What else can I help you with?
What might happen if a disease caused a plasma membrane to thicken?
If a disease caused a plasma membrane to thicken, it could disrupt the exchange of molecules in and out of the cell. This could lead to issues with cellular communication, nutrient uptake, and waste removal. Ultimately, it could result in cell dysfunction and potential cell death.
What process allows movement of molecules that are too large to pass through a call membrane?
The process that allows movement of large molecules across a cell membrane is called endocytosis. In this process, the cell membrane engulfs the large molecules, forming a vesicle that brings them into the cell. There are different types of endocytosis, including phagocytosis for solid particles and pinocytosis for liquids. This mechanism enables cells to intake substances that cannot directly pass through the lipid bilayer of the membrane.
What substance not permeable at the cell membrane?
Large polar molecules like glucose and ions such as sodium and potassium are not permeable through the cell membrane. These molecules require specific transport proteins or channels to facilitate their movement across the membrane.
Which terms identifies the process used by the cell to remove large molecules?
The process used by cells to remove large molecules is called endocytosis. Endocytosis involves the cell engulfing the molecules by forming a vesicle around them, which then moves the molecules into the cell for processing or removal.
What does exocytosis transport?
Exocytosis transports large molecules, such as proteins and lipids, out of the cell. These molecules are packaged into vesicles within the cell and then released to the external environment when the vesicles fuse with the cell membrane.
What is A cell moving particles with the use of energy is called?
Active transport: The movement of particles against the concentration gradient into or out of a cell. Bulk transport:The movement of large molecules into or out of the cell. Both of these require energy
What are 5 Mechanism of cellular exchange?
Passive diffusion: Movement of small, non-polar molecules across the cell membrane. Facilitated diffusion: Movement of specific molecules through protein channels in the cell membrane. Active transport: Movement of molecules against the concentration gradient using energy from ATP. Endocytosis: Uptake of large molecules or particles by the cell through invagination of the cell membrane. Exocytosis: Release of molecules or waste from the cell by fusion of vesicles with the cell membrane.
Movement of large molecules by formation of a vesicle?
This process is called endocytosis. It involves the ingestion of large molecules or particles by the cell through the formation of a vesicle. The vesicle is formed when the cell membrane engulfs the material to be transported, creating a membrane-bound sac within the cell.

If a disease caused a plasma membrane to thicken, it could disrupt the exchange of molecules in and out of the cell. This could lead to issues with cellular communication, nutrient uptake, and waste removal. Ultimately, it could result in cell dysfunction and potential cell death.
Which terms identifies the process used by the cell to bring in large molecules?
Endocytosis is the provess used by the cell to bring in large molecules.
Which terms identify the process used by the cell to removed large molecules?
Exocytosis is the process by which large molecules are transported out of the cell.

Large polar molecules like glucose and ions such as sodium and potassium are not permeable through the cell membrane. These molecules require specific transport proteins or channels to facilitate their movement across the membrane.
Does facilitated diffusion require energy for the movement of molecules across the cell membrane?
No, facilitated diffusion does not require energy for the movement of molecules across the cell membrane.
Does passive transport require ATP for the movement of molecules across the cell membrane?
No, passive transport does not require ATP for the movement of molecules across the cell membrane.
Are masses of cells full of pores?
Cells are not full of pores. Cell membranes have specific transport proteins that allow certain substances to enter or exit the cell. These transport proteins regulate the movement of molecules in and out of the cell, preventing large molecules from freely flowing in and out of the cell.
What describes the movement of water molecules in and out of a cell?
osmosis
