When a cell takes in substances through endocytosis the outside of the cell membrane becomes the inside of the vesicle. what might this suggest about the structure of the cell membrane?

This suggests that the cell membrane is a dynamic structure that can bend and invaginate to form vesicles during endocytosis. It is composed of a phospholipid bilayer with hydrophilic heads facing the aqueous environments (inside and outside) and hydrophobic tails sandwiched in between. The ability of the cell membrane to undergo endocytosis implies its flexibility and capability to change shape.

When the cell membrane becomes a vesicle?
endocytosis
What would happen if the cell wasn't permeable?
the cell membrane is not completely permeable.This allows substances in and out of the cell and only a few substances could get into the cell.If the cell membrane becomes permeable any substance including the bad ones will get in easily this could destroy the cell.
What are cell membranes and cell wall composed of?
The cell membrane and the cell wall is are composed of two different things. The cell membrane is made from phospholipid bilayers that becomes flexible by cholesterols. The cell wall is a rigid structure that surrounds the cell membrane that is either composed of cellulose, chitin, or peptidoglycan depending on the cell.
What is the effect of heat on beetroot?
The effect of heat on beetroot is that the membrane becomes impacted. It causes the membrane to be more permeable.
What causes cell membrane to depolarize?
It's during the "rising phase" when the membrane potential becomes more positive.
When the cell membrane becomes a vesicle?
endocytosis
A cell conducts endocytosis by what?
Cells perform endocytosis through membrane movement. Endocytosis is a type of Bulk Transport, which involves the movement of larger particles (vesicles) through the membrane in and out. Endocytosis involves Phagocytosis or Pintocytosis. Phagocytosis: when cells engulf particles via pseudopodia ("false feet"), which is packaged in the membrane into an enclosed sac, and once inside the cell, it becomes a vacuole. Pintocytosis: when cells GULP extracellular fluids and makes them into vesicles. The fluids are unimportant but gulped anyway for the molecules within it.
How do cells move large molecules into and out of the cell?
Large molecules are typically moved into the cell during a process called "endocytosis". During this process, a molecule binds to a "receptor" protein, a cell surface protein which is anchored within the cell membrane. The cell then begins to fold the membrane inward, forming a pocket called an "invagination" which contains the molecule bound to the receptor. Eventually, the invagination pinches off the cell membrane and becomes a small vacuole, or an "endosome". These endosomes can be moved throughout the cell to where the large molecules are needed or processed. If the large molecule is needed within the cytoplasm, it is transported out of the endosome through a protein complex that forms a pore across the endosome membrane. These transport processes all require the use of ATP.

What is membrane gelling?
Membrane gelling is when a membrane becomes solid, for example at low temperatures.
If a resting potential becomes more negative what happens to the cell?
When the membrane potential becomes more negative it is being hyperpolarized. Remember the resting membrane potential is already at a negative state (~70mV). So if you are making a comparison of a membrane potential that is hyperpolarized in comparison to a resting membrane potential, the resting membrane potential is said to be more depolarized.When the membrane potential becomes more positive it is called depolarization.

A large particle can enter a cell by an active transport process called?
Endocytosis - the way in which cells take in food and other materials. The cells membrane wraps around the particle it needs on its outside, ingesting it. This then becomes trapped within a vacuole inside the cells cytoplasm where it is broken down, digested, and absorbed by enzymes.
What disorder occurs in juvenile arthritis?
the synovial membrane becomes intensely inflamed. Usually thin and delicate, the synovium becomes thick and stiff, with numerous infoldings on its surface. The membrane becomes invaded by white blood cells
How does a cell move a molecule that is too large for transport?
I assume that you mean "how does a large molecule enter or leave a cell, when it is too large to diffuse through the cell membrane or to be transported by transmembrane transporter proteins?" If this is the case, then the cell must actively (i.e. with energy in the form of ATP/GTP) import/export the macromolecule (large molecule) via endocytosis/exocytosis. 1. Endocytosis and 2. exocytosis are when the cell either: 1. engulfs the macromolecule in a membrane, forming a vesicle around it, which is snipped internally, leaving the vesicle and its contents inside the cell; 2. or, the macromolecule is packaged into a vesicle by the Golgi apparatus, the vesicle meets the cell membrane and fuses to it, opening up, and the contents are expelled outwards while the vesicle membrane becomes part of the cell membrane. There are many diagrams available on the internet that illustrate this process. I hope this helped.
