Answer 2

The process of complete oxidation of glucose consists of:

2. Glycolysis, Krebs Cycle, and Terminal Oxidation

Here's a brief explanation of each step:

1. Glycolysis: This is the initial step in glucose metabolism, where one molecule of glucose is broken down into two molecules of pyruvate in the cytoplasm of the cell. Glycolysis does not fully oxidize glucose but is the first step in its breakdown.

2. Krebs Cycle (Citric Acid Cycle): After glycolysis, the pyruvate molecules generated enter the mitochondria and are further oxidized in the Krebs cycle. During this cycle, carbon atoms are released as carbon dioxide, and high-energy electrons are transferred to carrier molecules.

3. Terminal Oxidation (Electron Transport Chain and Oxidative Phosphorylation): The high-energy electrons produced in the Krebs cycle are transferred to the electron transport chain (ETC) located in the inner mitochondrial membrane. In the ETC, electrons are passed through a series of protein complexes, releasing energy in the process. This energy is used to pump protons (H+ ions) across the mitochondrial membrane, creating a proton gradient. The flow of protons back into the mitochondrial matrix through ATP synthase drives the synthesis of ATP (oxidative phosphorylation). Oxygen serves as the terminal electron acceptor in this process, ultimately forming water when it accepts electrons and protons.

So, option 2 (glycolysis, Krebs cycle, and terminal oxidation) is the correct choice for the complete oxidation of glucose.
