vodka [1.7K]

Answer:

The correct answer will be option-C.

Explanation:

The proton motive force is the force generated by the movement and difference of the charge inside and outside the membrane. The proton motive force is generated due to the electron transport chain as the flow of electron causes the movement of hydrogen ions from the matrix to the inter-membrane space.  

This leads to the increase of H⁺ ion concentration in inter-membrane space and lowering of the H⁺ ions in the matrix. This difference in the charges causes the generation of force called proton motive force which helps the synthesis of ATP.

Thus, Option-C is the correct answer.

Explain how the electron transport chain makes ATP.
zloy xaker [14]

Answer:

t

Explanation:

While Glycolysis and the Citric Acid Cycle make the necessary precursors, the electron transport chain is where a majority of the ATP is created. The Electron Transport Chain makes energy ... At the end of the chain the electrons are taken up by oxygen molecules to make water. This is why oxygen is known as the final electron acceptor.

The images represent sexual and asexual reproduction. These methods of reproduction vary in terms of the genetic
sattari [20]

Asexual reproduction

Sexual reproduction

Explanation:

In asexual reproduction the offspring are genetically identical to the parents.  Asexual reproduction include binary fission, fragmentation and vegetative propagation.

It involves direct inheritance of the genetic copy of the parent without any alteration. The parent gives rise to the offspring without any intermediary process.

In binary fission, the parent simply divides into two to form a new ones.

For sexual reproduction, there is fusion of gametes which carries genetic materials contributed by both parents. The offspring is an offshoot of the genetic combination of the traits of two parents.

Therefore, genetically, offspring produced by sexual reproduction have a distinct copy of the genotypes they posses. They are different from those of the parents.
