Question

P53 can trigger apoptosis if certain cell cycle events fail. How does this regulatory outcome benefit a multicellular organism?

a) Eliminates damaged cells
b) Promotes cell division
c) Enhances metabolism
d) Induces inflammation

Answer 1

p53 triggers apoptosis to eliminate damaged cells in a multicellular organism.

Step-by-step explanation:

When certain cell cycle events fail, the protein p53 can trigger apoptosis, which is programmed cell death. This regulatory outcome benefits a multicellular organism by eliminating damaged cells. By removing cells that are potentially harmful or incapable of functioning properly, apoptosis helps maintain the overall health and functionality of the organism.
