Molecules are moving against a 'concentration' gradient. Active transportation moving from low to high concentration, while passive transportation such as osmosis and diffusion go from high to low concentration.
Energy is needed for active transport because of cell membranes. In the cell membranes are ions, glucose and amino acids.

Passive transport and active transport are transport of materials across membranes. Passive requires no energy, while active does.
Active Transport
I believe it's active transport. active transport is correct.
The transport of a substance across the cell membrane against its concentration gradient is called active transport.
Active transport requires energy to move substances across a cell membrane against their gradient.
Active transport
Active transport
It is called active transport.
Passive transport and active transport are transport of materials across membranes. Passive requires no energy, while active does.
Active Transport
Active Transport is the passage of materials across the membrane through the expenditure of energy. Passive Transport is the passage of materials across the membrane without the expenditure of energy. Bulk Transport is the type of active transport. Diffusion and Osmosis are type of passive transport.
ATP is required for active transport.
Active Transport.
Active transport simply means the transport of substances against the concentration gradient.In this transport,ATP is utilised.
active transport requires energy to move stuff and the energy is ATP
