Difference betwixt Citric acid bicycle in addition to Electron Transport Chain
Cellular Respiration is a catabolic procedure where respiratory substrates similar glucose is broken downward or oxidised to shape carbon dioxide in addition to H2O amongst publish of unloosen energy every bit ATP. This unloosen energy is used to crusade all cellular activities.
Stages of Cellular respiration
1. Glycolysis: glucose broken downward to 2 pyruvate molecules
2. Link reaction: Pyruvate transported to mitochondria in addition to converted to Acetyl CoA amongst the publish of CO2
3.Krebs cycle: Acetyl CoA enters krebs bicycle yesteryear combining amongst oxaloacetate to shape citrate; the laid out chemical compound formed inwards Krebs bicycle (therefore krebs bicycle likewise called every bit citric acid cycle)
4. Electron carry chain in addition to oxidative phosphorylation: NADH in addition to FADH2 produced inwards Krebs bicycle enters electron carry chain, creating a proton motive forcefulness in addition to hold upward produces ATP amongst O2 every bit end electron acceptor forming H2O.
Krebs Cycle vs Electron Transport Chain (ETC)
Krebs Cycle | Electron Transport Chain (ETC) |
Krebs bicycle occurs inwards the mitochondrial matrix | Electron carry chain occurs inwards the mitochondrial inner membrane (cristae) |
Net gain of ATP per glucose molecule is 2 | Net gain of ATP per glucose molecule is 34 (1 NADH=3 ATP & 1 FADH2=2 ATP) |
Reduced NAD in addition to FAD are produced every bit NADH in addition to FADH2 (6 NADH & 2FADH2 per glucose molecule) | NADH in addition to FADH2 are reoxidised to NAD in addition to FAD |
The phosphorylation for ATP synthesis is substrate marking phosphorylation | The phosphorylation for ATP synthesis is oxidative phosphorylation |
CO2 publish or decarboxylation occurs at diverse steps | No decarboxylation |
Chemiosmosis; non involved inwards ATP production | Chemiosmosis (proton slope formation in addition to associated ATP synthesis) involved inwards ATP production |
Aerobic process, but oxygen non straight involved. It needs byproducts from ETC similar NAD in addition to FAD | Aerobic process; oxygen straight involved every bit end electron acceptor |
Carbon dioxide is released every bit a waste product production of these reactions. | Water is released every bit a waste product production of these reactions. |
