Detailed explanation-1: -This statement is true. The main difference between active and passive transport is that in active transport, solutes are moved from an area of low to high concentration (against the concentration gradient), and requires the energy released from ATP hydrolysis.
Detailed explanation-2: -During active transport, substances move against the concentration gradient, from an area of low concentration to an area of high concentration. This process is “active” because it requires the use of energy (usually in the form of ATP).
Detailed explanation-3: -Active transport is defined as movement of a solute from a region of low electrochemical potential on one side of the cell membrane to a region of higher electrochemical potential on the opposite side.
Detailed explanation-4: -Active transport occurs across the plasma membrane against the concentration gradient from their lower to higher concentration. It requires ATP. So it is an energy dependent process.
Detailed explanation-5: -In active transport, the particles move across a cell membrane from a lower concentration to a higher concentration. Active transport is the energy-requiring process of pumping molecules and ions across membranes “uphill”-against a concentration gradient.
