Snyder CM, Chandel NS (2009) Antioxid Redox Signal

Abstract: Mitochondria can initiate cell death or activate genes that promote cell survival in response to low oxygen. The BCL-2 family of proteins regulate cell death in response to anoxia (0-0.5% O2). By contrast, under hypoxia (0.5-3% O2), mitochondrial oxidative stress activates hypoxia-inducible factors (HIFs) to promote cell survival. In this review, we discuss how mitochondria, BCL-2 proteins, and HIFs are crucial for cellular responses to low oxygen.

Correction: FADH₂ and Complex II

FADH₂ is shown as the substrate feeding electrons into Complex II (CII). This is wrong and requires correction - for details see Gnaiger (2024).
