No it is actually the final step in the breakdown of glucose
The amount of energy produced in the partial breakdown of glucose is 2 molecules of ATP. This occurs during the process of glycolysis, which is the first stage of cellular respiration. Additional energy is later produced through the complete breakdown of glucose in the citric acid cycle and the electron transport chain.
Glycolysis is the first step in cellular respiration that breaks down glucose into pyruvate, generating some ATP. The Krebs cycle (or citric acid cycle) then further breaks down pyruvate to produce more ATP. Finally, oxidative phosphorylation in the mitochondria produces the most ATP through the electron transport chain.
NAD+ is the first electron acceptor in cellular respiration (O2 is the final acceptor).
Yes, oxygen is the fuel for respiration... oxygen + glucose = carbod dioxide + water + Energy However, the carbon dioxide and oxygen for a plant or tree would be the other way round because plants breath in co2 and give out oxygen.

The first stage is the break down of glucose. The second stage is the Krebs Cycle which breaks down the pyruvic acid. The third stage is the electron transport system which occurs in O2 and in the mitochondria.
Carbohydrates such as glucose for example are catabolized(break down) by certain metabolic pathways. Glycolysis pathway is the first step where glucose is converted to pyruvate. Subsequently, pyruvate undergo Kreb's cycle and electron transport chain to synthesis energy or ATP molecules. Disaccharide (sucrose as example) or Polysaccharides such as Glycogen are first converted to its monomeric forms such as glucose, fructose, galactose etc. before entering the above said pathways.

Finally, oxidative phosphorylation in the mitochondria produces the most ATP through the electron transport chain.
Oxygen and glucose are needed for respiration to take place. Oxygen is used as the final electron acceptor in the electron transport chain in aerobic respiration, while glucose is broken down to release energy in the form of ATP.
There is no electron transport chain in glycolysis as the chain is in the inner lumen of the mitochondria and glycolysis takes place in the cytosol. I suggest you get your question straightened out and resubmit it. Electron carriers do go from the glycolyitic process to the electron transport chain, FADH and NAD both pick up electrons ( they are reduced ) from the oxidation of glucose. Not very many though, as they get most of the electrons in the Krebs cycle. Is this what you meant?
In order for electron transfer and ATP synthesis to continue after the first disruption, an intact electron transport chain and a functioning ATP synthase enzyme must be present. The electron transport chain allows for the movement of electrons, while ATP synthase uses the energy generated from this flow of electrons to produce ATP.
NAD+ is the first electron acceptor in cellular respiration (O2 is the final acceptor).
Well first you need to go through an easy process, called cellular respiration. the three phases areglycolysis, Krebs cycle and the electron transport chain. but to start glycolysis, you must first "invest" 2 ATP. by the end of cellular respiration you end up with a NET GAIN of 32 ATP, while 34 is produced.
I think that it is Mitochondria...but im not sure. The first stages in the breakdown of glucose occur in the cytoplasm of the cell. These reactions do not use oxygen and only a small amount of energy is converted to ATP. Much more energy is released in the second stage which does take place in the mitochondria. This is the stage which uses oxygen.
