Active transport is not a carrier of protein; rather, it is a cellular process that moves molecules across a membrane against their concentration gradient, often requiring energy in the form of ATP. This process can involve transport proteins, such as pumps and carriers, that facilitate the movement of ions and small molecules. While proteins themselves can be involved in active transport, the term "active transport" refers specifically to the mechanism rather than the transport of proteins.
What else can I help you with?
Through what type of proteins does active transport occur?
Active transport occurs through carrier proteins that pump molecules against their concentration gradient using energy from ATP. These carrier proteins undergo conformational changes to transport molecules across the cell membrane.
Is carrier mediated passive or active?
Carrier-mediated transport can be either passive or active, depending on the type of carrier protein involved. Passive carrier-mediated transport allows molecules to move down their concentration gradient without requiring energy input, while active carrier-mediated transport moves molecules against their concentration gradient using energy from ATP or an electrochemical gradient.
Is a carrier protein an active transport or a passive transport?
They are used in both, in passive the molecules move in , then change the shape then leave and the entering and leaving are both by diffusion. in active transport molecules move in by diffusion, change the shape of the carrier protein, then because theyre moving into the cell where the molecule is in higher concentration energy is required to push the molecules out of the carrier proteins, this energy comes from ATP which is supplied to the carrier proteins.
What happens in each of the three main parts of facilitated diffusion?
Binding: Molecules from the extracellular environment bind to the carrier protein on the cell membrane. Transportation: The carrier protein undergoes a conformational change, allowing the molecules to pass through the membrane. Release: Once inside the cell, the molecules are released from the carrier protein and the protein returns to its original conformation for further transport.
What process involves the use of specific carrier molecules?
Active transport is the process that involves the use of specific carrier molecules to move substances across a cell membrane against their concentration gradient. These carrier molecules enable the movement of molecules or ions into or out of the cell by binding to the specific substance and undergoing a conformational change.
Through what type of proteins does active transport occur?
Active transport occurs through carrier proteins that pump molecules against their concentration gradient using energy from ATP. These carrier proteins undergo conformational changes to transport molecules across the cell membrane.
How do carrier protein recognize substances to transport in active transport?
substance to pass
Is carrier proteins passive transport or active transport?
Carrier proteins can use active or passive transport depending on what type of carrier protein it is (meaning what the protein transports). The form of passive transport that they use is facilitated diffusion. An example of active transport is the Sodium Potassium pump. Active transport requires ATP. Facilitated diffusion is used to transport polar molecules and ions that cannot directly cross the cell membrane. Facilitated diffusion doesn't require energy.
Primary active transport involves a conformational change in the carrier protein The most immediate stimulus for this is?
The most immediate stimulus for the conformational change in the carrier protein in primary active transport is the binding of ATP or another source of chemical energy. This energy is used to pump molecules against their concentration gradient.
What is active absorption?
requires the input of energy and a carrier protein to move nutrients across a concentration gradient
Is the sodium potassium pump a carrier protein?
the carrier protein of Na-k pump is an ion carrier protein and the pump cannot be termed as the carrier protein its a biochemical phenomenon
Is carrier mediated passive or active?
Carrier-mediated transport can be either passive or active, depending on the type of carrier protein involved. Passive carrier-mediated transport allows molecules to move down their concentration gradient without requiring energy input, while active carrier-mediated transport moves molecules against their concentration gradient using energy from ATP or an electrochemical gradient.

Is it true that the cell mechanism of active transport involves the transport of insoluble chemicals across the membrane with protein acting as the carrier?
yes
What process involves the use of specific carrier molecules?
Active transport is the process that involves the use of specific carrier molecules to move substances across a cell membrane against their concentration gradient. These carrier molecules enable the movement of molecules or ions into or out of the cell by binding to the specific substance and undergoing a conformational change.
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.
