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
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.
Give the 4 factors affecting substance transport?
-structure and composition of the membrane -sizes of molecules -movement of molecules -internal and external condition
What is the movement of water across a membrane?
Active transport
What is the movement of water across the membrane?
Active transport
What is a 15 letter word for molecular movement?
active transport
Does facilitated transport require energy for the movement of molecules across the cell membrane?
Yes, facilitated transport does require energy for the movement of molecules across the cell membrane.
What type of molecular movement is it if movement of molecules is against the concentration gradient from low to high through protein pumps?
Active transport is the type of molecular movement when molecules move against the concentration gradient from low to high through protein pumps. This process requires energy input, typically in the form of ATP, to pump molecules across the cell membrane.
Does facilitated diffusion require a transport protein for the movement of molecules across the cell membrane?
Yes, facilitated diffusion does require a transport protein for the movement of molecules across the cell membrane.
What is the name of the membrane that allows the movement of water and substances to move through the process of active transport and passive transport?
The cell membrane, also known as the plasma membrane, is responsible for regulating the movement of water and substances through processes like active transport and passive transport. It acts as a selectively permeable barrier, allowing certain molecules to pass through while blocking others.
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 is the transport of water across the cell membrane called?
Movement of water across a membrane is called OSMOSIS.
