The outcome of this error would be that the gradient of the proton in the thykaloid space would not be able to be used to produce ATP. This is because the ATP synthase was inserted in a backward position to the membrane which would cause for protons to the build up in the thykaloid space.
It is the protein gradient in the thylakoid space that causes the production/generation of ATP molecules. During the process of electron transport, H+ ions are pumped across the thylakoid membrane and a electrochemical proton gradient is attained that drives the synthesis of ATP in the stroma.
Now when atp synthase complexes are reversed, H+ ions are not pumped across the thylakoid membrane which destabilizes the electrochemical proton gradient and lead to halt of production of ATP
A head injury happens due to trauma to the brain or skull and classified as close or sometimes penetrating. It may occur right away or develop slowly. An example is contusion which is the answer on this scenario. This is called mild traumatic injury caused by a blow on the head yet none of the tissue of the brain is torn.
