The electron transport chain consists of protein complexes embedded in the inner mitochondrial membrane, where it generates a proton gradient by a series of oxidation‑reduction, or redox, reactions. Although all of the stages of cellular respiration (glycolysis, the citric acid cycle, and the electron transport chain) are necessary for life, the electron transport chain is sometimes called the most important stage.First complete the sentence, then answer the question.

The question is incomplete as it does not have the option which are provided in the attachment

It is potential energy that can power ATP synthesis

Explanation:

Electron transport chain is considered the most important stage of the cellular respiration as it is the only stage during which a high amount of ATP is produced.

The electron transport through various protein complex where electrons lose its energy and are used to drive the outflow of the proton to the outside of the mitochondrial membrane.

When protons accumulate outside the membrane creates a proton gradient as a result of which the proton needs to enter the cell. The protons enter through the ATP synthase where the potential energy of the proton is used to rotate the rotor and thus ATP is formed from the ADP.

Thus, the selected option is correct.

Gene Linkage

Explanation:

In a situation where we have two genes which are for two different traits or different characteristics situated on the same chromosome they will said to be LINKED GENE and will often have the same Gene inheritance which is what is called GENE LINKAGE reason been that the genes are on one chromosome and Secondly they are situated very close to one another which is why they will mostly be inherited together. Example a person may have a brown eyes and a brown hair because the genes for the hair and eyes are situated close to one another which is why the genes are both inherited together.
