Answer:
(B). inhibiting HMG-CoA reductase.
Explanation:
Lovastatin is a drug, which is used to reduce risk for cardiovascular diseases and to reduce level of cholesterol in blood.
It works by inhibiting HMG-CoA reductase (3-hydroxy-3-methylglutaryl-coenzyme A reductase) enzyme, required for the formation of mevalonate from HMG-CoA.
Mevalonate is building block for the biosynthesis of cholesterol. Hence, lovastatin inhibits cholesterol production by inhibiting synthesis of mevalonate.
Thus, the correct answer is option (B).
E, Two large and four small is the correct answer
the digestive and circulatory are the two systems that get nutrients to the bone cells
Blood PC02 may be measured by using direct spectrophotometer
Explanation:
Blood gas analysis or arterial blood gas (ABG) test is done to determine blood pH and the amount of oxygen and carbon dioxide dissolved in arterial blood.
Blood PCO2 is the partial pressure of carbon dioxide dissolved in the arterial blood.
ABG or oximetry test is done by using direct spectrophotometry in a spectrophotometer and gas analysis is done by calorimetric methods. Spectrophotmetry is highly used in Medicine to perform quantitative analysis of blood and its composition. The spectrophotometer measures the light intensity or wavelengths absorbed by the sample solution.
Blood PCO2 reflects the degree of exchange gases in and out of the lungs. An increase in PCO2 levels indicates respiratory illnesses like obstructive lung diseases or pulmonary edema; while a decrease indicates conditions like hypoxia, pulmonary embolism, hyperventilation etc.
