Biology Question on respiration in plants
At the end of glycolysis, six carbon compound ultimately changes into
A
ethyl alcohol
B
acetyl Co-A
C
pyruvic acid
D
ATP.
Answer
pyruvic acid
Explanation
Solution
Glycolysis or EMP pathway is the breakdown of glucose to two molecules of pyruvic acid through a series of enzyme mediated reaction releasing energy. Pyruvic acid is a 3-carbon compound. In glycolysis net gain of 2ATP and 2 NADH2 molecules occurs. It can be represented in equation form as -
C6H{12}O6+2ADP+2Pi+2NAD-->2CH3COCOOH+2ATP+2NADH2
