Answer 1

1. Named protein / enzyme sensitive to / affected by change in pH (eg. Hb, carrier proteins in plasma membrane)
2. (Resultant) change of charge / tertiary structure / shape
3. Described effect on named protein or enzyme (eg. less oxygen binds with Hb, less transport across membranes, fewer substrates can fit active site, fewer enzyme-substrate complexes form)
