In which of the following cases can E° be equal to zero?
I.In any cell at equilibrium
II.In a concentration cell
III.E° can never be equal to zero.
Phosphorylated Intermediate
A molecule that has been temporarily phosphorylated (had a phosphate group added) during a metabolic reaction, often playing a crucial role in energy transfer.
Electron Transport
A series of chemical reactions that transfer electrons from electron donors to electron acceptors via redox reactions and couples this electron transfer with the transfer of protons (H+ ions) across a membrane.
Proton Gradient
A gradient of hydrogen ions across a membrane, often used in the process of generating ATP in cells, particularly within the mitochondria during cellular respiration.
Aerobic Respiration
A metabolic process that converts oxygen and glucose into energy in the form of ATP, water, and carbon dioxide, taking place in the mitochondria.
