The mass of the fragment divided by the charge is called mass-to-charge ratio (m/z). Since most fragments have charge of +1, the m/z usually represents the molecular mass of the fragment or the entire compound in the …

Potassium ions bound in the channel are shown in green. All living cells are surrounded by a membrane that separates the watery world inside from the environment … Webb28 apr. 2014 · 1 Answer. Compounds with small ions tend to be less soluble than those with large ions. The solubility of a compound is the result of a competition. The ions in the compound attract each other, and the water molecules attract the ions. If the water molecules have a greater attraction to the ions than ions have for each other, then the …
WebbActive transport mechanisms, collectively called pumps or carrier proteins, work against electrochemical gradients. With the exception of ions, small substances constantly pass through plasma membranes. Active transport maintains concentrations of ions and other substances needed by living cells in the face of these passive changes.
