Arterial Blood Gas Interpretation (ABG) Arterial Blood Gas Analysis is used to measure the partial pressures of oxygen (PaO2)‚ carbon dioxide (PaCO2)‚ and the pH of an arterial blood sample. Oxygen content (O2CT)‚ oxygen saturation (SaO2)‚ and bicarbonate (HCO3-) values are also measured. A blood sample for ABG analysis may be drawn by percutaneous arterial puncture from an arterial line. The ABG analysis is mainly used to evaluate gas exchange in the lungs. It is also used to assess integrity of

optimal ranges under which the enzyme activity is maximized. Also to determine whether saline and alcohol are inhibitors or activators Hypothesis: PH factor prediction: I predict that as the pH increases so the activity of the enzyme will increase until it reaches optimum pH range (pH 7) because the enzyme is less denatured when it reaches the preferred pH level‚ and after this it will decrease because the active site will change in shape and it will no longer accept substrates.

Chapter I Introduction A.) Background of the Study: The Acids‚ bases and salts in the pH range are among the most important chemical compounds used by chemists. For instance‚ hydrochloric‚ phosphoric and citric are acids used to make mineral stain removers‚ toilet bowl cleaners‚ metal cleaners and rust removers. A variety of maintenance chemicals contain these compounds. Alkali maintenance chemicals like degreasers‚ oven cleaners and drain openers contain bases such as Sodium Hydroxide (NaOH)

Reetika Kashyap September 20th‚ 2012 Enzyme Lab What is an enzyme? Enzymes are specialized protein molecules simplifying most of the body’s metabolic processes such as‚ supplying energy‚ digesting foods‚ purifying your blood‚ executing the body of waste products etc. Enzymes act as catalyst by speeding up the reactions that happen in our bodies and decreasing the amount of activation energy needed to break a complex down. A reactant is any given enzymatic reaction is called a substrate for that

Conditions of Temperature‚ pH‚ Boiling and Competitive Inhibitors By Robin Caserta BIO 101 September 30‚ 2013 ABSTRACT The enzyme‚ peroxidase‚ extracted from a turnip was tested for its efficiency in binding to its substrate and its stability under several conditions. To do this‚ we tested effects on peroxidase activity‚ first‚ with different amounts of the enzyme‚ next at temperatures of 4oC‚ Room Temperature‚ 32oC‚ 48oC and boiling; then‚ at pH 3‚ pH 5‚ pH 7 and pH 9; and‚ finally‚ with the

The effects on water from the NaOH are that it started with a 4 pH than went up to a 7 pH and it started to just keep the same pH. 2. The average pH change for the 30 drops of HCl added to the biological material is 4.3. 3. The average pH change for the 30 drops of NaOH added to the biological material is 8.3. 4. (Q2/Q3)

oxides CO₂‚ SO₂ and NO₂ by using data that was collected using a pH sensor which was connected to a laptop with LoggerPro and Vernier. We created the gases by bubbling each gas into the water to create the three acidic solutions we were looking for. Once that step was completed‚ the pH levels of all three solutions were compared to each other to see the different strengths of each solution. As a result we found that NO₂ had the highest pH level change out of all the three gasses that we collected.

amount 0.1 M NaOH used to lower/raise the pH of a blood buffer. In this experiment‚ HCl (a strong acid) and NaOH (a strong base) are used as examples of strong acids/bases‚ and the titration with H2PO4 shows the effect on a buffer solution. The assumption was the addition of large amounts of HCl will lower the pH‚ while the addition of large amounts of NaOH will increase the pH‚ while small amounts of either strong acid or base will not affect blood pH because of the buffer in blood.
