Every organism needs energy, and most use oxygen to generate this. In humans, this happens in our cell’s batteries: mitochondria! 🔋 Normally, the process where cells create energy (oxidative respiration) occurs on a super physical scale - every tiny cell has a complete set of energy-making proteins. That’s not true for the cable bacteria, they stretch this process over thousands of cells - becoming literal live wires! #bacteria #microbiology #biology #biologylovers | MinuteEarth
