Which of the following cellular metabolic processes can occur both in the presence or absence of O 2 ?

Step-by-step solution

Glycolysis is a catabolic process where the substrate glucose is broken down into smaller molecules- pyruvic acid and occurs anaerobically. The site for glycolysis is the cytoplasm. It is a stepwise process involving a series of ten enzymes to catalyze the processes. In it, some of the intermediates may get involved in other metabolic processes than respiration. Like DHAP formed can be used in the lipid synthesis as it is a source of glycerol to join fatty acids. It is the connecting link or common pathway between
