NEETBotanyRespiration in Plants
Which of the following pairs of a metabolic reaction and its primary cellular location is incorrectly matched?
Options
- AConversion of pyruvate to acetyl CoA : Mitochondrial matrix
- BConversion of 3-phosphoglyceric acid to 2-phosphoglycerate : Cytoplasm
- COxidation of succinate to fumarate : Mitochondrial matrix
- DReduction of oxygen to water : Inner mitochondrial membrane
Correct answer
C. Oxidation of succinate to fumarate : Mitochondrial matrix
Step-by-step solution
The conversion of pyruvate to acetyl CoA is the link reaction catalysed by pyruvate dehydrogenase, which takes place in the mitochondrial matrix. The conversion of 3-phosphoglyceric acid to 2-phosphoglycerate is a step of glycolysis, which occurs in the cytoplasm. The reduction of oxygen to water occurs at Complex IV of the electron transport system, which is located in the inner mitochondrial membrane. The oxidation of succinate to fumarate is catalysed by the enzyme succinate dehydrogenase. Unlike other enzymes o
