Next lesson. Meaning: n. transport of a substance across a cell membrane by diffusion; expenditure of energy is not required. Similar words: active transport, transport, air transport, transportable, means of transportation, transportation, public transport, passport. Active transport is called "active" because this type of transport requires energy to move molecules.

Active and Passive Voice Comparison. The key difference between active transport and facilitated diffusion is that the active transport occurs against the concentration gradient hence, utilizes energy to transport molecules across the membrane while the facilitated diffusion occurs along the concentration gradient hence, does not utilize energy to transport molecules across the membrane. ... An agreement was made between the doge and the envoys, by which transport and active help were to be given by Venice in return for 85,000 marks and the cession of half of the conquests made by the crusaders. : Membranes control the composition of cells by active and passive transport. active transport The movement of ions or molecules across a cell membrane in the direction opposite that of diffusion, that is, from an area of lower concentration to one of higher concentration. Active transport is the process by which materials move from a lower concentration to a higher concentration. ‘Complex processes regulate both passive and active transport across the nuclear membrane.’ More example sentences ‘The electrocytes establish a charge difference across the cell membranes, presumably by active transport of ions.’ Decreasing consumption of high-sugar drinks while increasing water consumption and increasing active transport--haven'. This page has lots of examples and an interactive test on active sentences. Passive transport, also known as passive diffusion, is a process by which an ion or molecule passes through a cell wall via a concentration gradient, or from an area of high concentration to an area of low concentration.It’s like moving from the train to the platform of a subway station, or stepping out of a crowded room. 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. : This clearance was mediated by both active and passive transport processes. In the active transport, the molecules are carried from the region of lower concentration gradient to the region of the higher concentration gradient.In this process, the molecules are the pump in the upward direction, and it is the unidirectional process, and therefore this process requires energy in the form of ATP also known as Adenosine triphosphate. Define passive transport. 48. transport example sentences. Sentences Menu. Students will explore the material through a video lesson, demonstrations, discussions and a hands-on, group activity. Copyright © 2016 sentencedict.com All Rights Reserved Contact: Meaning: n. transport of a substance (as a protein or drug) across a cell membrane against the concentration gradient; requires an expenditure of energy. Active transport is the movement of dissolved molecules into or out of a cell through the cell membrane, from a region of lower concentration to a region of higher concentration. Active transport requires the assistance of a type of protein called a … Practice: Facilitated diffusion. 179. Active transport is the movement of particles across a cellular membrane from a lower to a higher concentration by the use of metabolic energy. In general terms, active transport refers to a substance moving from areas in which it has low concentration to an area with high concentration, and the substance is generally one that a cell needs for sustenance, like amino acids, ions or glucose. An active sentence is the opposite of a passive sentence. ATP is the most common source of energy for active transport. (2) It is easy enough to assert that active transport across membranes occurs, but much harder to explain how. 83. It's still active but it goes to voice mail. While voluntary dispersion may not often occur, animal dispersion occasionally does, as dispersion over large distances is likely to be passive transport by bats or other vertebrates. Active transport of H + ATPases alters membrane potential allowing for facilitated passive transport of particular ions such as Potassium down their charge gradient through … Definition of active transport.

Definition of Active Transport. The movement of ions or molecules across a cell membrane in the direction opposite that of diffusion, that is, from an area of lower concentration to one of higher concentration.
