Apoptosis occurs in all but one of the following situations
A. embryogenesis.
B. bacterial infection.
C. menstruation.
D. tumours.
E. viral infection
The correct answer is B. bacterial infection.
Apoptosis occurs in the following situations:
A. Embryogenesis: Apoptosis plays a crucial role in shaping tissues and organs during development.
C. Menstruation: Apoptosis helps eliminate the uterine lining during menstruation.
D. Tumors: Apoptosis can occur in tumor cells, and its dysregulation can contribute to cancer development.
E. Viral infection: Apoptosis can be triggered by viral infections to eliminate infected cells.
However, apoptosis is not typically triggered by bacterial infections (B). Instead, bacterial infections often induce necrosis or pyroptosis, which are different forms of cell death. Pyroptosis is a pro-inflammatory form of cell death that helps eliminate bacterial infections.
Note that while apoptosis doesn’t typically occur in response to bacterial infections, some bacterial toxins can induce apoptosis in specific contexts. Nonetheless, the primary response to bacterial infections involves other forms of cell death and immune responses.
