WebA. All excess hydrogen ions are removed from the body in the urine. B. Buffer systems consist of a weak acid and its conjugate weak base which function to resist large swings in pH. C. When a strong base is added to a solution, the buffer system's weak acid releases its hydrogen ions to bind the base ions. D. Web(a) acids that can leave solution and enter the atmosphere, such as carbonic acid, are volatile acids. (b) Acids that do not leave solution, such as sulfuric acid, are fixed acids.

WebAs carbonic acid dissociates, H+ are buffered by hemoglobin proteins. At the lungs, the reaction sequence is reverse and CO2 diffuses into alveoli for exhalation. What is the protein buffer system? In both immersion and perfusion fixation processes, chemical fixatives are used to preserve structures in a state (both chemically and structurally) as close to living tissue as possible. This requires a chemical fixative. Crosslinking fixatives act by creating covalent chemical bonds between proteins in tissue. This anchors soluble proteins to the cytoskeleton, and lends additional rigidity to the tissue. Preservat…

Lactic acid, … WebBuffers typically consist of an acid-base pair, with the acid and base differing by the presence or absence of a proton (a conjugate acid-base pair). For instance, one of the buffers that maintain the pH of human blood involves carbonic acid (H _2 2 CO _3 3) and its conjugate base, the bicarbonate ion (HCO _3 3 ^- − ).
