Many enzymes require iron for appropriate function. However, dysregulation of intracellular iron homeostasis produces excessive reactive oxygen species (ROS) via the Fenton reaction and causes devastating effects on cells, leading to ferroptosis, an iron-dependent cell death. In order to protect against harmful …
WebbFigure 5.17 Proton Gradient provides energy for a secondary active transporter. The proton pump creates an electrochemical gradient of protons (hydrogen ions, H+) using ATP to drive primary active transport. This gradient allows for cotransport/secondary transport of sucrose against its concentration gradient as protons come down their concentration … WebbIons are atoms or groups of atoms that gain an electrical charge by losing or acquiring electrons. For example, in the reaction that forms salt from sodium and chlorine, each sodium atom donates an electron, which is negatively charged, to a chlorine atom.
Electrolytes are essential for basic life functioning, such as maintaining …
