What results in a defect in membrane proteins that normally function in chloride ion transport?
Defects in membrane proteins that normally function in chloride ion transport can result from mutations in genes coding for those proteins. These mutations can lead to altered protein structure or function, affecting the ability of the protein to transport chloride ions across the membrane correctly. This can result in conditions such as cystic fibrosis, where mutations in the CFTR gene lead to defective chloride ion transport.

Which molecules do not normally cross the nuclear membrane?
Large molecules such as proteins and RNA do not normally cross the nuclear membrane. They require specific transport mechanisms, such as nuclear pores, to move between the nucleus and the cytoplasm. This selective transport ensures that only specific molecules can enter or exit the nucleus.
What is the opposite of active transport?
The opposite is normally inactive.For people, the opposite of active can be slothful, lax, idle, or indolent.For volcanoes, the opposite could be dormant or even extinct.For sentences, the opposite of the active voice is passive.
Through which process does a root normally obtain minerals?
Roots typically obtain minerals through the process of active transport, where they actively transport mineral ions from the soil into the root cells against a concentration gradient. This process requires energy in the form of ATP and specialized transport proteins in the cell membrane of the root cells.
Which type of transport normally goes from a low concentration to a high concentration?
active transport
Is glucose molecule passive or active transport?
Secondary active transport aka facilitated diffusion [depending on your teacher].
This results from a defect in membrane proteins that normally function in chloride ion transport?
Cystic Fibrosis

Why transport proteins require energy to function in active transport?
Because there is a higher concentration inside the cell then out side ....because it requires energy to move the molecules outside in a different direction then they would normally move, it is like riding a bike up a hill it requires energy.

What cell have a cell membrane?
normally prokaryotic do not cells have a cell membrane. eukaryotic cells do.

active transport
What is the name of the ionic compound Cu2Ci2?
Cu2Cl2 is cuprous chloride or copper(I) chloride, and the formula is normally written as CuCl.
Does magnesuim increase progesterone?
The magnesium chloride is normally present in the cell. It does not affect the progesterone level, normally.
What does facilitated diffusion do in a cell?
It allows for the flow of substances which are normally too large to pass through the cell membrane. Like active transport, it accomplishes this using channel proteins coded for each specific substance (sugar, for example). Unlike active transport, facilitated diffusion only works WITH the osmotic pressure gradient, not against.
What mechanism does a cell use to move small potassium molecules into the cell against the concentration gradient?
Cells use active transport mechanisms, such as the sodium-potassium pump, to move potassium ions against their concentration gradient into the cell. This pump utilizes the energy from ATP hydrolysis to actively transport sodium out of the cell and potassium into the cell, maintaining the concentration gradient for potassium.
What does the active trasport do?
Normally things move from a side with a high concentration to a low concentration until both are equal. You can see this if you put a spoonful of dry cool aid into water. After a time, all the water has equal amounts of the colored cool aid. This is called passive transport (or osmosis). Active transport occurs in one area that has a higher concentration, the concentration becomes higher still. This can occur in a cell and requires a membrane that separates the sides and has "pumps" in the membrane that keep the two sides from mixing and becoming equal. The pumps in the membrane are proteins.
