The electron transport chain is important for the production of the ATP molecule. The oxygen molecule acts as the final electron acceptor in the electron transport chain.

The size of the cation is always small as compared with the parental atoms. Two electrons are removed from Fe2+ and three electrons are removed from Fe3+. This removal of electron increases the attraction force between the electron of the outermost shell and the nucleus and decreases the repulsion force between the electrons and thus decreases in size.

Label the plasma membrane of a cell that is placed in a solution with concentrations of calcium ion and lactose that are greater

Serjik [45]

Answer:

Observe the graphic for the answer

Explanation:

1.- The first channel from left to right is the pump that exports protons, as you can observe, there are plenty of protons in the outside part, so the cell need to balance the quantity, that is the reason to be of a pump.

2.- The channel in the middle is the responsible for moving calcium, the same as the protons, from the outside part to the inside of the cell.

3.- The lactose carrier, that is the last channel, since the lactose is a carbohydrate that is quite big, needs a protein as a carrier to move it from the outside part to the inside, actually, some carriers can modify it shape as we can observe in the drawing to get inside some substances.

Hope this info is useful.
