What else can I help you with?
What happens if a molecule is too large to go through a membrane?
The molecule will be transported across the membrane by way of a transport protein or protein channel.
Large molecules are surrounded by the cell membrane and enter the cell?
Large molecules can enter cells through processes like endocytosis, where the cell membrane surrounds the molecule and engulfs it in a vesicle. This allows large molecules to be transported into the cell without crossing the lipid bilayer of the membrane.
A large protein needs to enter a cell to help the cell perform a function. Explain what process the cell must use to allow the protein to enter and why.?
The cell must use a process called endocytosis to allow the large protein to enter. This process involves the cell membrane engulfing the protein and forming a vesicle that brings it inside the cell. Endocytosis is necessary for large molecules, like proteins, because they cannot pass through the lipid bilayer of the cell membrane due to their size and polarity. Once inside, the protein can be utilized for various cellular functions.
What means that the transport protein makes it easier for a molecule that cannot directly cross the cell membrane to enter or exit a cell?
When a transport protein facilitates the movement of a molecule across the cell membrane, it acts as a channel or carrier that helps the molecule bypass the lipid bilayer, which is generally impermeable to large or polar substances. This process, known as facilitated diffusion, allows essential molecules, like glucose or ions, to enter or exit the cell efficiently without expending energy. By providing a pathway, transport proteins ensure that cells can maintain homeostasis and properly regulate their internal environment.
What is the process by which large molecules enter a cell through pouches in the membrane?
The process by which large molecules enter a cell through pouches in the membrane is called endocytosis. During endocytosis, the cell membrane forms a pouch around the molecule, encloses it, and brings it into the cell as a vesicle. This allows the cell to take in larger molecules that would not be able to pass through the membrane on their own.
Which parts of cell membrane would help a large protein molecule enter the cell?

What part of the membrane would help a large protein enter the cell?
globular proteins .
What part of the membrane would help large carbohydrate molecule enter the cell?
Globular proteins
Which part of the membrane would help large carbohydrate molecule enter the cell?
Globular proteins
What does facilitated diffusion?
A transport protein, a large polar molecule, a semi-permeable membrane and a concentration gradient.
Which part of the cell would help a large protein molecule enter cell?

Would help large carbohydrate molecule enter the cell?
Large carbohydrates such as glycogen, starch will not be transported in to the cell by cell membrane.
How do molecules that are too large to cross the membrance enter into the cell?
Large molecules can enter a cell through endocytosis, where the cell membrane folds around the molecule, forms a vesicle, and brings it into the cell. This process allows the cell to take in nutrients, signaling molecules, and other substances that are too large to pass through the membrane directly.
What structure is the statement below most likely referring to A large glucose molecule requires facilitated diffusion but an oxygen molecule does not?
A large glucose molecule requires facilitated diffusion but an oxygen molecule does not is a semipermeable membrane.
