Which mechanism requires energy?

a) diffusion of oxygen into red blood cell

b) diffusion of ions through a potassium channel

c) osmosis

d) exocytosis

d is the correct answer because Exocytosis is a type of vesicle transport which cells use to move substances out of their interior. It is an active process because it requires the energy of ATP to occur. ATP occurs when the last phosphate breaks tahts how energy flows through

the most common energy conversion is from kinetic energy to potential energy, and then from potential energy to kinetic energy.

later on comes the heat energy, mechanical energy, and other energy conversions.

this energy conversion is so common that we can find it in our day to day lives as well.

- one of the most common energy conversions involves the changing of potential energy to kinetic energy or kinetic energy to potential energy
