Describe the relationship between electron (e-) transport chain, H+ gradient and ATP synthesis!
Homework Answers
The metabolic pathway through which the electron passes from one
carrier to another,is called the electron transport chain and it is
present in the inner mitochondrial membrane. With the help of lots
of reaction including electrons the H+ gradient is made in inter
membrane space. For each
ATP produced, 2H+ passes through F0
from the intermembrane space to the matrix down the electrochemical
proton gradient.

Which of the following best describes what occurs during the electron transport chain? The diffusion of H+s provides the energy needed to make electrons move through the electron transport chain. Once the electrons reach oxygen, ATP is produced. O An H+ gradient is used to place oxygen at the end of the electron transport chain. The oxygen then pulls electrons towards it, which results in the synthesis of ATP. The energy of moving electrons is used to generate a proton...

In mitochondria, a proton gradient is established by the movement of electrons through the electron transport chain. Protons are moved to the intermembrane space against the concentration gradient and the flow back to the matrix via facilitated diffusion using the ATP synthase. Describe how this proton flow contributes to ATP synthesis and the role played by aspartic acid in this process.
