucose molecule
28 - 34
types of anaerobic respiration
alcohol fermentation and lactic acid fermentation
lactic acid fermentation users
animals
lactic acid fermentation reactant
pyruvate
lactic acid fermentation ATP production per glucose molecule
two
lactic acid fermentation product
lactic acid
lactic acid fermentation conditions
initially during strenuous exercise
reversibility of fermentation
lactic acid can revert to pyruvate
advantage of aerobic respiration
more ATP is produced
advantage of anaerobic respiration
faster production of ATP
factors that affect the rate of respiration
temperature, level of glucose and level of oxygen
compensation point
when the uptake of carbon dioxide for photosynthesis is equal to the volume of carbon dioxide produced by respiration
