Answer:
Three proteins directly contribute to the proton gradient by moving protons across the membrane
Explanation:
The Electron transport chain is a group of proteins and molecules incrusted in the internal mitochondrial membrane and organized into four complexes, I, II, III, and IV. These complexes contain the electron transporters and the enzymes necessary to catalyze the electron transference from one complex to the other. Complex I contains the flavine mononucleotide -FMN- that receives electrons from the NADH. The coenzyme Q, located in the lipidic interior of the membrane, conducts electrons from complex I and II to complex III. The complex III contains cytochrome b, from where electrons go to cytochrome c, which is a peripheric membrane protein. Electrons travel from cytochrome c to cytochromes a and a3, located in the complex IV. Finally, they go back to the matrix, where they combine to H+ ions and oxygen, to form the water molecule. As electrons are transported through the chain, protons are bombed through three proteinic complexes from the matrix to the intermembrane space. These are complexes I, III and IV.
Option C. the larger A pairs with the smaller T, and the larger G pairs with the smaller C.
Answer:
D
the skeletal system provides protection for the brain and spinal cord
Using little tweezers you can pull each strand
Attribution theory refers to how the social perceiver uses information in trying to explain casual events in everyday life. This primarily discusses as to how the information gathered are combined with in order to create a casual judgment. According to Heide (1958), people are like naive psychologists who are trying to figure out how and why things happen. For example, if someone with a bad family background succeeds, people will say that he used his struggle as a motivation and if he fails people will say that he succumb to the challenges.
