cellular respiration Flashcards
cellular respiration is…
oxidative, exergonic
glycolysis NET
2ATP added. 2NADH made. 4 ATP Made 2 pyruvate
glycolysis key notes
ATP make via substrate level
- hexokinase phosphorlyzes glucose so it can’t diffuse out
PFK adds 2nd phosphate and makes it PERMANENT GLYC. major reg step
major reg step in glycolysis
PFK adding 2n’s phosphate
pyruvate decarb
in the matrix now. make 2 NADH and 1 CO2 via PDC
Krebs cycle process
acetyl coA merges with oxaloacetate then citrate
Krebs cycle net
3 Nadh , 1 FADh2, 1 ATP (sub phos) and 2 co2 per TURN
- co2 is exhaled
ETC
oxidative phos
- NADH drops at complex 1
- farad drops at complex 2
- pump H’s
- split water for oxygen final e acceptor to make water
- pump back H+ and make ATP
energy total
36 ATP but 38 in prokarya
chemiosmosis
proton gradient.
highest proton concnetration
inter membrane space!
anaerobic respiration
cytosol. includes glycolysis and fermentation.
alcohol fermentation
occurs in plants, fungi and bacteria
- pyruvate turns to acetaldehyde and co2 then then accepts e to become ethanol
- thus generates NAD+
lactic acid fermentation
pyruvate turns to lactate and then is converted back to glucose.
gluconeogenesis
making glucose in liver and kidney
