Active transport is moving substance against its gradient so it requires an input of energy to achieve this. One example is Na K ATPase. This is a secondary active transporter that pumps 3x Na out of the cell for 2x K into the cell. There are so much more Na outside the cell and already a lot of K inside the cell so to push the molecules there is an expenditure of ATP to do this.

Active transport uses cellular energy, unlike passive transport, which does not use cellular energy. Active transport is a good example of a process for which cells require energy.

Where are protons and electrons that are responsible for the chemical properties of an atom are located?
The answer is "the electron." "Valance Electron" is a more specific and correct answer.
What particles play the most active role in chemical bonding?
I think it's electrons.
How many electrons can a NADH molecule carry?
The electron transport chain is also known as the respiratory chain. NADH carries electrons in the form of hydrogen atoms to the electron transport chain.
What role do valence electrons play in the formation of bonds-?
The valence electron are involved in the sharing of electrons with the other atoms to form ionic bonds.
What role play oxidising agent in a reaction?
They oxidize the other substances by accepting electrons and are therefor reduced.
What is the role of electron emitter?
emitting electrons
What is the role of electrons in a voltaic cell?
a volcanic cell has electrodes and electrons flow through electrodes .
The subatomic particles that play the greatest role in bonding are?
Electrons.
What role do electrons play on determining the stability of an atom?
The role electrons play in stabilizing an atom is they balance out the charge of the protons. If an element has more protons than electrons, it has a positive, not neutral, charge, and vice versa. Unpaired electrons can cause an element to be chemically reactive and/or radioactive. Hope this helps!
When NADH passes its electrons to the ETC it is?
NAD+
What particles plays a role in creating bonds is it neutron electron proton?
Electrons (that too the valence electrons or electrons in the outermost shell / orbital) are involced in bond formation.
What is the role of water in cyclic photo phosphorylation?
It provides electrons and protons.
What is lone pairs of electrons?
Lone pair of electrons are highly unstable and highly reactive and plays major role in the chemical bonding.
What has role in neutrons changing into protons and electrons into unstable atoms?
strong force
What features of the carbon atom adapt so elegantly to its central role in the structure of bilogical molecules?
Carbon has four valence electrons and can readily accept, donate or share the four electrons to be stable and this feature plays a great role.
What role do valance electrons playing the formation of compounds and elements?
The valence electrons are the only electrons involved in chemical bonding. In covalent bonding sharing occurs In ionic bonding electrons are tranferrred In metallic bonding they are deloclaised across the lattice
What is water is the role in the light reaction of photosynthesis?
It provides the electrons. Process is called Photolysis
