Glycolysis
Glycolysis is the metabolic pathway that converts glucose into pyruvate. It is the first step in cellular respiration and occurs in the cytoplasm of the cell. Let's analyze each statement and determine which one is incorrect.
a) It occurs outside mitochondria
This statement is correct. Glycolysis takes place in the cytoplasm of the cell, outside the mitochondria. This is in contrast to the later stages of cellular respiration, such as the citric acid cycle and oxidative phosphorylation, which occur inside the mitochondria.
b) It is an anaerobic phase
This statement is correct. Glycolysis can occur in the absence of oxygen and is therefore considered an anaerobic process. It is the only step in cellular respiration that does not require oxygen.
c) Glucose undergoes partial oxidation to form 2 molecules of pyruvic acid
This statement is correct. During glycolysis, glucose is broken down into two molecules of pyruvic acid (also known as pyruvate). This process involves a series of enzymatic reactions that result in the partial oxidation of glucose.
d) Glucose is phosphorylated to glucose-6-phosphate by isomerase enzyme
This statement is incorrect. Glucose is phosphorylated to glucose-6-phosphate, but not by an isomerase enzyme. The correct enzyme involved in this step is hexokinase. Hexokinase catalyzes the transfer of a phosphate group from ATP to glucose, forming glucose-6-phosphate.
So, the incorrect statement is option 'D'. Glucose is phosphorylated to glucose-6-phosphate by hexokinase, not by an isomerase enzyme.
