Incorrect Statement in Glycolysis
Explanation:
Glycolysis is the metabolic pathway that converts glucose into pyruvate. Let's look at each statement and determine which one is incorrect.
a) Both glucose and fructose are substrates of glycolysis: This statement is correct. Both glucose and fructose are substrates of glycolysis. Glucose is the most common substrate, but fructose can also enter the pathway through the action of the enzyme fructokinase.
b) NADH is utilised during conversion of PGAL into 1, 3 bisphosphoglycerate: This statement is incorrect. NADH is not utilised during this step of glycolysis. In fact, NADH is produced during the conversion of glyceraldehyde 3-phosphate (G3P) into 1,3-bisphosphoglycerate (1,3-BPG).
c) A molecule of water is removed during conversion of 2-phosphoglycerate to phosphoenolpyruvate: This statement is correct. The conversion of 2-phosphoglycerate (2-PGA) to phosphoenolpyruvate (PEP) involves the removal of a molecule of water.
d) Pyruvic acid is the key product of glycolysis: This statement is correct. Pyruvic acid (or pyruvate) is the key product of glycolysis. It is produced from the breakdown of glucose or fructose and can be further metabolised by various pathways, depending on the cellular conditions.
Therefore, the incorrect statement in glycolysis is option B, "NADH is utilised during conversion of PGAL into 1, 3 bisphosphoglycerate".
