1. ATP acts as a carrier of chemical energy within cells, undergoing phosphorylation and hydrolysis reactions.
2. During hydrolysis, ATP is broken down into ADP + Pi, releasing energy that powers cellular work like transport, mechanical work, and chemical reactions.
3. ATP can be regenerated through phosphorylation reactions coupled to exergonic processes like cellular respiration, using the energy released to drive the endergonic phosphorylation of ADP back to ATP.
This shuttling of energy from exergonic to endergonic reactions via ATP hydrolysis and regeneration is essential for powering metabolism.

Biological oxidation (part - III) Oxidative Phosphorylation
- Mechanism of Oxidative Phosphorylation
-- Chemiosmotic theory
-P:O Ratio
Substrate Level Phosphorylation
Shuttle Systems for Oxidation of Extramitochondrial NADH
ATP synthase—also called FoF1 ATPase is the universal protein that terminates oxidative phosphorylation by synthesizing ATP from ADP and phosphate.
ATP Synthase is one of the most important enzymes found in the mitochondria of cells
An enzyme is a substance that acts as a catalyst in living organisms, regulating the rate at which chemical reactions proceed without itself being altered in the process. The biological processes that occur within all living organisms are chemical reactions, and most are regulated by enzymes
This presentation was prepared in order to take Lecture of students in a summarised way and to provide them with the short, sweet and concise notes. It is based on PCI syllabus and is meant for B. Pharm. Second Semester...
