Carrier proteins are the transporters of active transport. They are stereohemically conformed in such a way as to facilitate the movement of specific chemicals across celll membrances.
Each carrier protein is designed to recognize only one substance or one group of very similar substances. The molecule or ion to be transported (the substrate) must first bind at a binding site at the carrier molecule, with a certain binding affinity. Following binding, and while the binding site is facing, say, outwards, the carrier will capture or occlude (take in and retain) the substrate within its molecular structure and cause an internal translocation, so that it now faces the other side of the membrane. The substrate is finally released at that site, according to its binding affinity there. All steps are reversible.
For example: Diffusion of sugars, amino acids,nucleoside.
Uptake of glucose
Transportation of salts, glucose, and amino acids

What is a carrier protein?
A carrier protein is a type of protein that helps transport specific molecules across cell membranes. These proteins bind to molecules on one side of the membrane and release them on the other side, facilitating their movement into or out of cells. Carrier proteins play a crucial role in maintaining cellular function by regulating the transport of essential molecules.
What is an activated carrier and how does it function in biological processes?
An activated carrier is a molecule that temporarily stores and transfers energy in biological processes. It functions by carrying high-energy chemical groups, such as ATP or NADH, to different reactions in the cell where they can be used to drive essential processes like metabolism and cell signaling.
Does the nucleic acid ATP function as an energy carrier in the cell?
Yes, ATP (adenosine triphosphate) functions as an energy carrier in the cell by storing and transferring energy within cells for various cellular processes. It is the primary energy currency of the cell and is crucial for activities such as metabolism, muscle contraction, and cell division.
What functions do carrier proteins perform in active transport?
Carrier proteins in active transport actively pump molecules or ions against their concentration gradient across a cell membrane using energy from ATP. They allow specific substances to be moved across the membrane in a controlled manner, helping to maintain cellular homeostasis and regulate cell function.
The energy carrier NAD is reduced to what substance?
NAD is an energy carrier which is involved in the process of glycolysis. It is reduced to NADH when a hydrogen atom is added.
What molecules function as carrier in human blood circulation system?
Hemoglobin molecules function as the carrier in the human blood circulation system.
Function of a chromosomes?
Chromosomes are carrier of heredity material
What is the function of slotted brass masses on carrier?
to dance to the harlem shake,
Do hemoglobin function as carrier in the human blood circulation system?
Yes
How demodulator works?
a demodulator sole function is to restore the original modulating signal. it works by removing the Carrier

What is the function of the squid's stomach?
The squid's stomach acts like a carrier to hold food as receive digestional juices to break it down.
What function does a mitohondrion perform?
The mitochondria carry out the process of aerobic respiration and produce the energy-carrier molecule ATP (adenosine triphosphate).
What is the function of stomach of squid?
The squid's stomach acts like a carrier to hold food as receive digestional juices to break it down.
What are comparison and contrast of the structure and function of channel proteins and carrier proteins?
channel proteins transport large molecules through the interior cell carrier proteins wait until energey is provided and move molecules out and inside the cell
An individual with a recessive allele for an undesirable trait is called?
A carrier. This individual may not show the undesirable trait, but can pass on the recessive allele to their offspring.
Can you buy a phone from eBay and get activated from US Cellular?
I'm not sure of the context of your question, so I will assume you are asking if you can activate a cellular phone in the US, as opposed to activating a US Cellular phone (which is a wireless network in the US). Here are the different scenarios on activating a cellular phone in the US:Activating a carrier-based phone with the same carrier--you can activate a carrier-based phone with the same carrier, even if the phone has been inactive for a long period of time. It is functional provided it can connect to the current bands in that network.Activating a carrier-based phone with another carrier--if the phone is locked (tied to a particular carrier), it will not function if you attempt to activate it with another carrier. If you are able to get the phone unlocked (either thru the carrier, manufacturer, or on your own), it might work with another carrier provided the phone can run on that other carrier's network bands.Activating an unlocked phone with any carrier (traditional and pre-paid)--most unlocked phones, and this is assuming they are designed to be used in multiple bands in the US and/or elsewhere, can be activated on most carriers.Activating a carrier-based phone with a pre-paid carrier--it is possible to activate a carrier-based phone with a pre-paid wireless carrier, assuming that carrier has bands that match what the carrier-based phone had previously. An example is the pre-paid carrier Straight Talk, which utilizes bands from the four major wireless carriers (AT&T, Verizon, T-Mobile, Sprint).
