Metabolic Sources of ATP
(or GTP) In the Body

There are Two Types of Phosphorylation reactions that
produce ATP (or GTP) in our body:

1. Oxidative-phosphorylation (in the respiratory chain of
mitochondria).

2. Phosphorylation at substrate level (non-oxidative
phosphorylation), e.g. Glycolysis (in cytosol), Citric acid
cycle (in mitosol or matrix of mitochondria)
