A pharmaceutical company is testing a new enzyme-targeted drug designed to enhance metabolism in patients with a rare metabolic disorder. Before testing in humans, researchers performed in vitro experiments to study how the enzyme’s activity changes under different physiological conditions, including temperature, pH, and salinity. The table below summarizes the relative enzyme activity under various experimental conditions: Analyze the table and select all correct statements regarding Temperature Effects:

A new drug is being tested to regulate the activity of an enzyme involved in cholesterol metabolism. During laboratory studies, researchers observe the following: Drug A binds to the enzyme temporarily at the active site and can be displaced by high substrate concentrations. Drug B binds covalently to the enzyme and permanently blocks its active site. Predict enzyme activity in the presence of high substrate concentration (all that apply)

A new drug is being tested to regulate the activity of an enzyme involved in cholesterol metabolism. During laboratory studies, researchers observe the following: Drug A binds to the enzyme temporarily at the active site and can be displaced by high substrate concentrations. Drug B binds covalently to the enzyme and permanently blocks its active site.   Identify the type of inhibition (all that apply):
