Which of the following phosphorylation occurs in power house of eukaryotic cell?
Options
- AOxidative phosphorylation
- BSubstrate level phosphorylation
- CPhotophosphorylation
- DBoth (a) and (b)
Correct answer
D. Both (a) and (b)
Step-by-step solution
The powerhouse of the eukaryotic cell is mitochondria. The formation of ATP directly in the metabolic reaction is called substrate-level phosphorylation or transphosphorylation. It occurs when succinyl CoA is converted to succinic acid in Kreb's cycle, thus producing 1 ATP. The energy of oxidation and reduction is utilized form formation of ATP during an electron transport system this is called oxidative phosphorylation. Maximum ATP is generated through oxidative phosphorylation.
