a) What is glycolysis?
b) Where does glycolysis occur?
c) Glycolysis is a partial oxidation. Justify
d) Calculate the number of ATP molecules synthesized in glycolysis by the partial oxidation of one molecule of glucose
Answers
Answer:
a) ans - the breakdown of glucose by enzymes, releasing energy and pyruvic acid.
b) ans - Glycolysis takes place in the cytoplasm. Within the mitochondrion, the citric acid cycle occurs in the mitochondrial matrix, and oxidative metabolism occurs at the internal folded mitochondrial membranes (cristae).
c) ans - Glycolysis takes place in the cytoplasm. Glucose undergoes partial oxidation in glycolysis; to form two molecules of pyruvic acid. ... Since two molecules of ATP were utilised during phosphorylation of glucose, hence net production of ATP at the end of glycolysis is two for each molecule of glucose.

Glycolysis is the process in which there is partial oxidation of the glucose molecule carried out. The glucose molecule is broken down to give two molecules of pyruvate. There are 4 ATPs produced but 2 are used up, so the net yield of glycolysis is 2 ATP.
