Solution


Q.

Which of these statements is incorrect                [2018]
1 Enzymes of TCA cycle are present in mitochondrial matrix.  
2 Glycolysis occurs in cytosol.  
3 Glycolysis operates as long as it is supplied with NAD that can pick up hydrogen atoms.  
4 Oxidative phosphorylation takes place in outer mitochondrial membrane.  

Ans.

(4)

Oxidative phosphorylation is the synthesis of energy-rich ATP molecules with the help of energy liberated during oxidation of reduced coenzymes (NADH, FADH2) produced in respiration. The enzyme required for this synthesis is ATP synthase. It is located in F1 or head piece of F0-F1 or elementary particles present on the inner mitochondrial membrane.
