How many moles of ATP are produced from each mole of NADH and FAD in the ETS?
Approximately 2.5 moles of ATP are produced from each mole of NADH oxidized in the electron transport chain (ETC), while about 1.5 moles of ATP are produced from each mole of FADH2 oxidized in the ETC. This difference arises from the different redox potentials and positions of NADH and FADH2 in the electron transport chain.
. What happens to the products of the Krebs cycle?
most become reactants in the electron transport chain
What are the reactants and products of anaerobic respiration?

What is the energy of the electrons passing along the etc used to make?
ATP molecules
What occurs in the ETC during cellular respiration?
The high energy from the electron carriers NADH and FADH2 is passed to membrane-bound enzymes that use the energy to pump protons across the inner membrane into the inter-membrane space. The energy is gradually used by an entire "chain" of enzymes to establish a proton gradient across the inner membrane of the mitochondrion. This is where chemiosmosis takes place. Proton motive force generates ATP through the passive diffusion of protons through the enzyme ATP synthase, thus converting ADP and and inorganic phosphate group into high energy ATP molecules. These ATP molecules can drive other endergonic reactions in the cell.
What does FADH2 do in ETC?
FADH2 is an electron carrier similar to NADH, but only the second protein in the ETC accepts FADH2 electrons. So FADH2 is used in the ETC, but it produces less ATP due to it only entering the second protein in the ETC.
How many ATP are created in the ETC?
Approximately 34 molecules of ATP are produced during oxidative phosphorylation in the electron transport chain. Each NADH molecule yields about 3 ATP, while each FADH2 molecule yields about 2 ATP.
How many proton pumps in FADH2?
Just 1 -- Complex I. Complexes IIA and IIB are "powered" by the redox reactions of L-3-P and succinate

Why does fadh2 produce fewer ATP molecules than nadh?
NADH produces 3 ATPs because it donates the proton at a "higher" location in the electron transport chain than does FADH2, which is why FADH2 produce only 2 ATPs. NADH and FADH2 donates electrons and protons into the electron transport chain.

How is food used by the body?
Food is broken down to the molecular level, so its nutrients can be distributed through the blood stream, and so glucose in the food can be converted to glycogen for storage purposes. To get energy from the food, glucose undergoes a process called cellular respiration, where glucose is broken down in glycolysis to release ATP, NADH, and FADH2. ATP is energy that is ready to be used. NADH and FADH2 go through the Krebs cycle, where some of the energy the carry is converted into ATP. The remaining NADH and FADH2 are transported to the Electron Transport Chain (ETC). In the ETC, oxygen that is inhaled accepts the electrons that they carry and they are converted into ATP. There is still a large amount of energy that is unused, and this energy is released as heat and light to keep your body temperature stable.
During which of the following processes is no ATP produced a glycolysis b Krebs cycle c ets d ATP is made during each of the processes above e ATP is not made during any of the processes?
e) ATP is not made during any of the processes. ATP is produced in both glycolysis (2 ATP) and the electron transport chain (ETC) in cellular respiration. The Krebs cycle (citric acid cycle) produces some ATP indirectly through the generation of NADH and FADH2, which then feed into the ETC for ATP production.
What is the energy of the electrons passing along the etc used to make?
ATP molecules
How many ATP molecules in the ETC?

What electron carriers are produced in the Krebs cycle?
There are two electron carriers produced in the citric acid (Krebs Cycle). The first is NAD+ or NADH in its reduced form. The other is FAD+ which becomes FADH2 after being reduced. One turn of the citric acid cycle produces 1 and 3 molecules of FADH2 and NADH respectively.
