1. What is the equation for: 1. Sensitivty? 2. Specificity? 3. PPV? 4. NPV? 5. Accuracy?

Anaerobic glycolysis When O2 deman of skeletal muscle exceeds ability of heart/lungs to provide oxygen muscles swithc to anaerobic glycolysis where pyruvate produced is reduced to lactate by the action of lactate dehydrogenase as NADH is oxidized. Lactate is release into the blood stream causing metabolic acidosis with high anion gap.
1. Oxaloacetate which is made by pyruvate carboxylase Oxaloacetate is used in TCA. Pyruvate levels rise since pyruvate isnt converted to oxaloacetate. Then Alanine levels rise. Pyruvate carboxylase is also used in hepatocytes for gluconeognesis so hypoglycemia also results.
1. Sensitivity = TP / (TP + FN) 2. Specificity = TN / (TN + FP) 3. PPV = TP/(TP + FP) 4. NPV = TN/ (TN + FN) 5. Accuracy = (TP + TN) / (TP + FP + TN + FN)
1. Generalized transduction. This is when virus invades a cell replicates and creates a new virion but that new virion does not actually have any phage or virus genetic material but by mistake only has bacterial DNA from its host so that virion will still bind to a new cell and inject its contents but in this case these contents are bacterial DNA which if the new host is capabable of homologous recombination can incorporate into its new genome.
