Cellular Respiration Take 2 Flashcards
Goal of cellular respiration?
to make ATP
steps in order
- glycolysis
- Intermediate step (pyruvate transported to mitochondria
- Citric Acid Cycle
- Oxidative Phosphorylation
what two processes make up oxidative phosphorylation?
ETC and chemiosmosis
Glycolysis inputs/ outputs
in: glucose, NAD+, and ADP
out: NADH, pyruvate, ATP
intermediate step (Acetyl CoA formation) inputs/outputs
in: pyruvate, NAD+, coenzyme A
out: NADH, acetyl CoA, CO2
Citric Acid Cycle inputs/outputs
in: Acetyl CoA, NAD+, ADP
out: ATP, NADH, CO2, coenzyme A
Oxidative phosphorylation inputs/outputs
in: NADH, ADP, O2
out: NAD+, ATP, water
glycolysis takes place in…
cytosol
Acetyl CoA formation takes place in…
mitochondrial matrix
Citric Acid Cycle takes place in…
mitochondrial matrix
Oxidative Phosphorylation takes place in…
inner mitochondrial membrane
What do FADH and NADH do
coenzymes which have the ability to transfer electrons and assist in doing so to make more ATP
glucose is broken down into…
2 pyruvate (3 carbon)
pyruvate is oxidized into…
acetyl (2 carbon) with a coenzyme A attached (now ready to enter citric acid cycle!)
substrate level phosphorylation
ATP production via direct enzymatic phosphorylation (accounts for very little ATP production)
Oxidative Phosphorylation
couple the electron transport chain with the “downhill” H+ movement to produce ATP (90% of ATP production)
Aerobic
O2 present
Anaerobic
O2 NOT present
Cellular respiration
O2 PRESENT
waste products: H2O and CO2
32 ATP produced per glucose
Fermentation
NO O2 present
Waste products: lactic acid, ethanol, CO2
phosphorylation
adding a phosphate group
oxidize
take electrons and hydrogen away
oxidation-reduction reaction
chemical reaction where electrons between two species are transfered
reduction
reactants gain electrons
hydrolyzed
to split with water
reducing agent
looses electrons and is oxidized
oxidizing agent
gains electrons an becomes reduced
Redox reaction
where both oxidation and reduction take place
