NEET Biology question

Study carefully the following statements and select the incorrect ones. (i) When fats are used in respiration, the RQ is more than unity because fats contain more O2 and require relatively less amount of O2 for oxidation. (ii) The most important energy carrier is ATP. This energy rich compound is mobile and can pass from one cell to another. (iii) Before pyruvic acid enters Krebs' cycle, one of the two carbon atoms of pyruvic acid is reduced to carbon dioxide in the reaction called reductive carboxylation. (iv) A special electron carrier system located in the mitochondrial membrane is called the shuttle system. It transfers electrons from the hydrogens of cytoplasmic NADH to the mitochondrial electron carriers across the mitochondrial membrane. (v) Zymase is a complex mixture of many enzymes which requires several coenzymes for its action. The enzyme complex zymase catalyses a series of reactions taking place during fermentation, leading to the production of ethyl alcohol.
