Significance of Cytochrome c
Cytochrome c is a mitochondrial protein that plays a critical role in the apoptotic pathway. It is released from mitochondria during ischemia/reperfusion (I/R) injury, leading to the activation of caspases, which trigger apoptosis in cells such as HCT116 and HT-29. Its release signals the up-regulation of apoptotic processes, and it functions within the electron transport chain. Overall, cytochrome c is central to the mechanisms of programmed cell death.

The concept of Cytochrome c in scientific sources
Cytochrome c is a crucial protein residing in the mitochondrial intermembrane space, playing a dual role in apoptosis by activating caspases and functioning within the electron transport chain, with its release triggering cell death.
