Molecule often produced by a microorganism to kill other microorganisms that might compete for the same food source? It usually works by dissipating essential electrochemical gradients in the competing organism.

Bacteriocin

Explanation:

Bacteriocin is a ribosomally synthesized compounds produced by bacteria that are active against closely related bacteria

Bacteriocin consists of 20-60 amino acidsMost bacteriocin target cell membranes while some inhibit the biosynthesis of biopolymersBacteriocin dissipate the proton motive force by disrupting the pH gradient of disruptive cells,they do so by forming pores in the target cellsPore formation ultimately results in the leakage of inorganic phosphates and an ionic imbalance;The initial disturbance causes dissipation of the proton motive force which encompasses a complete or partial dissipation of either or both the electrochemical gradient and the transmembrane potential

U. life is what you go through to become a better person. it makes you stronger, wiser, and more creative. it can be hard but its ok. because i believe everyone was put here for a reason. whether or not you know that reason you should always look towards the future and trust in god for a better tomorrow.be safe and blessed
