May 16, 2020 · Active transport moves substances from a region of lower concentration to a higher concentration, i.e., against the concentration gradient. There is an energy requirement …

Aug 3, 2023 · Active transport is the energy-driven transportation of ions, small molecules, and solutes across the biological membrane against an electrochemical gradient (for ions) or …

May 5, 2022 · Active transport is a type of cellular transport in which substances (e.g. ions, glucose, and amino acids) are transported across a biological membrane towards the region …

Nov 22, 2025 · Active transport moves substances across a biological membrane against their concentration gradient. This process is often described as “uphill” movement because the …

Aug 23, 2025 · Active transport is a cellular process that moves molecules or ions across a cell membrane. This movement occurs against the natural flow or concentration gradient, from an …

In cellular biology, active transport is the movement of molecules or ions across a cell membrane from a region of lower concentration to a region of higher concentration—against the …

Mar 19, 2022 · Active transport moves ions and molecule against the concentration gradient (from lower to higher concentration), while passive transport moves chemicals from higher to lower …

Feb 2, 2023 · Active transport is an energy or ATP-dependent, cellular transport process that selectively moves substances from an area of low concentration to an area of high …

Active transport is a vital cellular process that enables organisms to move substances across cell membranes against their concentration gradients, requiring energy input in the form of …

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 …
