Active transport
Active transport is when a cell membrane protein breaks a high-energy bond (typically ATP into ADP + Pi) in order to move molecule(s) against their concentration gradient. So to directly answer your question. Active transport can be transporting either in or out of the cell depending on whether the molecule being transported is in higher concentration inside the cell or outside.
histone proteins envelope DNA molecules inside the cell.
When sugar molecule crosses the membrane the sugar molecule moves to the outside of the membrane. This is taught in science.
A signaling molecule binds with a membrane protein
These are three different ways that cells have to get things in and out of the cell. Passive transport is movement without the use of energy, active transport requires energy.Active transport requires energy since the molecules are going toward a region that has a higher concentration of that molecule. The cell is 'stuffing' more into itself.Endocytosis means to 'take into the cell'. Usually this a larger molecule and cell must wrap part of itself around the molecule and then can bring it inside. This is a type of phagocytosis (cell eating).This requires energy as well.
Vesicular active transport
Vesicular active transport
It occurs when there are more of that certain molecule on the outside of the cell than the inside. When this is the case, the molecule will automatically pass through the membrane without the cell using energy.

No, only the nob on the outside.
they make the concentration of the solute equal inside and outside of the molecule.
outside of tank.located in front of tank
They help transfer substances from the outside of the cell membrane to the inside.
