A) Alcoholic fermentation
B) Photorespiration
C) Lactate fermentation
D) Aerobic respiration
Correct Answer: A
Solution :
: Alcoholic fermentation comprises a series of biochemical reactions by which pyruvate (the end product of glycolysis) is converted to ethanol and carbon dioxide. It is the basis of the baking and brewing industries. In this process, sugar \[({{C}_{6}}{{H}_{12}}{{O}_{6}})\] first breaks into pyruvate (by the process of glycolysis), which is then converted ethanol \[({{C}_{2}}{{H}_{5}}OH)\] and \[C{{O}_{2}}\]. The whole process is expressed as : \[\underset{(Glu\cos e)}{\mathop{{{C}_{6}}{{H}_{12}}{{O}_{6}}}}\,+2NA{{D}^{+}}+2ADP+2{{P}_{i}}\to \] \[2Pyruvate+NADH+2ATP+2{{H}^{+}}\] \[Pyruvate\xrightarrow[decarboxylase]{Pyruvic\,acid}\to \underset{(acetaldehyde)}{\mathop{C{{H}_{3}}CHO}}\,+C{{O}_{2}}\] \[C{{H}_{3}}CHO+NADH+{{H}^{+}}\xrightarrow{alcohol\,dehydrogenase}\] \[\underset{(ethyl\,alcohol)}{\mathop{{{C}_{2}}{{H}_{5}}OH}}\,+NA{{D}^{+}}\]You need to login to perform this action.
