Respiration Notes
1. Overview
There are two forms of Respiration; Aerobic and Anaerobic.
Aerobic Respiration needs Oxygen and produces Carbon Dioxide, Water and ATP. 32
molecules of ATP are produced per Glucose molecule.
Anaerobic Respiration (also known as fermentation) takes place when Oxygen is absent.
In this case Oxygen, Lactate…

Glycolysis is the first stage of both anaerobic and aerobic respiration. It doesn't however
need Oxygen, which makes it an anaerobic process.




Summary
6-Carbon 3-Carbon
Produces NADH Stage 4
Generates 2 net ATP molecules (4 ATP made ­ 2 ATP used = 2 ATP generated)

6. Kreb's Cycle (a.k.a Citric Acid cycle)
The 2C molecule, Acetyl CoA, from the Link Reaction combines with a 4C molecule to
produce a 6C molecule (Citrate, a.k.a. Citric Acid).
This 6C molecule loses CO2 and H+'s to give a 4C molecule and a single molecule of ATP
produced as…

7. Oxidative Phosphorylation
NAD and FAD are coenzymes that carry high energy electrons.
The e- are used in REDOX reactions (reduction and oxidation)
As the NADH and FADH are oxidised (H+ removed) and ATP is made as a result = oxidative
phosphorylation.
Cyanide is a non-reversible inhibitor of enzymes and…
