The subatomic particles which determine an element's chemical properties are electrons. Electrons are present in the specific orbitals in an atom. Thus, the correct option is B.

What is an electron?

An electron is a negatively charged subatomic particle. An electron can be either bound to an atom or in free state. An electron which is bound to an atom in an orbital is one of the three types of particles present within the atom. Other primary subatomic particles which are present in an atom include protons and neutrons. Together, electrons, protons and neutrons form the nucleus of an atom.

Electrons were discovered by J.J. Thomson in 1897. The mass of an electron is 9.109×10⁻³¹ kilograms and the charge is −1.602176634×10⁻¹⁹ C.

Therefore, the correct option is B.

Answers

Answer:

No After your cell dies of another one come. Your cells are still the same

Explanation:

When you age, cells do divide and reproduce more cells. However when you age the reproduction process of cells gets slower and they can die off before they can reproduce. There can be many problems with your cells that can make cell count lower such as Atrophy, and Dysplasia. When you age, cells are a contributing factor of making you age. They can change your skin, face, etc.. So the answer would be no, you would not have more than you did when you were five.

Where does the H+ come from that makes ATP synthase work?

Answers

Answer:

Electron Transport Chain

Explanation:

Gizmos Cell Respiration

The H+ that's vital in making ATP synthase work comes from the electron transport chain.

The electron transport chain can be found in the mitochondria. It is a series of protein complexes that are able to transfer electrons from the electron donors to the electron acceptors.

It should be noted that the transfer of the electrons from the electron donors to the electron acceptors is done through the redox reactions. This is illustrated in the H+ that made the ATP synthase work.
