What else can I help you with?
Is this correct no energy is required for the movement of water molecules across the cell membrane?
No, energy is required for the movement of water molecules across the cell membrane. This process is known as osmosis, where water moves from an area of low solute concentration to an area of high solute concentration, requiring energy to overcome the concentration gradient.
Are energy is required for a variety of life processes including?
Growth and reproduction, movement, and transport of certain materials across the cell membrane
What motion of particles across a membrane requires energy?
Movement across a membrane that does require energy is called active transport.
Where do nutrients enter the cell?
Nutrients enter the cell through the cell membrane via the process of active or passive transport. They can diffuse across the membrane or be actively transported by protein channels or carriers. Once inside the cell, nutrients are used for various cellular processes such as energy production and growth.
Active transprort occurs when someting is used to move substances through a membrane?
Active transport is a process that requires energy to move molecules across a cell membrane against their concentration gradient. This process involves specific transport proteins that act as pumps to move molecules such as ions or other nutrients against the concentration gradient. ATP is typically required as an energy source for active transport to occur.
What required the use of energy to move a molecule across a cell membrane?
Active transport
Is this correct no energy is required for the movement of water molecules across the cell membrane?
No, energy is required for the movement of water molecules across the cell membrane. This process is known as osmosis, where water moves from an area of low solute concentration to an area of high solute concentration, requiring energy to overcome the concentration gradient.
How are the 3 passive transports different?
Simple diffusion - High concentration to low concentration, no energy required osmosis - Movement of water across a membrane, no energy required facilitated diffusion - Movement of substances, protein's are used to help move the substances across the membrane. There are very basic summaries of each.
Why isn't energy required for the passenger molecule to be carried across the cell membrane by the carrier molecule?
it is carring substances both into and out of the cells.

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 facilitated diffusion require energy for the transportation of molecules across the cell membrane?
Facilitated diffusion does not require energy for the transportation of molecules across the cell membrane.
Does facilitated diffusion require energy to transport molecules across the cell membrane?
Facilitated diffusion does not require energy to transport molecules across the cell membrane.
What is passive transportation of cells?
energy is not required for movement across membrane to occcur. molecules move from an area of high concentration to area of low conccentration
What uses a protein to move a molecule across a membrane without energy?
Facilitated diffusion uses proteins to move a molecule across the cell membrane without energy.
