How can oxygen cross the membrane?
By the process of simple diffusion.
Where in the eukaryote membrane do simple diffusion take place?
Cytoplasm
How simple diffusion can be distinguished from facilitated diffusion?
Simple diffusion does not involve the use of transport proteins and relies on the concentration gradient of molecules for movement across the membrane. Facilitated diffusion, on the other hand, requires specific transport proteins to help facilitate the movement of molecules across the membrane, often against their concentration gradient.
What are the two types of possive transport?
The two types of passive transport are simple diffusion and facilitated diffusion. Simple diffusion involves the movement of molecules across a cell membrane without the need for a specific protein. Facilitated diffusion, on the other hand, requires the assistance of specific transport proteins to move molecules across the membrane.
What is the diffusion of water across a semipermeable memberane?
Diffusion of water across a semipermeable membrane is a type of simple diffusion given the special name of osmosis.
Moves small or lipid-soluble solutes through the membrane?
simple diffusion
What moves small or lipid soluble solutes through the membrane?
Small or lipid soluble solutes can pass through the cell membrane via simple diffusion. This process occurs without the need for energy or specific transport proteins, as these solutes can move freely through the lipid bilayer of the membrane due to their size or lipid solubility.
How can oxygen cross the membrane?
By the process of simple diffusion.
The process where a nonpolar molecule can just passively get across a membrane is called?
facilitated diffusion
How is faciliated transport similar to simple diffusion?
Facilitated and simple diffusion both transport solutes along a concentration gradient and neither processes require any ATP expenditure.
What happens in simple diffusion?
In simple diffusion, a substance passes through a membrane without any outside intermediary. The rate of diffusion is based on the force exerted..
Where in the eukaryote membrane do simple diffusion take place?
Cytoplasm
What is the difference between facilitated diffusion and simple diffusion in terms of the mechanisms by which molecules move across a cell membrane?
Facilitated diffusion involves the movement of molecules across a cell membrane with the help of specific proteins, while simple diffusion does not require any proteins and relies on the molecules moving freely through the membrane.
When molecules such as oxygen are moved into Cells along their concentration gradient directly through the Cell membrane - this is called?
Trans-membrane diffusion.
The process by which simple sugar passes through a membrane is called?
diffusion
What is the diffusion of water across the semipermeable?
Diffusion of water across a semipermeable membrane is a type of simple diffusion given the special name of osmosis.
