At the beginning, your contractions may be very irregular. One contraction may be 15 minutes apart from the next or as close as 5 minutes. The length of the contraction is probably 30 seconds to one minute in length. As the first stage of labor progresses, your contractions get closer and more regular.
ATP-binding motif. An ATP, adenosine triphosphate, binding motif is a 250 residue sequence within an ATP binding proteinâs primary structure. The binding motif is associated with a proteinâs structure and/or function.[1] ATP is a molecule of energy, and can be a coenzyme, involved in a number of biological reactions. ATP is proficient at interacting with other molecules through a binding site. The ATP binding site is the environment in which ATP catalytically actives the enzyme and, as a result, is hydrolyzed to ADP. The binding of ATP causes a conformational change to the enzyme it is interacting with.
Making the world better, one answer at a time. Because the membrane bound ATP Synthase protein uses high energy to bond adenosine diphosphate (ADP) and phosphate (P) into adenosine triphosphate (ATP) and this requires a lot of energy because it is very difficult to bond another P to ADP (Already has two).
