Answer: The ATP are formed by two way when one molecule of glucose is oxidized
1) 10% ATP formed through substrate level phosphorylation by directly ADP to ATP transfer of phosphate.
2) 90% ATP formed through oxidative phosphorylation by ATP synthase via proton gradient. These energy conserved in the form of chemical bond as NADH and FADH2.
The one NADH produced 3 ATP and one FADH2 produced 2ATP through proton gradient in electron transport chain (ETC).
In ETC, NADH and FADH2 indirectly electron transfer to O2 molecule and formed H2 O. These electron first accepted coenzyme Q and Q electron transfer to cytochrome C and finally electron accepted by O2 molecule and combined with it and formed water molecule. The proton transfer to ATP synthase and formed ATP. These above process completed in inner membrane of mitochondria through electron transport system. These above process is called chemiosmosis.
ATP synthase consist of two sub domain that is F0 membrane bound complex and F1 complex composed of catalytic head and stalk.

High-energy electrons from molecules of NADH and FADH2 are transferred to a chain of proteins within the electron transport chain. What is the final protein in the electron transport chain? O cytochromec oxygen O carbon dioxide NAD+ ubiquinone
Which electron carrier brings electrons to the electron transport chain via complex II? Which electron carrier brings electrons to the electron transport chain via Complex II? FADH_2 FAD NADH NAD^+ Which electron carrier brings electrons to the electron transport chain via Complex I? FADH_2 FAD NADH NAD^+ As the electron transport chain proceeds, electrons H^+ ions water CO_2 molecules are pumped into the intermembrane space cytoplasm matrix nucleus
Fill in the blanks regarding the electron transport chain and oxidative phosphorylation. Complex1 accepts electrons from NADH and uses coenzyme Q to transport them to complex 3. Complex 2 accepts electrons from FADH2 and uses coenzyme q to transport them from complex 3 to complex 4. The ATP synthase will transport 3H+ ions for every 2 ATP produces. This entire process occurs across the inner mitochondrial membrane. Fill in the blanks regarding the electron transport chain and oxidative phosphorylation

Cellular respiration: The Electron Transport Chain The breakdown of glucose ends during the Krebs cydle; however, it is important to note that the energy previously contained in glucose is mostly stored in NADH and FADHz. In the last step of celular respiration, the high-energy electrons within NADH and FADH2 are passed within a set of proteins found in the inner membrane of the mitochondrion, collectively known as the electron transport chain. The electrons provide the energy to create ATP, which...
Which of the following could explain why transfer of electrons from FADH2 to Coenzyme Q (CoQ) is not coupled to proton transfer, but transfer from NADH to Coenzyme Q is? Select one: a. FADH2 donates more electrons than NADH to the electron transport chain. b. Because FADH2 has higher affinity for electrons than Coenzyme Q c. Because FADH2 is a higher energy carrier than NADH d. Because the transfer of electrons from FADH2 to CoQ does not release enough energy....
