FAQ
Frequently Asked Questions
Yes, these terms are essentially synonymous in biochemistry, though 'electron transport chain' is sometimes considered slightly more general.
In eukaryotic cells, it's embedded in the inner mitochondrial membrane.
It leads to reduced ATP production, which can cause fatigue, organ dysfunction, and is associated with various metabolic diseases.
No, oxygen is the final electron acceptor in the chain, so aerobic conditions are required for its complete function.
