Pls give me idea of a drawing of feedback mechanism in an enzymatic pathway.promise 10 pts for best answer.?

Question

either postive or negative....

i'm sorry for the dsturbnce it just so happen that i'm a 17 yr-old college stdent (1st time to go to school in a foreign country) and one of the brnch of science that im not into is this bio... =) so tnx for your help. im make sure i'll gve credit to the best and clear answers... tnx agen...

Answer 1

ATP synthase. When ATP concentrations are low this amazing machinery kicks up and starts producing ATP. When ATP conc. is high or when ATP needs to be hydrolyzed for heat energy, as in hibernating animals, The enzyme works backwards, breaking down ATP and releasing energy, usually in the form of heat and a H+ gradient.

Answer 2

ATP Synthase is considered to be the universal carrier of chemical energy in the cell. It captures the energy released by the combustion of nutrients and then uses that energy to fuel other reactions that require it. Most ATP is formed in the mitochondria during cellular respiration or in the cytoplasm during photosynthesis. ATP Synthesis was originally isolated from the mitochondria (Walker et al, 1990).
