Which molecules help control movement of substances through cell membranes?
Proteins such as transporters, channels, and pumps are the main molecules that help control the movement of substances through cell membranes. These proteins facilitate the selective transport of ions, molecules, and other substances into and out of cells, maintaining proper cellular function. Additionally, phospholipids in the membrane also play a role in regulating the movement of substances across the cell membrane.
What is methods of puryfying mixtures?
Methods of purifying mixtures include filtration, which separates solids from liquids using a filter; distillation, which separates components based on differences in boiling points; and chromatography, which separates substances based on their movement through a medium. Other techniques like centrifugation utilize centrifugal force to separate components of different densities. Each method is chosen based on the physical and chemical properties of the mixture's components.
What are the special doorways in the cell membrane made of?
Special doorways in the cell membrane are made of proteins called ion channels or transporters. These proteins allow specific ions or molecules to pass through the cell membrane, regulating the movement of substances in and out of the cell.
What are the special structures in the cell membrane that allow materials such as water and sugar to pass through made o?
The special structures in the cell membrane that allow materials like water and sugar to pass through are proteins called transport proteins. These proteins help facilitate the movement of specific molecules across the membrane by acting as channels or carriers. They play a crucial role in regulating the flow of substances in and out of the cell.
Through which organelle do substances enter or leave a cell?
Substances pass through the plasma membrane, although ot is not technically an organelle.
Movement of energy through substances in longitudinal waves is what?
It is sound waves

Is thermal the movement of energy through substances in longitudinal waves?
No, it is totally unrelated to that.

What is the movement of substances through a cell membrane without the use of cell energy?
passive transport
What are the three changes that causes heat in substances?
1. melting 2.boiling 3.freezing
Which mmolecules help control movement of substances through cell mmembrans?
Carrier proteins or transport proteins.
How does the process of flux through a membrane contribute to the movement of substances across biological barriers?
The process of flux through a membrane helps substances move across biological barriers by allowing them to pass through the membrane from an area of high concentration to an area of low concentration. This movement is driven by the natural tendency of substances to reach equilibrium, where the concentration is the same on both sides of the membrane.
What separates the cell from its surroundings and selects what can and can't enter?
The cell membrane separates the cell from its surroundings and controls what can enter and exit the cell through a selective barrier called the lipid bilayer. This barrier allows certain substances, such as nutrients and waste, to pass through while blocking others.
The movement of energy through substances in longitudinal waves is?
The movement of energy through substances in longitudinal waves is characterized by the vibration of particles in the same direction as the wave's propagation. This results in a series of compressions and rarefactions in the medium. Sound waves are a common example of longitudinal waves.
