(a)
Interpretation:
The effect in the rate of an enzyme-catalysed reaction has to be determined if temperature is decreased from
Concept Introduction:
Enzyme:
- It is a protein or a molecule which can act as a catalyst for a biological reaction.
- Does not affect the equilibrium point of the reaction.
- Active site of the enzyme is the region where the reaction takes place.
- Enzyme’s activity can be specific which means the activity is limited to a certain substrate and a certain type of reaction and it is referred to as specificity of the enzyme.
Factors affecting enzyme activity:
Substrate concentration
Enzyme concentration
Temperature
(b)
Interpretation:
The effect in the rate of an enzyme-catalysed reaction has to be determined if a drop of dilute
Concept Introduction:
The competition of an enzyme can be reversible or irreversible and in reversible inhibition, the inhibitor can leave and in irreversible inhibition, the inhibitor remains permanently bound.
Reversible Competitive inhibition: It is a type of inhibition occurs when the inhibitor resembles very much to the substrate and thus prevents the substrate binding.
Irreversible competitive inhibition: It is a type of inhibition in which an inhibitor forms covalent bonds to the active site and thereby permanently blocking it.
(c)
Interpretation:
The effect in the rate of an enzyme-catalysed reaction has to be determined if oxidising agent such as

- Explain how the following changes affect the rate of an enzyme-catalyzed reaction in the presence of an uncompetitive inhibitor: (a) increasing the substrate concentration at a constant inhibitor concentration, (b) decreasing the inhibitor concentration at a constant substrate concentration.arrow_forwardWhich of the following is true under the following conditions: an enzyme displaying Michaelis-Menten kinetics where the enzyme concentration is 10 nM, the substrate concentration is 45 mM, and the Km is 50 µM? a) The enzyme has low catalytic efficiency for the substrate. b)The rate of catalysis is near half-maximal velocity. c)The enzymatic reaction is near maximal velocity. d)Halving the substrate concentration has little effect on the catalytic rate. e) There is not enough information provided.arrow_forwardb) Enzymes accelerate reactions by facilitating the formation of the transition state. Define transition state and activation energy. For full credit, you need to present the actual graph (for an endergonic or exergonic reaction - make sure to specify your choice) highlighting each term? c) Explain how an irreversible inhibitor for an enzymatic reaction differs from reversible inhibitors. Provide specific example of an irreversible inhibitor and its target enzyme d) Determine the Vo as a function of Vmax when the substrate concentration is equal to 10 KM or 20 KM. What does this tell you about an enzyme ability to reach Vmax?arrow_forward
- For the following two scenarios, sketch the complete reaction free energy diagram for an enzyme-catalyzed conversion of a single substrate (S) into product (P), where the reaction is spontaneous in the forward direction. For each of these, overlay the free energy diagram for the uncatalyzed reaction and indicate AAG" on your sketch: a). Substrate binding is rate limiting b). The chemical step is rate limitingarrow_forwardGiven the following enzyme-catalyzed reaction, identify the class and subclass of the enzyme involved.

It has three other parts as well, A) Which Enzyme Catalyzes this reaction? choices are in image provided. B) What is ∆G°' for this reaction? Answer in Joules. K' = 19 C) If the concentration of Glucose-1-phosphate is 48.82 µM at equilibrium, what is the concentration of Glucose-6-phosphate in µM?

Pay attention to units. Round to the correct number of significant figures. There are 103 µM in 1mM. Thank you and you are the winner for Genius of the day!!arrow_forward
- Consider the enzyme pancreatic amylase, which has an optimum pH of 7.0. How is the rate of a pancreatic amylase-catalyzed reaction affected by each of the following changes: (a) lowering the pH from 7 to 4; (b) increasing the pH from 7 to 9; (c) decreasing the temperature from 37 °C to 28 °C; (d) increasing the temperature from 37 °C to 50 °C?arrow_forwardYou will perform the protocol below for the calf intestinal alkaline phosphatase (CIP) provided. For each reaction, your final enzyme concentration should be 10 nM CIP. Note: Enzymes purchased are typically labelled with their “units of activity” (U), as this relates to how much enzyme is needed to catalyze a reaction. The 100 nM CIP provided has approximately 3 U/mL and was diluted 1 in 1,000 from a 500 U/mL purchased enzyme. 1) Create a table (similar to the one below) to help you determine and keep track of what to add to each of the cuvettes in which your reactions will be measured. The five different concentrations of PNPP should be: 25, 50, 100, 200, 300 μM. Each reaction will be in a final volume of 1 mL and contain 10 nM alkaline phosphatase.

- When enzyme solutions are heated, there is a progessive loss of catalytic activty over time due to denaturation of the enzyme. A solution of the enzyme hexokinase incubated at 45 degrees Celsius lost 50% of its activity in 12 minutes, but when incubated at 45 degrees Celsius in the presence of a very large concentration of one of its substrates, it lost only 3% of its activity in 12 minutes. Suggest why thermal denaturation of hexokinase was retarded in the presence of one substrates.arrow_forwardWhich of the following is TRUE under the following conditions: the enzyme concentration is 2.5 nM, substrate concentration is 75 nM, the KM = 150 nM, and the Vmax = 20 nmol/min a) The rate of the reaction is 20 nmol/min! b) The rate of the reaction is between 10 nmol/min and 20 nmol/min. c) The rate of the reaction is 10 nmol/min. d) The rate of the reaction is below 10 nmol/min. e) The rate cannot be determined from the above information.arrow_forwarda) Based on the data shown in the image, what are the Km and Vmax for the enzyme with L-DOPA and D-DOPA?
