A histidine residue in the active site of aspartate transcarbamoylase, or ATCase, is thought to be important in stabilizing the transition state of the bound substrates. Predict the pH dependence of the catalytic rate, assuming that this interaction is essential and dominates the pH ‑activity profile of the enzyme.

Particle model to predict what will happen if a sharp object creates a hole in the soccer ball

Melting and boiling are endothermic processes. this means that these processes absorb energy from their surroundings in order to occur. use this information and the data you collected in the phase change gizmo to describe what happens to the temperature of water when you boil it, then explain why this result occurs.
