Direction for: In each of the following questions a statement of Assertion is given followed by a corresponding statement of Reason just below it. Of the statements mark the correct answer as
Assertion Glycolysis begins in cytoplasm and yields two molecules of pyruvate. Reason During glycolysis, four ATP molecules are produced and net yield is only two ATP molecules.A) extinction of these species from other regions
B) continental separation
C) absence of terrestrial route to these places
D) retrogressive evolution
Correct Answer: B
Solution :
Glycolysis is the oxidation of glucose to pyruvate. One glucose molecule (six carbon atoms) is broken down into two molecules of pyruvate (three carbon atoms). It occurs in cytoplasm. During glycolysis, four ATP molecules are produced and net yield is only two ATP molecules.
