Respiration : - Coggle Diagram
Respiration :
Anaerobic respiration
Oxidation of glucose - incomplete
No final Electron acceptor aka OXYGEN
Stages
Glycolysis
Fermentation
2 ATP Produced
Location - cytoplasm
Anaerobic Pathways
Ethanol fermentation
Pyruvate is decarboxylated to ethanal - CO2 produced
2 Hydrogen from reduced NAD is transferred to Ethanal
3 Ethanal is reduced to ethanol
Enzyme - alcochol dehydrogenase
Lactate fermentation
Hydrogen from reduced NAD is transferred to Puryvate
Pyruvate is reduced to lactate
Enzyme - lactate dehydrogenase
Aerobic Respiration
Glycolysis
Location - cytoplasm
Stages
Phosphorylation - trapping the glucose
Lysis - splitting the glucose molecule in two
Oxidation
Dephosphorylation
Pyruvate is produced
Result in production
2 Pyruvate (3C) molecules
Net gain 2 ATP
2 Reduced NAD
Link Reaction
Enter the mitochondrial matrix
when O2 is available
via active transport
Steps
Dehydrogenation
Decarboxylation
Production of Acetyl Group
Combination with CoA and Acetyl Group
Acetyl CoA is formed
Result in production
Acetyl CoA
CO2
NADH
Kreb's Cycle
Series of enzyme controlled reactions
Oxaloacetate is regenerated
Decarboxylation of citrate
Releasing 2CO2 as waste gas
Dehydrogenation of citrate
Reduction of NAD and FAD
Substrate-level phosphorylation
ATP formation
Location - matrix
Oxydative Phosphrylation
Location - inner membrane
Steps
H is donated by NADH and FADH
H atoms split into protons and electrons
Electrons move through ETC
Energy release
Protons are transported into intermembrane space
Concentration gradient is established
Protons return to the matrix
ATP synthesis
O2 combines with protons and electrons - H2O is formed
