Which one of the following enzymes is located in the outer mitochondrial membrane?
Show Hint
- Citrate synthase
- Fumarase
- Monoamine oxidase
- Succinate dehydrogenase
The Correct Option is C
Solution and Explanation
Certain enzymes are located in specific parts of the mitochondria, such as the inner membrane, outer membrane, or matrix. Monoamine oxidase (MAO) is an enzyme found in the outer mitochondrial membrane.
Step 2: Analyze the options.
- (A) Citrate synthase: This enzyme is located in the mitochondrial matrix, not the outer membrane.
- (B) Fumarase: This enzyme is located in the mitochondrial matrix as well.
- (C) Monoamine oxidase: This enzyme is located in the outer mitochondrial membrane.
- (D) Succinate dehydrogenase: This enzyme is embedded in the inner mitochondrial membrane, not the outer membrane.
Step 3: Conclusion.
The correct enzyme located in the outer mitochondrial membrane is Monoamine oxidase (C).

- The standard free energy changes for conversion of phosphoenol pyruvate (PEP) to pyruvate, and ATP synthesis are shown below. \[ \text{PEP} + \text{H}_2\text{O} \rightleftharpoons \text{pyruvate} + \text{P}_i \quad \Delta G^\circ = -61.9 \, \text{kJ/mol} \] \[ \text{ADP} + \text{P}_i \rightleftharpoons \text{ATP} + \text{H}_2\text{O} \quad \Delta G^\circ = 30.5 \, \text{kJ/mol} \] The starting concentrations of PEP, ADP, pyruvate, and ATP are 25, 25, 50, and 50 mM, respectively. The value of the universal gas constant (R) is 8.315 J·mol\(^{-1}\)·K\(^{-1}\). The actual free energy change in kJ·mol\(^{-1}\) for the reaction \[ \text{PEP} + \text{ADP} \rightarrow \text{pyruvate} + \text{ATP} \] carried out at 37°C will be ________ (rounded off to one place of decimal).
