Redox (Reduction / Oxidation) Reaction: It is a great way of transferring energy.
Reduction: Taking off oxygen, adding an electron, or adding hydrogen.
Oxidation: Adding oxygen, taking off an electron, or taking off hydrogen to
something.
Oxidative phosphorylation - The process of taking something in a phosphate group and
adding it onto another molecule
Substrate level phosphorylation – The process of taking something in a phosphate group out
of a molecule
This is because the human body needs efficiency due to the high powering brain and other
organs.
Cellular Respiration
NAD and FAD are electron carriers (In both respiration and photosynthesis)
Glycolysis

Happens in cytoplasm.
Breaking down sugar.
There are 2 types: aerobic and anaerobic (fermentation)
In the first phase, the investment phase, an ATP is used first. The ATP is broken
down and the phosphate sticks with the 6 carbon of the glucose. A hexokinase is
the enzyme that sticks a phosphate to the 6 carbon of glucose. Next, the glucose
changed into fructose. We get a fructose-6-phosphate. Then an ATP is used again.
The enzyme phosphofructokinase helps in this process.

Citric acid / Krebs cycle
The Krebs cycle happens in the mitochondria; the purpose is to generate energy through the
oxidation of derived from carbohydrates, fats and proteins into carbon dioxide and chemical
energy in the form of ATP.
Electron Transport Chain
The process of pairing up free NAD and FAD with hydrogen atoms to provide energy to
transfer the energy from the Krebs cycle into the chain, which after transported gets
pumped into a proton rotor and reused.
