How do water-soluble molecules diffuse through the cell membrane?
Water-soluble molecules diffuse through the cell membrane by passing through protein channels or transporters that are embedded in the membrane. These channels and transporters allow the molecules to move across the membrane, from an area of high concentration to an area of low concentration, without requiring energy.
Which Organ is without lymphatic drainage?
The central nervous system does not have a lymphatic system for drainage. This is due to the presence of the blood-brain barrier, which restricts the movement of substances between the blood and the brain tissue, including lymphatic fluid.
What mechanism by which glucose can enter the cytoplasm without expending ATP is?
Facilitated diffusion is the mechanism by which glucose can enter the cytoplasm without expending ATP. This process uses specific membrane proteins called glucose transporters to facilitate the movement of glucose down its concentration gradient into the cell.
Does passive transport move substances against the concentration gradient?
No, passive transport does not move substances against the concentration gradient. It moves substances from an area of high concentration to an area of low concentration without requiring energy input.
Do any of the Cells lack a Cell membrane?
No, all cells have a cell membrane that acts as a protective barrier around the cell. It controls the movement of substances in and out of the cell, maintaining its internal environment. Without a cell membrane, the cell would not be able to survive.
What are auto transporters meant for?
Auto transporters are made to help people transport things without any issue. An auto transporter will transport something that you are wishing to take with you when you travel, for free and with no hassle.
What is a type of barrier that lets in all things?
A type of barrier that lets in all things is known as a "permeable barrier." This type of barrier allows the passage of various substances, including liquids, gases, and even small particles, without restriction. An example of this is a mesh screen or a porous material, which can facilitate the movement of air and water while blocking larger objects.
How can the sound barrier be broken without a plane?
With a whip...
What does sin barrera mean in English?
Without a barrier
What is the minimum height a step or platform can be without needing a barrier?
600mm
What substances combine without a chemical reaction?
Substances like oil and water can mix without undergoing a chemical reaction, forming a mixture. Similarly, sugar and water can dissolve into each other without a chemical reaction occurring. These are physical changes where the substances retain their original properties.
How do water-soluble molecules diffuse through the cell membrane?

These channels and transporters allow the molecules to move across the membrane, from an area of high concentration to an area of low concentration, without requiring energy.
Why should you place a piece of paper between the magnet and the substances?
Placing a piece of paper between a magnet and substances helps to prevent direct contact, which can interfere with the magnetic field's effectiveness. It also protects sensitive materials from potential damage due to the magnet's attraction or other forces. Additionally, the paper can act as a barrier, ensuring that any magnetic effects are transmitted more evenly to the substances without causing disruption or contamination.
What is it called when substances move past the membrane without using energy?
Passive transport is when substances move past the membrane without using any energy.
What is a characteristic of pure substances that can be observed without changing it into another substances?
lame people going wild
