Enzymes Temperature is an important factor that can regulate enzyme-mediated functions. Temperature is one of the tightly homeostatically controlled variables in the human body. What are the symptoms of loss of temperature control during a high fever? Explain why these symptoms occur based on enzyme function and cell signaling effects that are dependent on temperature. Based on Figure 1, explain how the temperature optimum of the activity of enzymes is expected to differ in organisms depending on where they live....

An enzyme-catalyzed reaction is carried out in a 100 mL solution containing 0.1 M TRIS buffer. Th pH of the reaction mixture at the start was 8.0. As a result of the reaction, 0.002 mol of H^+ were produced. What is the ratio of TRIS base to TRIS acid at the start of the experiment? What is the ration at the end of the experiment? What is the final PH?

Under what circumstances does an enzyme catalyzed reaction rate resemble a non-enzyme catalyzed reaction? At very low concentrations of substrate (Km is greater than S) the Michaelis-Menton equation can be simplified to? At very high concentrations of substrate, the Michaelis-Menton equation can be simplified to? How do you determine the initial rate of reaction

An enzyme-catalyzed reaction was carried out in 5 ml of a 0.05 M phosphate buffer, pH 6.90. As a result of the reaction, 0.01 mole/liter of H+ was produced. a) What were the concentrations of each form of the buffer at the start of the reaction? b) What was the pH at the end of the reaction? c) Was this an appropriate buffer for this experiment? Why?
