Which mechanism explains why damaged mitochondria trigger cellular self-destruction (apoptosis)?

💡 Explanation

Cytochrome c release from damaged mitochondria activates caspase enzymes, initiating apoptosis because this intrinsic pathway signals irreversible cellular damage, therefore the programmed cell death removes potentially harmful cells, rather than allowing them to survive with compromised function.

• If a small group of finches colonizes a remote, previously uninhabited island, which evolutionary outcome becomes more pronounced?
• If a signaling molecule permanently disrupted a nuclear hormone receptor's ability to dimerize, which consequence follows?
