What else can I help you with?
What molecules help control movement of substances thought cell membranes?
how long after their discovery did it take the scientific community to accept the existence of cells
How do carrier proteins transport substances across membranes?
Carrier proteins bind to specific molecules on one side of the membrane, undergo a conformational change, and release the molecules on the other side. This process allows the substances to be transported across the membrane selectively.
Cell membranes that allow certain molecules to pass through while keeping others out are called?
semi permiable I believe, but I'm not 100 percent sure on the spelling selectively permeable
What two substances control the movement of materials into and out of cell?
Some of the proteins and lipids do control movement of materials into and out of the cell.
What does the fluid bilayer do?
The fluid bilayer, composed of phospholipids, forms the basic structure of cell membranes. It acts as a barrier to control the movement of substances in and out of the cell, helping to maintain cellular homeostasis. Additionally, the fluidity of the bilayer allows for flexibility and dynamic interactions with proteins and other molecules within the cell membrane.

What are the differences between hydrophilic and hydrophobic cell membranes and how do these differences impact the movement of molecules across the membrane?
Hydrophilic cell membranes are attracted to water, while hydrophobic cell membranes repel water. The differences impact the movement of molecules across the membrane because hydrophilic molecules can easily pass through hydrophilic membranes, while hydrophobic molecules can pass through hydrophobic membranes. This selective permeability allows the cell to control what substances enter and exit.
What allows a cell to control what substance pass into and out of it?
Cell membranes are selectively permeable, meaning they control what substances can pass through based on size and charge. This is achieved through membrane proteins and channels that facilitate the movement of specific molecules in and out of the cell. Additionally, active transport processes such as pumps and vesicle transport mechanisms also help regulate the movement of substances across the cell membrane.
What do living systems have that separates the internal chemicals from the external chemical environment?
Living systems have cell membranes that separate internal chemicals from the external chemical environment. These membranes control the movement of substances in and out of the cell, allowing for selective exchange of molecules and maintaining internal conditions necessary for life.
What organelles control the movement of substances moving in and out the cells?
Cell membranes regulate the movement of substances in and out of cells through processes such as diffusion, osmosis, and active transport. Additionally, organelles like the endoplasmic reticulum and the Golgi apparatus are involved in packaging and transporting substances within the cell.
How do cell membranes work to regulate the movement of substances in and out of cells?
Cell membranes are made up of a double layer of lipids with proteins embedded in them. These proteins act as channels and pumps that control the movement of substances in and out of the cell. The membrane is selectively permeable, allowing some substances to pass through while blocking others. This helps maintain the cell's internal environment and regulate the flow of nutrients and waste products.
How do carrier proteins transport substances across membranes?
Carrier proteins bind to specific molecules on one side of the membrane, undergo a conformational change, and release the molecules on the other side. This process allows the substances to be transported across the membrane selectively.
Controls what moves into cells?
Cell membranes control what moves into cells by selectively allowing certain substances to pass through while blocking others. This selectivity is maintained through various processes such as diffusion, facilitated diffusion, and active transport. Additionally, cell membranes contain specific transport proteins and channels that help regulate the movement of molecules in and out of the cell.
