In acid-base balance, the kidney is responsible for 2 major activities: 1  Reabsorption of filtered bicarbonate: 4,000 to 5,000 mmol/day. 2  Excretion of the fixed acids (acid anion and associated H +): about 1 mmol/kg/day..4.3 Bicarbonate Reabsorption. Daily filtered bicarbonate equals the product of the daily glomerular filtration rate (180 l/day) and the plasma bicarbonate concentration (24 mmol/l). This is 180 x 24 = 4320 mmols/day (or usually quoted as between 4000 to 5000 mmols/day).
Mixing water and sugar produces a mixture that is called a solution. In chemistry labs, this is often an experiment used to demonstrate the solubility of a solute in a solvent. In this experiment, the solute is sugar, and water is the solvent. Continue Reading. To form the solution, sugar dissolves in a glass of water.
If you can join two simple sugars into a compound one, then it should be possible to split them back up again. This is the process we call digestion. The body uses proteins called enzymes to do this. The enzyme that splits lactose is called lactase.
