Detailed explanation-1: -Answer and Explanation: The process in eukaryotic cells that will proceed normally whether oxygen is present or absent is b. glycolysis. Processes such as chemiosmosis, oxidative phosphorylation, the citric acid cycle, and electron transport will only occur when there is oxygen present.

Detailed explanation-2: -Answer and Explanation: If there is no oxygen available for a eukaryotic cell, only glycolysis will take place. Glycolysis will occur whether oxygen is present or not.

Detailed explanation-3: -Nearly all living organisms carry out glycolysis as part of their metabolism. The process does not use oxygen and is therefore anaerobic (processes that use oxygen are called aerobic). Glycolysis takes place in the cytoplasm of both prokaryotic and eukaryotic cells.

Detailed explanation-4: -Glycolysis produces 2 ATP per glucose molecule, and thus provides a direct means of producing energy in the absence of oxygen. This process of breaking down glucose in the absence of oxygen is aptly named anaerobic glycolysis.[1]

Detailed explanation-5: -Glycolysis is a linear metabolic pathway of enzyme-catalyzed reactions that convert glucose into two molecules of pyruvate in the presence of oxygen or into two molecules of lactate in the absence of oxygen.
