"In transport work, ATP drives the active transport of solutes across a membrane against their concentration gradient by phosphorylating transport proteins". (Solutes are transported.)

Save the animals!! :D

Plants donÕt have a circulatory system like animals, but they do have a sophisticated transport system for carrying water and dissolved solutes to different parts of the plant. This transport system includes Epidermis, Cortex, Vascular tissue, pith, and pericycle

In cotransport, a membrane protein couples the transport of two solutes.

Membrane transport is the collection of mechanisms that regulate the passage of solutes and small molecules through biological membranes.

PASSIVE TRANSPORT: when there is a transport of solutes from there higher concentration to their lower concentration across the semipermeable membrane as plasma membrane without any utilization of energy is called passive transport. ACTIVE TRANSPORT: When there is a net flow of solutes from there low concentration to their high concentrain of flow against the concentration gradiant with the utilization of energy is called active transport. e.g. Na+- K+ exchange pump.
