What else can I help you with?
Where can phospholipids move and allow water?
freely and allow water and other hydrophylic molecules to pass through into or out of the cell.
Substances that can pass through cell membranes by diffusion include?
Small molecules such as oxygen, carbon dioxide, and water can pass through cell membranes by diffusion. Lipid-soluble molecules like alcohol and steroid hormones can also diffuse through cell membranes.
What type of molecules embebbed in the plasma membrane allows molecules to pass through the membrane by active or passive transport?
proteins
Does a permeable membrane will let substances pass through it?
Yes, a permeable membrane allows certain substances to pass through while blocking others based on their size and chemical properties. It enables the selective transport of molecules, ions, or particles across a barrier, such as in biological systems or in water filtration processes.
What is the term used for a layer that allows only certain molecules to pass through the cell membrane?
permiable
Is there a glass water can go through?
Yes, water can pass through glass since it is a porous material. This property allows water molecules to move through the tiny spaces between the glass molecules.
Where can phospholipids move and allow water?
freely and allow water and other hydrophylic molecules to pass through into or out of the cell.
Why does light go through water?
Light can pass through water because it is a transparent medium, meaning it allows light to travel through it relatively unobstructed. Water molecules do not absorb visible light, so it can pass through the water easily.
What types of membrane allow solvent molecules to pass through but do not allow solute molecules to pass through?
Reverse osmosis membranes are specifically designed to allow solvent molecules, such as water, to pass through while blocking solute molecules. These membranes are used in water purification processes to separate contaminants from water based on their molecular size.
What allows water to pass through?
water can pass through cell membranes by osmosis- similar to diffusion
Why can't water pass through the phospholipids?
Water cannot pass through phospholipids because phospholipid molecules have hydrophobic tails that repel water molecules, preventing them from passing through the lipid bilayer.
What structure allows sugar and water to pass through?
Cell membrane allows sugar and water to pass through due to the presence of transport proteins such as glucose transporters and aquaporins. These proteins facilitate the movement of these molecules across the cell membrane through passive or active transport processes.
What Semipermeable object that can pass through it what cannot?
A cell membrane is a semipermeable object that allows certain substances, such as water and small molecules, to pass through it while blocking larger molecules and ions. This selective permeability is important for controlling the movement of substances in and out of the cell.
What material allows air to come through but not water?
A material such as Gore-Tex or nylon ripstop is designed to be breathable, allowing air to pass through while repelling water. These materials have a porous structure that lets air molecules through while blocking larger water molecules.
What part of the cell membrane allows small molecules to pass through?
the cell membrane
What is meant by cell membrane is semipermeable?
It allows only certain molecules to pass through.
Substances that can pass through cell membranes by diffusion include?
Small molecules such as oxygen, carbon dioxide, and water can pass through cell membranes by diffusion. Lipid-soluble molecules like alcohol and steroid hormones can also diffuse through cell membranes.
