Which type of membrane protein attaches to specific hormones such as insulin?
The type of membrane protein that attaches to specific hormones such as insulin is a receptor protein. Receptor proteins are specialized proteins located on the cell membrane that recognize and bind to specific molecules such as hormones, triggering a cellular response. In the case of insulin, its receptor protein on the cell membrane binds to insulin, leading to cellular uptake of glucose and other metabolic responses.
What does a carrier protein do in the process of transporting molecules across a cell membrane?
A carrier protein helps transport molecules across a cell membrane by binding to specific molecules and changing shape to move them across the membrane.
What substances would most likely require a protein to facilitate its diffusion across a cell membrane?
Quick answer: glucose Explanation: Any substance that the membrane selects against requires integral proteins to cross the membrane. B/c the lipid bilayer is selectively permeable, not all substances can pass through it by diffusion or osmosis. However, when the cell requires a substance that it's membrane does not easily allow to pass through, it must enter via the proteins in the membrane. They can either be carrier proteins or protein channels depending on the substance. One example of a substance which requires facilitated diffusion is glucose.
What is a type of protein found in the cell membrane which regulates the coming and going of substances into or out of the cell?
Channel proteins are a type of protein found in the cell membrane that regulate the passage of specific ions or molecules into or out of the cell. These proteins form channels or pores that allow substances to pass through the membrane, controlling the movement of substances across the cell membrane.
What protein is an integral membrane protein that helps move molecules across a cell membrane?
An example of an integral membrane protein that helps move molecules across a cell membrane is a transporter protein. These proteins are embedded within the lipid bilayer and facilitate the movement of specific molecules such as ions or metabolites across the membrane through a process called facilitated diffusion or active transport.
What substance can pass through a capillary membrane?
plasma protein
How do carrier proteins transport substance across the membrane?
The carrier protein changes shape , shielding the molecule from the interior of the membrane.
Which type of membrane protein attaches to specific hormones such as insulin?
The type of membrane protein that attaches to specific hormones such as insulin is a receptor protein. Receptor proteins are specialized proteins located on the cell membrane that recognize and bind to specific molecules such as hormones, triggering a cellular response. In the case of insulin, its receptor protein on the cell membrane binds to insulin, leading to cellular uptake of glucose and other metabolic responses.
How. do carriers proteins transport substances across cell membranes?
Carrier Proteins transport molecules from an area of higher concentration on one side of the membrane to an area of lower concentration on the other side.
What is A transporter protein that carries a substance across a cellular membrane against its concentration gradient?
pump

What happens during the process of faciltated diffusion?
An Integral Membrane Protein Assists A Specific Substances Across The Membrane.
What is a large protein in the cell membrane that transports a specific ion?
Ion channel
A protein on the cell membrane that recognizes and binds to specific substances is called a?
