How do halogenoalkanes typically react? - correct answer By nucleophilic substitution How do halogenoalkanes react under different conditions? - correct answer By elimination How does elimination reactions occur? - correct answer A hydrogen halide is eliminated from the molecule, leaving a double bond in its place so that an alkene is formed What is the OH- ion from aqueous sodium or potassium hydroxide? - correct answer A nucleophile and its lone pair will attack a halogenoalkane at C

AAMC 4 Bio question with complete solution 2023/2024Most cytochrome P450 enzymes alter the activity of drugs by: - correct answer oxidizing them *Cytochrome P450 acts as monooxygenases, where an oxygen atom is inserted into a substrate (the drug of interest), thereby resulting in the oxidation of the substrate. - MISSED - was between reduced and oxidized; remember it is a monoxygenase During phosphorylation of STAT5b proteins, phosphate groups are exchanged for what atoms on tyrosine resi...

In the reaction catalyzed by pyruvate carboxylase (the first reaction in gluconeogenesis), CO 2 is - activated by ATP enegy What is the metabolic logic that explains why liver cells contain the enzyme glucose-6-phosphatase but muscle cells do not? - The reason G-6-P is highly available in the liver is because that is where gluconeogenesis (which produces G-6-P) and glycogenolysis take place. glugoneogenesis needs the enzyme glucose-6-phosphotate, which is not found in muscle tissue. McArd...
