Active Transport Active Transport requires the cell to use energy, usually in the form of ATP. Active Transport creates a charge gradient in the cell membrane. For example in the mitochondrion, hydrogen ion pumps pump hydrogen ions into the intermembrane space of the organelle as part of making ATP.

Passive transport is the movement of substances across the membrane without any input of energy from the cell. Osmosis and diffusion (the focus of the previous lesson) are two examples of passive transport.
The main types of movement across membranes are simple diffusion, facilitated diffusion, Osmosis, Active Transport and Bulk Transport (including exocytosis and endocytosis). It is sometimes described as types of transport through cell membranes. Knowledge about cell membranes is required for many courses in cell biology and biology in general.

Active transport is the movement of ions or molecules across a cell membrane into a region of higher concentration, assisted by enzymes and requiring energy; whereas, passive transport is a movement of biochemicals and other atomic or molecular substances across cell membranes.
In summary, we have learned that active transport is transport that requires chemical energy to move substances against a concentration gradient. There are three types of integral membrane

Active transport is the energy-demanding transfer of a substance across a cell membrane against its concentration gradient, i.e., from lower concentration to higher concentration. Special proteins within the cell membrane act as specific protein ‘carriers’.
2 Active transport The cell membrane also contains protein carrier molecules which can use energy to actively move molecules and ions through the membrane.

Section Summary. Active transport methods require the direct use of ATP to fuel the transport. Large particles, such as macromolecules, parts of cells, or whole cells, can be engulfed by other cells in a process called phagocytosis.

Figure 1. Mechanisms of solute transport. Three distinct types of passive transport, as well as active transport, are illustrated. Passive transport is the movement of solute across a membrane down an electrochemical gradient (from the side of the membrane with a high concentration of solute to the side with a low concentration).
Transport systems may be passive or active. Passive transport proteins may be channels or facilitative transporters. Active transporters may be primary active transporters (pumps) or secondary active transporters (cotransporters and exchangers). See text for details.

Facilitated diffusion and active transport are two ways of moving materials across the cell membrane. These two types of transport have many similarities as well as differences.

Primary active transport, also called direct active transport, directly uses energy to transport molecules across a membrane. Example:Sodium-potassium pump, which helps …
Active transport is important for cellular function because it moves important items, such as calcium and glucose, into and out of cells. Proteins sit on the cell membrane, with one part inside and one part outside the membrane.
Difference Between Passive and Active Transport The main difference is the fact that passive transport does not require any energy, whereas active transport requires energy for movement. Passive transport is basically along the concentration gradient, and is mostly dependent on the permeability of the cell membrane structure.

Primary active transport utilizes energy in form of ATP to transport molecules across a membrane against their concentration gradient. Therefore, all groups of ATP-powered pumps contain one or more binding sites for ATP, which are always present on the cytosolic face of the membrane.
Active and passive transport are biological processes that move oxygen, water and nutrients into cells and remove waste products. Active transport requires chemical energy because it is the movement of biochemicals from areas of lower concentration to areas of higher concentration.

Active and passive transport processes are two ways molecules and other materials move in and out of cells and cross intracellular membranes. Active transport is the movement of molecules or ions against a concentration gradient (from an area of lower to higher concentration), which does not ordinarily occur, so enzymes and energy are required.
There are two types of transport: active transport, and passive transport. Passive transport is easiest for the cells because they don’t need to use any energy to make it happen. Diffusion is the simplest and most common form of passive transport. During the diffusion process, tiny particles of the materials that need to be delivered to the cells are spread through either a gas, like oxygen

Why Is Active Transport Important? Reference.com
Transport across a cell membrane is a tightly regulated process, because cell function is highly dependent on maintain strict concentrations of various molecules. When a molecule moves down its concentration gradient is it participating in passive transport; moving up the concentration gradient requires energy making it active transport.

active transport is especially important in maintaining ion concentration in cells and between cells. Carrier proteins first binds with a particle of the substance to be transported. Carrier protein must be a similar shape that fits the molecule or ion that it is binding to.
The three major classes of membrane transport proteins are depicted in Figure 15-3a. All are integral transmembrane proteins and exhibit a high degree of specificity for the substance transported. The rate of transport by the three types differs considerably owing to differences in their mechanism of action. Figure 15-3Schematic diagrams illustrating action of membrane transport

Passive transport is the cellular process of moving molecules and other substances across membranes. Passive transport differs from active transport in that it does not involve any chemical energy. Rather, passive transport relies on the innate permeability of the cell membrane and its component proteins and lipids.
