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.
Carbon and fluorine combine covalently to form a binary compound. the formula of the compound with the name carbon tetrafluoride is CF4.
Serial Monogamy is the behavior n mating in which one male breeds with a female for a certain period of time and then finds a different mate the following mating season. It is defined as a succession of short monogamous relationships or <span>the practice of having a number of long-term romantic or sexual partners in succession.</span>
Answer:
Because water exhibits cohesive behavior.
Explanation:
Cohesive behavior can be explained as a behavior where molecules are attracted to each other.
And this means that, water molecules are attracted to each other because of their cohesive behavior. This makes them to be attracted to other substances, such as the walls of the xylem of plants.
In this case, it is believed that the water molecules behave this way because they are polar, that is, there is an electronegativity difference between the bonded atoms. And this enables it to move from the roots to the leaves of the plants.
Just like humans and other animals, pathogenic bacterias also has the capability to evolve.
These pathogens usually come to life as soon as they enter a host. When you use antibiotics, the majority of them will die, but several of them could survive.
When these survivals replicate, it will creates more bacterias that has higher immune towards antibiotics compared to normal bacteria
