How does and electron transport chain result in the gradual release of energy stored in glucose?

Basically NADH and FADH are oxidized to by oxidizing agents in the ETC. Since the electrons are moving from something less electronegative to something more electronegative, free energy in released. This free energy takes H protons and moves it against the inner membrane to the outside. Eventually, the outside will create a concentration gradient, and cause the H protons to pass through a area on the membrane called ATPase. As the H protons move through ATPase, ADP is turned into ATP. This processes doesn't happen all at once, but happens over time from the NADH and FADH glucose creates during glycolosis and the citric cycle. These NADH and FADH are oxidized "slowly", so energy is gradually released to create ATP.

What is required to start and what is produced by the hydrogen and electron transport system?
The proteins involved in the chain, complete with ATP synthase in the end for oxidative phosphorylation, some electron carriers like NADH and FADH2, and the final electron acceptors such as O2.
Can cellular respiration and fermentation be used to release energy?
No. Either cellular repsiration or fermentation can be used to release energy depending on the presence or absense of oxygen. When oxygen is present, it acts as the terminal electron acceptor in cellular repritation, followed by the release of energy When there is no oxygen present, other organic molecules (like lactic acid) accept the terninal electron and energy is generated
What must happen for ATP to release energy to the cell?
glycolysis, krebs, electron transport chain, alcoholic fermentation, and lactic acid fermentation
Does each step of respiration yield ATP?
Yes, glycolysis, citric acid cycle, and electron transport chain each release certain amount of ATP.
How do Cells perform cellular respiration?
Cellular respiration allows organisms to use (release) energy stored in the chemical bonds of glucose (C6H12O6). The energy in glucose is used to produce ATP. Cells use ATP to supply their energy needs. Cellular respiration is therefore a process in which the energy in glucose is transferred to ATP.In respiration, glucose is oxidized and thus releases energy. Oxygen is reduced to form water.The carbon atoms of the sugar molecule are released as carbon dioxide (CO2).The complete breakdown of glucose to carbon dioxide and water requires two major steps: 1) glycolysis and 2) aerobic respiration. Glycolysis produces two ATP. Thirty-four more ATP are produced by aerobic pathways if oxygen is present.In the absence of oxygen, fermentation reactions produce alcohol or lactic acid but no additional ATP.

That's what i'm trying to find out, too :(
What is the release of energy from glucose?
It is broken down into pyruvate to produce 4ATP in glycolysis. It is further broken down in the Kreb's cycle and electron transport chain to produce about 36-38 ATP.
During what does most energy release in the mitochondria?
Electron transport chain

What cellular responses can be altered by food intake?
A. Protein synthesis B. Insulin release C. Glucose uptake D. Nutrient transport E. All of the above E. All of the above Things like insulin release, glucose uptake, blood glucose, glucagon release, satiety hormones, enzyme release, nutrient transport, protein synthesis, excretion, and elimination are just a few of the cellular responses altered by food intake.

What is a series of biochemical reactions that release carbon dioxide and result in fermation of ATP?
I think you are looking for either "the citric acid cycle" or "the electron transport chain"
Does each step of respiration yield ATP?
Yes, glycolysis, citric acid cycle, and electron transport chain each release certain amount of ATP.
When cells use oxygen to release energy from sugar whT do they produce?
This is a very general question, but I'll give it an attempt. Glucose is oxidized via glycolysis to produce reduced coenzymes (2 NADH) and ATP. The product of glycolysis (pyruvate) then enters the citric acid cycle and is further oxidized to produce more reduced coenzymes (3 NADH and 1FADH2) and GTP (a high energy phosphate equivalent to ATP). The reduced coenzymes (NADH, FADH2) enter the electron transport chain and then are oxidized to release electrons. The electrons traverse the electron transport chain via several electron transport molecules and ultimately reduce oxygen to form metabolic water.
What process do mitochondria use to release energy from glucose using oxygen?
The mitochondria is not responsible for the breakdown of glucose, but this actually occurs starting in the cytoplasm via glycolosis. Glycolosis breaks down glucose to pyruvate, which enters the mitochondria and is broken down to Carbon dioxide via the Citric Acid Cycle (a.k.a. the Kreb cycle). The reduced agents produced from here donate their electrons to the electron transport chain, with the final electron acceptor being Oxygen. The electron transport chain pump hydrogen atoms from the inner matrix to the outer region in the mitochondria as these electrons move down the chain. This hydrogen gradient is used to create ATP much like a dam creates electricity from water. Sources differ on how many ATP are created per molecule, but on average it is 2.5 moles of ATP per mole of NADH, and 1.5 moles of ATP per mole of FADH2.
What process breaks down glucose before cellular respiration?
Glucose is broken down IN cellular respiration, also called the Kreb cycle. Glucose enters this electron transport chain process intact, and is broken down to CO2 and water, while giving off chemical energy which is stored in the form of ATP molecules for the cell to use for chemical energy in metabolic processes. Glucose is not broken down before cellular respiration; it is broken down IN the process.
