Final electron acceptor of anaerobic respiration is______

What is tha ration of ATP synthesis in aerobic and anaerobic cellular respiration?

What is the final acceptor of electrons in aerobic respiration ? From which complex does it receive electrons ?

Photons of energy 3.55 eV each are incident on a metal surface whose work function is 1.9 eV. What is the maximum K.E with which an electron is ejected form tis surface ?

Refer to the following flow chart representing the cellular respiration and its fuels. Blanks 1,2,3,4,5,6 and 7 are respectively

Study carefully the following statements and select the incorrect ones. When fats are used in respiration, the RQ is more than unity because fats contain more O_(2) and require relatively less amount of O_(2) 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 enter 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 shuttle system. It transfers electron 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 series of reaction taking place during fermentation leading to the production of ethyl alcohol.
