which type of transport requires energy and would be used to move substances across a cell membrane against their concentration gradient (from low to high concentration)?\no facilitated diffusion\no simple diffusion\no active transport\no osmosis

Answer

Brief Explanations:

Facilitated diffusion and simple diffusion move substances along the concentration gradient (from high to low) without energy input. Osmosis is the diffusion of water across a semi - permeable membrane and also does not require energy to move substances against a concentration gradient. Active transport uses energy (usually ATP) to move substances against their concentration gradient.

Answer:

C. Active transport
