Phosphorylation

Definition

noun, plural: phosphorylations

The transferring of phosphoryl group from a donor to the recipient molecule


Supplement

Phosphorylation is important in living cells since it is through this that energy-rich molecules (e.g. ATPs) are formed. For instance, a phosphoryl group (phosphate) is added to ADP, thus forming ATP, usually catalysed by phosphorylases and kinases.

Re: Types of phosphorylation ?

Substrate level phosphorylation takes place inside the mitochondria during glycolosis and the Krebs cycle. Oxidative phosphorylation takes place in the membranes of the mitochondria during the electron transport chain. Photo phosphorylation ...

Protein synthesis during S phase

... is active during replication. I was guessing the inactivation of all other protein synthesis had something to do with CDK/cyclin levels, some phosphorylation, or something to do with steric impedement at the origin of replication. Still, that doesn't explain the histone part...

Fail to see under physiological stimulation

... of growth factor that is known to activate endogenous Src. I had tried looking at both GFP-tagged exogenous or endogenous but all fail to see the phosphorylation of my protein evoked by PDGF.

Re: NADH and FADH2

i m gonna answer victor's question.. actually each NADH produced in glycolysis....produces 2 instead of 3ATPs...and it is called substrate level phosphorylation...because oxygen is not involved in it....hence the 2NADHs produced in glycolysis produces 4 ATPs...and i think total ATPs produced in ...
