The first stage is Glycolsis, which works anaerobicly and occurs in the Sarcoplasm (the cytoplasm of a muscle). This process happens happens in 10 stages where various, slight but important changes are made. In this process 4 ATP molecules are produced but 2 are used in the breakdown of glucose leaving a net gain of 2. Glucose is split to from 2 3-carbon sugars, which is then oxidised to form Pyruvate. At this point aerobic respiration meets anerobic respiration. The pyruvic acid is oxidised forming Acetyl Co A, a 2 carbon compound that can enter the kreb cycle. In this cycle Acetyl Co A combines with Oxaloacetic acid to form citric acid, a 6 carbon compound. This releases carbon dioxide which can be safely breathed out, it resynthesises a further 2 ATP and releases hydrogen which is taken by NAD to the electron transfer chain in the Mitochchondria. The electron transfer chain occurs in the Cristae of the Mitochondria (where the enzymes and proteins for this chain are attached to the inner wall). NAD and FAD combine with the hydrogen ions made during glycolsis to make NADH and FADH. They then donate electrons to the first carrier molecule of the electron transfer chain. The electrons pass through the chain by a series of redox (reduction and oxidation) reactions. The energy from the electrons and the hydrogen powers ATPsynthase which uses ADP and phosphate to resynthesise ATP. At the end of this chain electrons combine with protons and Oxygen to form water.
The molecule that serves as the common branch point for either the anaerobic or aerobic pathway is pyruvate. Depending on the availability of oxygen, pyruvate can either be converted into acetyl-CoA to enter the aerobic pathway (Krebs cycle or citric acid cycle) or undergo fermentation in the absence of oxygen.
Oxygen
During exercise, the body primarily uses two pathways to release energy: the aerobic pathway, which requires oxygen and is more sustainable for longer durations of exercise, and the anaerobic pathway, which does not require oxygen and is used for short bursts of intense activity. Each pathway produces energy in the form of adenosine triphosphate (ATP) to fuel muscle contractions.
The two pathways that follow glycolysis are aerobic and anaerobic.

Aerobic Energy Pathway
The aerobic pathway produces more energy than the anaerobic pathway. Aerobic respiration generates a much higher yield of ATP molecules from glucose compared to anaerobic fermentation. Anaerobic metabolism is a less efficient process that produces ATP without the use of oxygen.
no, it is anaerobic metabolism. (without oxygen, rather than with oxygen.)
The Krebs cycle is an example of an aerobic metabolic pathway, as it requires oxygen to function efficiently.

Glycolysis is the metabolic pathway common to both aerobic and anaerobic processes of sugar breakdown. It is the metabolic pathway that converts glucose into pyruvate. All organisms produce a high energy compound ATP by releasing energy stored in glucose and other sugars.
