What components of the cell membrane allow for the movement of some small an medium molecules? Why is energy not required in this movement? Que componentes de la membrana celular permiten el movimiento de algunas moléculas pequeñas y medianas? Por que no se requiere energía en este movimiento?

acceleration= v2-v1/t so 8m/s-3m/s / 3s =to 8/3 or

2.67 m/s^2

hope i
