Which of the following are part of the chemiosmotic coupling model? Protons are pumped out of the mitochondrial matrix into the
Lina20 [59]

The correct answer is: Protons are pumped out of the mitochondrial matrix into the intermembrane space

Chemiosmosis can be described as movement of ions across a selectively permeable membrane, down their electrochemical gradient. It occurs during the cellular respiration within mitochondria and it is involved in ATP synthesis (oxidative phosphorylation via ATP synthase).

Electrons from electron carriers (NADH and FADH) donate electrons to the electron transport chain and that causes changes in protein complexes of electron transport chain. As a consequence, protein complexes pump H+ across a selectively permeable cell membrane from the mitochondrial matrix into the intermembrane space of mitochondria.  

H+ can only get back and pass through the inner mitochondrial membrane with the help of ATP synthase (down their electrochemical gradient). ATP synthase turned by the force of the H+ diffusing through it forms ATP by adding a phosphate to ADP.

How is the simulation different from the real world? Explain in 3 or more sentences.
Aleks [24]
Simulations generally involve a simple design. In contrast, the world is a very complex system. Many events, such as how we farm, can disrupt the world's delicate balance. Simulations do not take into account the varied interactions that affect events in the real world.
