What happens when Ras proteins become stuck in their "on" state?
A) Cellular responses are slowed down.
B) Additional ions are catalyzed.
C) There is unregulated cell division.
D) There is an increase in protein synthesis.
E) Ligand-gated channels close off the membrane.
Ras Proteins
A family of proteins involved in transmitting signals within cells, playing key roles in cell growth and development.
Unregulated Cell Division
Abnormal cell growth that can lead to tumors and cancer, characterized by the uncontrolled proliferation of cells.
- Separate the roles of signaling molecules from those of pathways in facilitating communication among cells.

Final Answer :
C
Explanation :
Ras proteins are involved in transmitting signals within cells that promote cell division. When Ras proteins are stuck in their "on" state, they continuously signal cells to divide, leading to unregulated cell division, which can contribute to the development of cancer.
