Question

At the end of glycolysis, ---- --- -- molecules are obtained. Fill in the blank and explain the statement

Answer 1

At the end of glycolysis, pyruvate molecules are obtained.

Glucose + 2 Pi + 2 ADP + 2 NAD+ → 2 Pyruvate + 2 ATP + 2 NADH + 2 H+ + 2 H2O

2 pyruvate molecules are formed in the oxidation reaction. Oxidation reaction takes place via dehydrogenation and the product formed is NADH.

Amount of NADH produced is equal to the amount of pyruvate produced. In anaerobic conditions, lactates are formed. The final products are 2NADH, 2ATP, and 2 pyruvates.

Answer 2

At the end of glycolysis, pyruvic acid, ATP, NADH and water molecules are obtained

Explanation:

• At the end of glycolysis, pyruvate ,ATP,NADH2 and water molecules are obtained.

$Glucose + 2 Pi + 2 ADP + 2 NAD+ ------ 2 Pyruvate + 2 ATP + 2 NADH + 2 H+ + 2 H2O$

• By the oxidation reaction 2 pyruvate molecules are formed.

• The Oxidation reaction takes place via dehydrogenation and the product formed is NADH.

• NADH produced in the reaction is equal to the amount of pyruvate produced.
• Under anaerobic conditions, lactates are formed.
• The final products are 2NADH, 2ATP, and 2 pyruvates.
