Rather than forming a salt and water from an A-B reaction, a salt and water react to form an acid and a base.. You MUST determine if you have a Strong or Weak Acid and a Strong or Weak Base.. ATP. ATP powers cellular work by coupling exergonic and endergonic reactions. ATP Drives:. Mechanical work like the beating of cilia, muscle contraction, cytoplasmic flow, chromosomal movement. Transport work like pumping substances across membranes. Active Transport Driven by ATP Hydrolysis. The net flow of molecules by facilitated diffusion, through either carrier proteins or channel proteins, is always energetically downhill in the direction determined by electrochemical gradients across the membrane. . . . Here we make use of an integrated approach using high-magnetic-field solid-state NMR, X-ray crystallography, and first-principles computation that enables the investigation of enzyme catalysis at a fine level of chemical detail. The X-ray crystal structure provides a coarse framework upon which models of the active site are built using first-principles computational chemistry and various active site chemistries are explored. .
