How does ATP enable transport proteins to move ions across a cell membrane?
Once translated, proteins are dispersed throughout the cellular environment. This section covers the transport of a protein into a specific organelle--the mitochondria.
The cotransport of protein that allows two different stances to pass through a membrane in the same direction is?
Symport is the type of cotransport that allows two different solutes to pass through a membrane in the same direction. This process involves the transport of molecules or ions in the same direction across a membrane with the help of a carrier protein. It is also referred to as coupled transport.
The cell uses energy to transport glucose through the cell membrane?
Glucose moves across the cell membrane through facilitated diffusion. This type of transport uses protein carriers to assist glucose molecules across the cell membrane from an area of high concentration to an area of low concentration.
In order for a protein to be an integral protein it would have to be what?
An integral protein must be firmly embedded within a cell membrane, spanning across it from one side to the other. This positioning allows integral proteins to have both an extracellular and intracellular domain, contributing to their crucial role in cell signaling and transport.
What process changes the shape of transport proteins when a particle binds with it?
The process that changes the shape of transport proteins when a particle binds to it is called conformational change. This change in shape allows the protein to either open a channel for the particle to pass through or undergo a rotational movement to transfer the particle across the membrane.
What is the name of the protein found in erythrocytes that allows for respiratory gas transport?
Hemoglobin
The actual transport of protons by the proton pump is mediated by a transmembrane protein which undergoes a change in its?
conformation during the transport process. This conformation change allows the protein to alternately bind and release protons on opposite sides of the membrane, resulting in the movement of protons across the membrane against their concentration gradient.
What is a gated protein?
A gated protein is a protein that can open or close a gate in a cell membrane, regulating the flow of ions or molecules across the membrane. This process allows for the selective transport of specific substances in and out of cells, contributing to cellular function and signaling.
In what type of passive transport do protein channels assist molecules across the membrane?
In facilitated diffusion, protein channels assist molecules in crossing the cell membrane. This type of passive transport allows substances, such as ions and polar molecules, to move down their concentration gradient without using energy. The protein channels provide a pathway through the lipid bilayer, enabling the selective transport of specific molecules.

What are Different types of mechanics?
There are two main types of transport systems which are used to transport solutes across a cell membrane: passive transport and active transport. Passive transport is where a protein in the membrane simply provides a 'hole' in the membrane, which allows the solute to flow freely in both directions. In this case, the flow of the solute is determined entirely by the concentration gradient across the membrane, and no energy is input to aid the movement (hence the term passive). Active transport is where the protein in the membrane actually binds to the solute, and conformational changes in the protein shape literally carry the solute across the membrane, then release it on the other side. This mechanism is designed for situations where movement of solutes against their concentration gradient is required, and requires the input of energy. This energy can come from one of a few places: * Primary active transport involves deriving the energy required to move the solute from the hydrolysis of ATP (Adenosine Triphosphate). In this case, the protein acting as the carrier is referred to as an ATPAse. * Secondary active transport involves deriving the energy from the movement of another solute across the membrane. This second solute will be flowing in the direction of its concentration gradient, so energy is released as it crosses the membrane. This allows it to drive the conformational changes in the protein that carry the solute across.
What type of transport place when a protein allows an ion to enter a cell but no additional energy is needed?
facilitated
What is pump in active transport?
A pump in active transport refers to a protein pump found in cell membranes that uses energy, usually ATP, to actively transport molecules or ions against their concentration gradient. This process allows cells to regulate the concentration of substances inside the cell and is essential for maintaining proper cellular function. Examples include the sodium-potassium pump and the proton pump.
What process changes the shape of transport proteins when a particle binds with it?
The process that changes the shape of transport proteins when a particle binds to it is called conformational change. This change in shape allows the protein to either open a channel for the particle to pass through or undergo a rotational movement to transfer the particle across the membrane.
