respiration Flashcards
(28 cards)
external respiration
the process of exchanging gases with the enviroment
internal respiration
controlled release of energy from food using enzymes
aerobic respiration
the release of energy from food in the presence of oxygen
aerobes
things that respire using oxygen
chemical equation- resp
C6H12O6+ 6O2= 6CO2 + 6H2O+ Energy
glycolysis
the breaking down of glucose- 6 carbon carb into 3 carbon molrcule pyruvic acid- anaerobic process
glycolysis location
cytosol
prekrebs cycle location
mitochondrian
2b krebs cycle
matrix or lumen
electron transport system
cristae of mitochondria- infoldings increase surface area for ets
why is the production of ATP in ETS called oxidative phosphorylation?
addition of a phosphate in the presence of oxygen
why is cyanide fatal to aerobes
prevents protiens from recieving and passing on electrons- no ATP can be formed
anaerobic respiration
release of energy from food in the absence of oxygen
what is pyruvic acid converted to in anaerobic respiration
lactic acid / ethanol and CO2
anaerobic respiration location
cytosol
lactic acid word eq
glucose- 2lactic acid & small amount of energy
Alcohol fermentation
glucose- 2 ethanol + 2 CO2+ small amount of energy
biotechnology
the use of living things to carry out useful reactions
bioreactor necessary conditions
correct nutrient supply, temperature, pH
MICRO ORGANISM IN BIOPROCESSING
bacteria; beer, wine yogurt
yeast; baking
fungi; antibiotics
micro organism immobilisation
same methods; cells not damaged, reusable
light stage location
grana
dark stage
stroma
pathway 1
cyclic photophosphorylation- ADP + P= phosphorylation, energised by light, travel in cycle- cyclic photophorylation
