Cell Respiration
Basic concepts
Glycolisis
Electron Transport Chain and Oxidative phosphorylation
Krebs Cycle
ATP Synthase
Anaerobic Respiration
Aerobic Respiartion
OIL RIG
It is an enzyme which is synthesize ATP by combining ADP and free phosphate group
Electron trasnport system: This is high potential energy from the electron transport chain, will be gradually lowered doen by the releasing of energy

It happends in the same chemical reaction, while one compound looses electrons the other one gains them.
Phosphorylation is the adding of an inorganic phosphate molecule to an organic molecule

When ATP is hydrolyzed, the external phosphate is broken libertating a Pi
NAD, NADH are cofactor in redox reactions
FAD --> FADH2 performs important roles on the last steps of the cell repiration
Coenzyme A (CoA) donate or accept electrons durng the reaction, in this case transfering the acetyl group -COCH3
For each molecule of glucose that is being broken down to 2 pyruvates, two molecules of ATP are formed 2 NADH are also formed can be anaerobic or aerobic
Acetyl Coenzyme A
Each pyruvate oxidizes and combines with Coenzyme A
By products NADH and CO2 are also produced
Acts like a transfering agent in the Krebs Cycle, transfers fatty acids derivates
Takes place at the matrix
Provideas a continuos supply of reduced electron carriers for the electron transport chain
Acetyl CoA combines with a 4-C compound to produce citric acid, a 6-C compound
The citric acid undergoes a decarboxylation reaction which removes carbon dioxide and a series of oxidation reactions which remove hydrogen ions and electrons.
Each glucose molecule produced 2 molecules of pyruvate and so 2 olecules of a Acetyl CoA, the yield per glucose for the Krebs cycle is: 4 CO2, 2 FADH2, 6 NADH, 2 ATP
NADH oxidation, looses 2 electrons
O2 reduction, to form H20
Protein complex in the cristae memmbrane
Energy is generated is used by the complex of proteins to pass protons (H) through the cristae membrane
Is a high concentration of H protons is created in the inter membrane space
