oxidative phosphorilation Flashcards
what is oxidative phosphorilation made up of
electron transport chain
chemosmosis
how is an electrochemical gradient formed
during electron transfer chain electrons are passed from one molecule to another and energy is released in electron transfer forming a electrochemical gradient
how does oxidative phosphorilation make atp
in chemiosmposis the energy stored in the gradient is used to make ATP
what is the final accepter at the end of the electron transfer chain
oxygen which combines with protons to form water
what performs oxidative phosphorilation and what does this produce
electron transfer chain
large amounts of ATP
what does the changing of energy do
drives chemiosmosis
what does the drive of chemiosmosis do
move protons across the membrane
give two reasons why oxidative phosphorilation is not 100% effective
protons leak across membrane
atp is used moving pyruvate into the mitochondria by active transport
if there is not enough glucose for respiration what else is used
lipids
protiens
describe respiration of lipids
lipids hydrolised into glycerol and fatty acids
glycerol phosphorlated and converted to TP which enters glycolosis
fatty acids broken down into 2 fragments which are converted to Acetyl COA which enters the krebs cycle
describe respiration of protiens
hydrolysed to amino acids deaminated to remove amino group
enter different pathways according to the number of carbons
3c converted to pyruvate
5c converted to krebs cycle
in respiration of proteins what is 3c converted to
pyruvate
in respiration of proteins what is 5c converted to
krebs cycle
what is deamination
removing amino acids
where does oxidative phosphorylation occur
in the mitochondria
