quantities of potassium. In contrast to the ECF fluid‚ the ICF contains small amounts of sodium‚ chloride‚ and bicarbonate and large amounts of potassium ← The cell membrane serves as the primary barrier to the movement of substances between the ECF and ICF compartments. Lipid-soluble substances such as gases (i.e.‚ oxygen and carbon dioxide)‚ which dissolve in the lipid bilayer of the cell membrane‚ pass directly through the membrane. Many ions‚ such as sodium (Na+) and potassium (K+)‚ rely

Vitamin C 1. Vitamin C is a required vitamin for the synthesis of collagen‚ norepinephrine‚ and carnitine. Collagen is a crucial component in the structure of blood vessels‚ tendons‚ ligaments‚ and bone. Norepinephrine is a neurotransmitter which is critical for proper brain function. Carnitine is a small molecule that is essential for transporting fat into the mitochondria of cells to be later converted into energy. Vitamin C is also used as a highly effective antioxidant to help protect key

toothpaste or you can use the banana peel first and then brush. Use a ripe banana as it has the most potassium content in it. Peel from the bottom end as this is how monkeys peel their bananas and it will keep you from having all those loose threads. * 2 Take a piece of the inside of the banana peel and gently rub around on your teeth for about 2 minutes. The amazing minerals in the peel like potassium‚ magnesium and manganese absorb into your teeth and whiten them. * 3 Repeat the

Abstract: The experiment was done to demonstrate the effect of ADH on the volume and concentration of urine in order to demonstrate the control of ADH over blood plasma osmolarity. Since non-invasive methods were preferred the volume and concentration of urine was used in place of drawing blood. The results that we our anticipating are that ADH levels in the group of subjects that ingested the 6 gm. Of NaCl would increase over time in response to the increased osmolarity of the blood from all

How does the heat released during the reaction between distilled water and Group 1 elements (lithium‚ sodium and potassium) vary as one goes down the group? OBJECTIVE The objective of the experiment is to measure the heat change during the reactions with minimal heat loss to the surroundings. MATERIALS The materials to be used in this experiment are: • Lithium‚ sodium‚ and potassium metal are the three Group 1 elements and reactants. • Distilled water is a reactant. • 250ml beaker to measure
