support: What is the function of a phosphatase? a. A phosphatase removes phosphorylated amino acids from proteins. A phosphatase removes the phosphate group from phosphorylated amino acid residues in a protein. A phosphatase phosphorylates serine, threonine, and tyrosine residues. A phosphatase degrades second messengers in the cell. How does NF-κB induce gene expression? a. A small, hydrophobic ligand binds to NF-κB, activating it. Phosphorylation of the inhibitor Iκ-B dissociates the complex between it and NF-κB, and allows NF-κB to enter the nucleus and stimulate transcription. NF-κB is phosphorylated and is then free to enter the nucleus and bind DNA. NF-κB is a kinase that phosphorylates a transcription factor that binds DNA and promotes protein production. Apoptosis can occur in a cell when the cell is ________________. damaged b. no longer needed c. infected by a virus d. all of the above 14. What is the effect of an inhibitor binding an enzyme? a.
