Glycolysis, Krebs cycle and the electron transport chain.

Glucose, polysaccharides and discaccharides go into glycolysis and that cycle can produce 2 ATP (adenosine triphosphate).

Electrons are transfered to the Electron Transport chain. Pyruvic acid fermentation can make 2 ATP then goes down, releasing 2 NADH2 to the Electron Transport chain, with Acetyl CoA into the Krebs cycle which makes 4 CO2 and 4 ATP as well as sends 6 NADH2 and 2 FADH2 down to the electron transport chain.

The 2 NADH2, 2 NADH2, 6 NADH2 and 2 FADH2 then go down the electron transport chain realeasing energy a bit each time it goes down and in the end 34 ATP is created.

What element must be present for both steps of cellular respiration to occur?

Oxygen is the element that must be present for both steps of cellular respiration to occur. It acts as the final electron acceptor in the electron transport chain, allowing for the production of ATP through oxidative phosphorylation.


Do all of the steps of cellular respiration need oxygen?

No; and those that do not are called anoxic steps.


Steps of cellular respiration if oxygen is NOT present in the cell?

If oxygen is not present in the cell, the process of cellular respiration cannot proceed normally. In the absence of oxygen, anaerobic respiration occurs. This process involves glycolysis followed by either lactic acid fermentation in animal cells or alcoholic fermentation in yeast and some bacteria to produce ATP.


How are the step of cellular different when it is anaerobic respiration?

The steps of cellular respiration is different when it is anaerobic respiration compared to aerobic respiration. The main difference is because aerobic respiration uses oxygen and anaerobic uses other elements but the other steps are similar.


Which steps in aerobic cellular respiration require oxygen?

The citric acid cycle and the electron transport chain are the steps in aerobic cellular respiration that require oxygen. Oxygen is the final electron acceptor in the electron transport chain, where it helps generate ATP by facilitating the transfer of electrons from NADH and FADH2 to oxygen.


What parts of cellular respiration don't require oxygen?

Glycolysis is the only part of cellular respiration that does not require oxygen. It is the process by which glucose is broken down to produce pyruvate and a small amount of ATP. The subsequent steps of cellular respiration, including the Krebs cycle and electron transport chain, require oxygen to fully extract energy from glucose.


Aerobic respiration is classified as?

Aerobic respiration is classified as a metabolic process in cells that requires oxygen to produce energy in the form of ATP. This process involves the breakdown of glucose molecules through a series of steps that occur in the mitochondria.


What are the reactants in cellular respiration?

The reactants in cellular respiration are glucose and oxygen. Glucose is broken down in a series of steps to produce energy in the form of ATP, while oxygen acts as the final electron acceptor in the electron transport chain to drive ATP synthesis.


What are the starting materials cellular respiration?

The starting materials for cellular respiration are glucose and oxygen. Glucose is broken down in a series of steps to produce ATP, the energy currency of the cell, with oxygen acting as the final electron acceptor in the process.


Which steps of cellular respiration occur in the cytoplasm?

glycolysis


What is a reactant of cellular respiration?

OK the reactants of cellular respiration is obviously C6H12O6 which is glucose and O2. The product of cellular respiration is fairly simple as well, carbon dioxide, water, and ATP. hope that answers your question.


What is required to begin the cellular respiration process?

Cellular respiration requires glucose and oxygen as the initial reactants. Glucose is broken down in a series of steps to produce ATP, the cell's main energy source. This process occurs in the presence of oxygen and involves various enzymes and molecules within the cell.
