ATP & Cellular Respiration


Cellular Respiration ­ the process of deriving energy from glucose (in the form of ATP).
Before energy can be utilised by our cells it must be turned into ATP (Adenosine Triphosphate) ­ a
specific shortterm energy storage…

Bring together iP + ADP to form ATP ( ATP synthase ­ an enzyme)
Transport electrons and protons in the form of Hydrogen ( NAD & NADH , and FAD & FADH2 ­
coenzymes and reduced coenzymes )
Coenzymes are molecules…

Krebs Cycle
This is an AEROBIC REACTION: can only occur when oxygen is present.
Occurs across the innermembrane of the mitochondria.

Acetyl CoA (2C ) combines with Oxaloacetate (4C Compound). Citric Acid (or Citrate ) is formed (a
6C Compound ).…

pumped. Therefore, less protons are pumped across the membrane per FADH2 , meaning less
ATP is formed as a result.

During Oxidative Phosphorylation therefore, 34 ATP molecules are produced. Therefore, from one
glucose molecule, 38 ATP are produced altogether (4 ATP…
