How Buffers Help to Regulate Body pH
Good evening class and professor!
I chose to discuss topic 2 this week. The topic is Discuss how buffers help to regulate body pH.
The pH level in the blood is maintained by the kidneys and the lungs. The pH level on the blood should be at 7.4. In order for the kidneys and lungs to maintain this pH level it affects the buffers in the blood. The buffer is a substance that is resistant to the change in the body’s pH level. Basically the buffers can make an acid or base less potent and try and neutralize it so the body is not overly acidic or basic. When these buffers attach to the acidic molecule they act to reduce how strong that molecule is. When the buffers attach to the base molecules it does the same thing to try and lower the strength of the base. All in all the buffers work to keep both acids and bases at a neutral level.
One other thing that should be noted, when your body is put into motion (exercise) it speeds up your metabolism. When your metabolism is sped up it increases the production of CO2 and Hydrogen in the muscles. When your body is producing these two it causes the lactic acid to be released into your blood. When this acid is put into your blood stream it can drastically change the pH level in your body. As stated above, your pH level should be 7.4; if your pH level is dropped below 6.8 it can be extremely dangerous to your health.
All in all, the pH buffers in your body work to reduce the lactic acid in your blood. This process allows your body’s pH level to stay at a healthy safe level.
Hope everyone has a great week!!

    In general, if the acid is not extremely weak, the pH of a solution of a weak acid is governed by the concentration of the acid and Ka. Under similar conditions, the pH of a solution of a weak base is determined by the concentration of the weak base and Kb. In solutions containing both a weak acid and a strong acid, both acids play a role in determining the pH of the solution; however, if the concentration of the strong acid is relatively large, it will inhibit the dissociation of the weak acid.(the common-ion effect). The pH of this solution would then be calculated as if the weak acid were not present! (Likewise, in a solution containing both a strong base and a weak base, the strong base concentration would be used to calculate pH.) Buffer solutions contain both a weak acid and its conjugate weak base in appreciable concentrations. Within limits, these solutions tend to resist changes in pH upon addition of either H3O+ or OH- (because these species are largely consumed by the acidic and basic components of the buffer mixture). In buffer systems like NaC2H3O2-HC2H3O2 mixtures, the principal source of the acetic acid molecule is from the acid; the principal source of the acetate ion is from the salt. Therefore, the [H3O+] is determined by the salt/acid (or equivalently, the base/acid) mole ratio. For a conjugate acid/base pair: pH = pKa + log10 [nconjugate base] [nacid]…

    Lactic Acid will be accumulated in the athlete’s muscles during a ‘high intensity’ part of the race. This will interfere with contractile proteins of the muscle which will cause fatigue. There are several ways in which Lactic Acid can be removed from the body during the onset of exercise. Two ways in which Lactic Acid can be removed are as follows:…

    The breakdown of CP releases energy, which catalyzes a reaction to produce ATP. The production of more ATP allows movement of the muscle to continue. Lactic acid is a product of glycolysis created by the breaking down of pyruvate.

Lactic acid is then disassociated to produce lactate. When lactic acid (C3H6O3) releases a hydrogen ion (H+), the remaining compound binds to a sodium ion (Na+) or a potassium ion (K+) to form a salt. It is this salt that is lactate. Now the cell contains a lactate compound and a free H+ for each compound of lactic acid that is produced. It is this increase in cellular H+ that causes the pH to decrease, becoming more acidic. The acid in the muscle causes the fibers' calcium-binding capacity to decrease, thus limiting muscle contraction. This is the cause of muscle fatigue.

Some of the lactate seeps out of the cell into the bloodstream where it is sent to the liver to be used to synthesize glucose. The remainder of the lactate must be eliminated in the cell. Oxygen and cellular lactic acid act together to resynthesize ATP via anaerobic metabolism.

The question many athletes want answered is how can I prolong my muscle fatigue? Theoretically, if you can decrease the amount of acid build-up produced in…
