Which is the best definition of active transport?
In cellular biology, active transport is the movement of molecules across a cell membrane from a region of lower concentration to a region of higher concentration—against the concentration gradient. Active transport requires cellular energy to achieve this movement.
What is an active transport process?
Active transport is the energy-requiring process of pumping molecules and ions across membranes "uphill" - against a concentration gradient. The active transport of small molecules or ions across a cell membrane is generally carried out by transport proteins that are found in the membrane.
What is active transport simplified?
Active transport is when molecules move across a cell membrane from a lower concentration to a higher concentration. This takes energy, often from adenosine triphosphate (ATP). Active transport is done so cells get what they need, such as ions, glucose and amino acids.
What is active transport in biology class 9?
In cellular biology, active transport is the movement of molecules across a cell membrane from a region of lower concentration to a region of higher concentration—against the concentration gradient. ... Active transport requires cellular energy to achieve this movement.
What do you mean by active transport Class 9?
What is Active Transport? “Active Transport is defined as a process that involves the movement of molecules from a region of lower concentration to a region of higher concentration against a gradient or an obstacle with the use of external energy.”
Which is implied by active transport?
The correct option is d Transport against concentration gradient.
What is active transport in physiology?
Active transport is an energy-driven process where membrane proteins transport molecules across cells, mainly classified as either primary or secondary, based on how energy is coupled to fuel these mechanisms.
What is an active transport quizlet?
Only $35.99/year. What is active transport? The movement of particles through a membrane against the concentration gradient with the expenditure of energy and aided by a protein carrier.
What is active transport and passive transport?
Active transport moves molecules and ions from lower concentration to higher concentration with the help of energy in the form of ATP. On the other hand, passive transport moves molecules and ions from a higher concentration to lower concentration without any energy.
What is different between active and passive transport?
In Active transport the molecules are moved across the cell membrane, pumping the molecules against the concentration gradient using ATP (energy). In Passive transport, the molecules are moved within and across the cell membrane and thus transporting it through the concentration gradient, without using ATP (energy).
What is active transport in digestion?
Active transport is a process that is required to move molecules against a concentration gradient. The process requires energy. ... The glucose molecules in the intestine might be in a higher concentration than in the intestinal cells and blood – for instance, after a sugary meal.
What are 3 types of active transport?
Carrier Proteins for Active Transport
There are three types of these proteins or transporters: uniporters, symporters, and antiporters . A uniporter carries one specific ion or molecule. A symporter carries two different ions or molecules, both in the same direction.
What is the main function of active transport?
The main function of active transport is to transport molecules against the concentration gradient.
