Answer:option A
The force driving simple diffusion is concentration gradient and the energy source for active transport is ATP.
Explanation:
Diffusion is the movement of substances from a region of high concentration to a region of low concentration in a lipid bilayer without any intermediary assistance. The driving force for simple diffusion is the concentration gradient and the energy source for active transport is Adenosine triphosphate (ATP).
Concentration gradient is when a solute is more concentrated in one area than another solute.
Answer:
A) the concentration gradient; ATP
The force driving simple diffusion is the Concentration gradient while the energy source for active transport is ATP.
Diffusion involves the movement of particles from a region of higher concentration to a region of lower concentration. Diffusion occurs as a result of the difference in the type, shape, size and amount of particles contained in the solutes. This forms a gradient known as the concentration gradient which acts as the driving force in the movement of the particles to create an equilibrium.
The energy source for active transport is ATP( Adenosine Triphosphate) .Active transport mainly occurs in cells via the cell's energy called the ATP.The ATP helps to move cell molecules against a gradient thereby ensuring that there is equilibrium in concentration within cells to prevent harm or death to cells.
