Mitochondrial Reactive Oxygen Species Production (mROS Production)
- Target
- mROS Production
- Molecular classification
- Biological Process, Oxidative Stress Pathway
01
Overview
Mitochondrial reactive oxygen species (ROS) production refers to the generation of highly reactive molecules derived from oxygen within mitochondria, primarily as by-products of cellular respiration. The main ROS produced are superoxide and hydrogen peroxide, which play dual roles in both physiological signaling and pathological damage. Excessive or dysregulated production leads to oxidative stress, contributing to pathologies such as atherosclerosis, ischemia/reperfusion injury, neurodegeneration, and aging-related diseases. Mitochondria possess robust antioxidant systems to regulate mROS levels under physiological conditions.
