Front (Question)

Where do inorganic ions exist

Back (Answer)

Inorganic ions occur in solution in the cytoplasm and body fluids of organisms

#3
Front (Question)

Iron in haemoglobin

Back (Answer)

Each polypeptide chain is associated with a haem group Includes a Fe2+ iron ion Enables binding and transport of oxygen as oxyhaemoglobin

#4
Front (Question)

Ions in membrane transport

Back (Answer)

Sodium-potassium pumps (Na+/K+-ATPase) Couples ATP hydrolysis with movement of sodium and potassium ions Co-transport of glucose and amino aicds with Na+ ions into the epithelium cells during absorption Maintains osmotic balance Maintains membrane potential

#5
Front (Question)

Hydrogen ions

Back (Answer)

Establish proton gradients ATP sypthase couples H+ ions movement with ATP formation Determines solution pH Concentraion of a solution (Too high can denature enzymes)
