What structures are formed when water molecules surrounds individual ions

Cations (positively charged ions) are surrounded by the negative dipole of the water molecule and the anions (negatively charged ions) are surrounded by the positive dipole of the water molecule. A lattice structure is formed when water molecules surrounds individual ions.

They form cations.

Explanation:

For example, cations such as Na +, K +, or Mg ++ surround themselves with the water molecules with which they bind through dipole interactions; the oxygen atoms in the water molecule are oriented towards the cation. Other cations like Fe3 + bind to 6 water molecules through very strong bonds.

both anaerobic and aerobic respiration use glucose (or other carbohydrates), proteins and lipids to produce atp and nadh. cell uses those energy molecules, obtained from food and   breaks them down during the chemical reactions of respiration. in anaerobic respiration, nadh is regenerated to nad+ by enzymes lactate dehydrogenase (lactate is produced, e.g. in muscle cells) or by alcohol dehydrogenase where ethanol is produced (alcohol fermentation), while in aerobic respiration, electrons from nadh are deposited in the mitochondria to regenerate nad+ (electron transport chain. anaerobic respiration produces 2 atp per molecule of glucose compared to aerobic respiration where about 38 atp molecules are produced.
