Phosphorylation - phosphate group added to molecule (protein). Kinase - accelerate the addition of phosphate group to a molecule. Phosphatases - remove phosphate group to molecule. Endergonic chemical reaction ATP forms intermediate complex with substrate and enzyme reaction. Intermediate Complex - allow 3rd phosphate with its energy to transfer to substrate - break apart then the energy is used to modify substrate and convert it into product of reaction. ADP molecule and free phosphate ion release into medium undergo recycling called CELL METABOLISM. Substrate level in phosphorylation - Metabolism reaction result in production of ATP or GTP with energy from higher bond leads to phosphorylation of ADP or GDP. Mechanism of ATP formation involves the transfer of phosphate from a donor molecule ADP. Energy released during hydrolytic release of Pi must be high enough to attach Pi to ADP. Oxidative phosphorylation - Electrons from food molecule is transferred to molecular energy, uses chemiosmosis, happens in mitochondria of eukaryotic cell or plasma membrane of prokaryotic cell. Chemiosmosis - production of ATP in cellular metabolism, generate 90% of ATP during glucose catabolism.
Understand the Problem
The question appears to be providing a summary or explanation of various biochemical processes like phosphorylation, kinase and phosphatases functions, ATP formation, and the details of oxidative phosphorylation and chemiosmosis. It outlines key concepts related to cellular metabolism and energy transfer.
Answer
Phosphorylation is the addition of a phosphate group to a molecule, aided by kinases, while phosphatases remove them. ATP plays a key role.
Phosphorylation involves the addition of a phosphate group to a molecule, typically facilitated by enzymes called kinases, while phosphatases remove these groups. ATP is a key player providing the phosphate group in these reactions. It is crucial in cell metabolism and energy transfer processes.

More Information
Phosphorylation is a vital cellular process affecting numerous signaling pathways, protein functions, and regulates metabolic pathways. It's a reversible mechanism involving kinases and phosphatases that modify protein function and activity.
Tips
A common mistake is confusing phosphorylation with oxidative phosphorylation, which specifically refers to ATP production in mitochondria.
