Alcohol primarily crosses cell membranes through passive diffusion. Due to its small size and hydrophobic nature, ethanol can easily diffuse through the phospholipid bilayer of cell membranes without the need for transport proteins. This allows alcohol to rapidly enter cells and affect various biological processes.
What else can I help you with?
What transport may need to use energy to pass through cell membrane?
active transport
What is it called when sugars pass across the membrane that requires the use of energy?
active transport
How do you use passive transport in a sentence?
Passive transport is a process in cells where substances move across the cell membrane without requiring energy input. An example of passive transport is the movement of oxygen and carbon dioxide across the cell membrane through simple diffusion.
What ways of moving molecules across a membrane requires energy?
Active transport requires energy to move molecules across a membrane against their concentration gradient. This process is facilitated by specific carrier proteins embedded in the membrane that use energy, usually in the form of ATP, to transport molecules.
What is this method of molecular transport is called?
Molecular Transport (in cells) is the movement of materials across a cell membrane. The two kinds of Molecular Transport used in organisms are Active Transport and Passive Transport. Active Transport- materials move across the plasma membrane with the use of energy (like Adenosine Triphosphate) Passive Transport- materials move accross the plasma membrane without the use of energy
What transport may need to use energy to pass through cell membrane?
active transport
What is it called when sugars pass across the membrane that requires the use of energy?
active transport
What is it called when the movement of materials through a cell membrane without using the cells energy?
Passive transport does not use energy to pass through a cell membrane. active transport uses energy to pass through a cell membrane.
What requires the use of the energy and the help of transport proteins to move a molecule across a cell membrane?
Active transport
What regulates the rate of passive transport?
The rate of passive transport is regulated by factors such as the concentration gradient of the solute across the membrane, the surface area available for transport, the permeability of the membrane to the solute, and the temperature of the system. These factors affect the movement of molecules across the membrane without the use of energy.

In which membrane is the electron transport chain located?
The outer membrane is where the electron transport chain is located.
Why do cells need to use to use transport protein to function?
Some molecules are too large to pass through the cell membrane without transport proteins.
Which type of membrane transport process uses ATP as a source of energy?
Active transport processes use ATP as a source of energy to move molecules against their concentration gradient across a cell membrane. This process requires specific transport proteins, such as ion pumps, to actively transport molecules across the membrane.
