During cellular respiration what is produced?
Cellular respiration produces ATP from the breakdown of glucose. ATP, NADH, and FADH2 are produced in Glycolysis. NADH and ATP are produced in the Krebs cycle. And 32 ATP and water are produced in the Electron Transport Chain. The first stage of respiration, glycolysis, occurs in the cytoplasm. The later stages occur in the mitochondria.
What process is cellular respiration?
In cellular respiration, the body cells receive glucose and oxygen molecules from the bloodstream. The oxygen and glucose molecules come together inside the cells to create energy in order for the cells to work, with a leftover of carbon dioxide.
What is the terminal electron acceptor in aerobic cellular respiration?
NAD+ is the first electron acceptor in cellular respiration (O2 is the final acceptor).
Is nitrogen required in the stage of respiration?
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.
Is a product of the first stage of photosynthesis.?
A pair of [free] electrons: {Ever heard of the electron-transport-chain}.
What are the three stages of aerobic respiration?
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.
How does the body breakdown carbohrydrates?
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.

What is the main function of glycolysis?
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?
The breakdown of glucose for energy is called?
Fermentation

Which step of aerobic respiration produces the most ATP?
Aerobic respiration produces the greatest amount of ATP per molecule of glucose oxidized. When a cell uses fatty acid for aerobic respiration it first hydrolyzes fats to glycerol and fatty acids.
What is the terminal electron acceptor in aerobic cellular respiration?
NAD+ is the first electron acceptor in cellular respiration (O2 is the final acceptor).

After the first disruption when electron transfer and ATP synthesize still occur what must be present?
All of the electron transport proteins, as well as ATP, synthase.
What stages of cellular respiration occur in mitochondria?
Glycolysis is the first stage of cellular respiration, but it is in the cytosol that a series of reactions happen and glucose is broken down into 2 pyruvates. When these enter the mitochondrion through active transport (transport proteins), the pyruvate binds with Coenzyme A to become acetyl CoA which then enters the citric acid cycle. So the citric acid cycle, specifically the acetyl CoA attaching to the 4-carbon molecule oxaloacetate is the first stage of cellular respiration that occurs in the mitochondria. Check.
Is the energy from sunlight trapped by chlorophyll located in the electron transport chain?
No, the energy trapped by chlorophyll is located in photosystem I and II. Light energy is first captured by PS II and an electron is then transferred to a primary electron acceptor known as plastoquinone. Pq then transfers it's electron to the cytochrome complex that transfers its energy to the electron transport system which passes it on to plastocyanin which in turn gives its electron to PS I where it is re-excited by photons. This process is known as the electron transport but the energy captured by chlorophyll is located in the photosystems.
