What else can I help you with?
What is the process When proteins help molecules move across the membrane is called?
when proteins help molecules move across the membrane, it it called Facilitated Diffusion
Which process requires energy to bring molecules across the cell membrane?
Active transport requires energy to move molecules across the cell membrane against their concentration gradient. This process is carried out by specific proteins called pumps that utilize cellular energy in the form of ATP to transport molecules.
What kinds of molecules freely diffuse across a semipermeable membrane?
Water molecules freely diffuse across a semipermeable membrane.
What is the process in which molecules move across the cell membrane from a region of low concentration to a region of high concentration?
Active Transport - the process of moving particles across a cell membrane against a concentration gradient <- right one
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.
Is the movement of molecules across a membrane down the concentration gradient a passive or active process?
The movement of molecules across a membrane down the concentration gradient is a passive process.
What does a carrier protein do in the process of transporting molecules across a cell membrane?
A carrier protein helps transport molecules across a cell membrane by binding to specific molecules and changing shape to move them across the membrane.
What is the process When proteins help molecules move across the membrane is called?
when proteins help molecules move across the membrane, it it called Facilitated Diffusion
Is diffusion of molecules across the cell membrane the most complex type of active?
Diffusion of molecules across the cell membrane is actually a passive process, not active. Active transport, which requires energy in the form of ATP, is a more complex process as it moves molecules against their concentration gradient.
How do carrier proteins facilitate the passive transport of molecules across a membrane?
Carrier proteins facilitate the passive transport of molecules across a membrane by binding to specific molecules on one side of the membrane and changing shape to transport the molecules across to the other side. This process does not require energy and is driven by the concentration gradient of the molecules.
What process do water molecules cross the cell membrane?
Water molecules cross the cell membrane through a process called osmosis, which is driven by the concentration gradient of water inside and outside the cell. Aquaporin proteins on the cell membrane facilitate the movement of water molecules into and out of the cell.
How do you transport proteins in a cell make it easier for certain molecules to diffuse across a membrane?
Proteins in the cell membrane can act as transporters or channels, aiding in the facilitated diffusion of specific molecules across the membrane. These proteins provide a passageway for the molecules to move across the membrane by utilizing their specific structure and function. This process helps regulate the movement of molecules in and out of the cell.
Which process requires energy to bring molecules across the cell membrane?
Active transport requires energy to move molecules across the cell membrane against their concentration gradient. This process is carried out by specific proteins called pumps that utilize cellular energy in the form of ATP to transport molecules.
Process when large molecules food and other substances are packaged and moved across the membrane?
bulk transport
What kinds of molecules freely diffuse across a semipermeable membrane?
Water molecules freely diffuse across a semipermeable membrane.
How does active transport work to move molecules across the cell membrane?
Active transport is a process in which cells use energy to move molecules across the cell membrane against their concentration gradient. This is done by using specialized proteins called transporters that pump the molecules across the membrane. The energy required for this process is usually provided by ATP, the cell's energy currency. This allows the cell to maintain the proper balance of molecules inside and outside the cell.
What is the process in which molecules move across the cell membrane from a region of low concentration to a region of high concentration?
Active Transport - the process of moving particles across a cell membrane against a concentration gradient <- right one
