BIOL 3070 Lecture Notes - Lecture 17: Intracellular Ph, Metabolic Waste, Osmotic Concentration
Document Summary
Ammonetelic organism removes the nitrogenous wastes in he form of ammonia due to the excess of water: ammonia is the most toxic. It is very soluble: aquatic and terrestrial animals release nitrogenous wastes in the form of ammonia. Very soluble, plays a role in the osmolarity and can be used in maintaining osmolarity to match the osmolarity of the surrounding environment. Ph= -log [h+: thus changing one ph 10 fold more h, usually the average normal ph is 7. 35-7. 45. Below 6. 8 and above 8 death. Intracellular ph = 7. 0 due to higher concentration of carbon dioxide. Acid base balance: ph is different in different tissue depending on its function stomach is acidic. Urine is acidic or basic depending on the organism demands (getting rid of intestine is alkaline protons or getting rid of base in the form of bicarbonate) Abnormalities in ph: acidosis: ph less 7. 35.
