Answer #1

21. a

Altering the pH of the cytoplasm cannot terminate a cell signalling cascade.

Inside the cell, several enzymes reverse the cellular modifications which are caused by signaling cascades.

b. Phosphatase removes the phosphate (PO4-) group attached to proteins by kinases. This is known as dephosphorylation.

2. cAMP (Cyclic adenosine monophosphate) is degraded into AMP by phosphodiesterase, and

3. Ca2+ pumps present on cell membrane reverses the release of calcium stores.
