Which two kinds of molecules combine to form cell membranes?
Lipids and proteins are two kinds of molecules that combine to form cell membranes. Lipids make up the majority of the membrane structure, creating a phospholipid bilayer, while proteins are embedded in the lipid bilayer and play various roles in cell function.
What is a structure that directs the work of a cell?
Cell membraine
What are the two outer layers of the plant?
cell wall and cell membraine
How do unicellular organisms do respiration?
diffusion of gases through the cell membraine.
What structuregive support and surrounds the plant cell membraine?
That would be the plant's cell wall made of cellulose.
What is a cell wall used for on a plant cell?
To protect the cell from foreign bodies. Hope this helped, by the way animal cells have a cell membraine no cell wall ;(
How many different kinds of protein molecules in a typical cell?
1000
What are the two main kinds of movement that happens into and out of the cell?
Ions and molecules move into and out of the cell by two main methods:Passive transport does not require any energy. Molecules wither diffuse into the cell or enter the cell via transporter proteins located on the cell membrane.Active transport requires the use of ATP molecules to move ions or molecules into and out of the cell.
What kinds of molecules, including the keyword, face difficulty in passing through a cell membrane?
Large or polar molecules, such as proteins or carbohydrates, face difficulty in passing through a cell membrane due to their size or charge.
In what type of passive cell membrane transport do carrier proteins combine with specific molecules to assist them across the membrane?
Facilitated Diffusion
Does molecules have cell?
No, molecules do not have cell, rather a cell have molecules in it.
What combines both exocytosis and endocytosis?
Transcytosis is a cellular process that combines both exocytosis and endocytosis. It involves the uptake of molecules into the cell through endocytosis, their transport across the cell, and then the release of these molecules through exocytosis on the opposite side of the cell.
