Discuss the consequences of dysregulated apoptosis in diseases.
Dysregulated apoptosis can lead to cancer, neurodegenerative diseases, and autoimmune disorders due to excessive or insufficient cell death.

Explain how cellular signaling influences apoptosis.
Cellular signaling pathways regulate apoptosis by activating or inhibiting pro-apoptotic and anti-apoptotic proteins.

Explain the mitochondrial pathway of apoptosis.
The mitochondrial pathway involves the release of cytochrome c from mitochondria, activating caspases.

Differentiate between the intrinsic and extrinsic pathways of apoptosis.
The intrinsic pathway is triggered by internal signals (e.g., DNA damage), while the extrinsic pathway is activated by external signals (e.g., death ligands).

What role do caspases play in apoptosis?
Caspases are proteases that execute apoptosis by cleaving specific cellular substrates.

Describe the inflammatory response associated with necrosis.
Necrosis triggers an inflammatory response characterized by immune cell recruitment and release of pro-inflammatory cytokines.

List two key differences between necrosis and apoptosis.
Necrosis is uncontrolled and causes inflammation; apoptosis is controlled and does not cause inflammation.
