ATP and GTP..what's the difference?

Postby victor » Thu Jun 16, 2005 1:55 pm

Since all of you agree that BioChem is put inside the molecular bio I wanna ask something. What are the differences between ATP (Adhenosine triphospate) and GTP (Guanosine triphosphate)? is there any different function of these two?

ATP can be produced thru different processes:
- in mitochondria thru oxidative phosphorylation
- (in plants) iin chloroplasts thru photosynthesis

GTP is produced in the Krebs Cycle but the molecule can be easily converted to ATP by the action of the Nucleoside Diphosphokinase.

ATP is responsible for providing energy to carry out many of the body's functions. It's reponsible for regulating biochemical pathways. We also feel pain when ATP is released from a damaged cell.

GTP is used as an energy source in protein synthesis. It's also responsible for enegy transfer within the cell.

hope this helps...

I know that GTP is formed between the process from sucnnymil CoA to Sucsinic acid. So, GTP is responsible in protein synthesis...um, how anout like this..if the synsthesis of proteins are enough, would the excess of GTP converted into ATP?
