Which statement is true of both active transport and facilitated diffusion? question 4 options: both occur in only one direction. both involve proteins in the cell membrane. both require atp. both move materials down a concentration gradient.

The correct option is this: BOTH MOVE MATERIALS DOWN A CONCENTRATION GRADIENT.
Active transport is a type of transport in the living cells in which energy is needed to move materials across a semi permeable membrane against a concentration gradient. Passive transport on the other hand is a type of transportation in cells, in which energy is not needed to move the materials across a biological membrane but the movement of the materials is against a concentration gradient.

True to the fact it is actually false
