What else can I help you with?
What are the processes involved in moving substances across the cell membrane?
Diffusion
When molecules are moving back and forth across the membrane will they ever stop moving?
Yes, in an isotonic solution the movement of molecules across the membrane will stop.
Are carrier proteins active or passive transport?
Carrier proteins facilitate active transport by moving molecules or ions across a cell membrane against their concentration gradient. They require energy in the form of ATP to transport substances across the membrane.
What is passive transpot?
Passive transport is the movement of substances across a cell membrane without the use of energy. It occurs along a concentration gradient, with substances moving from an area of high concentration to an area of low concentration. Examples include diffusion and facilitated diffusion.
When will water stopping across a membrane?
When will water stop moving across a membrane when the water concentration is equal on both sides.
How do the called the Process of moving substances over the cell membrane?
The process of moving substances across the cell membrane is called "transport." This can occur through various mechanisms, including passive transport (such as diffusion and osmosis) and active transport, which requires energy to move substances against their concentration gradient. Additionally, facilitated diffusion involves specific transport proteins to help substances cross the membrane. Together, these processes maintain the cell's internal environment and enable communication and nutrient uptake.
Is a special type of diffusion that involves moving across a cell membrane?
osmosis is a special type of diffusion that involves water moving across a cell membrane hopefuly this helped :)
How is facilitated diffusion similar to active transport in terms of their mechanisms of moving substances across the cell membrane?
Facilitated diffusion and active transport are similar in that they both involve the movement of substances across the cell membrane with the help of specific proteins. However, facilitated diffusion does not require energy, while active transport does require energy in the form of ATP to move substances against their concentration gradient.
Is water moving across the cell membrane osmosis?
yes
How is active transport similar to facilitated diffusion in terms of their mechanisms of moving substances across the cell membrane?
Active transport and facilitated diffusion are both mechanisms used by cells to move substances across the cell membrane. Both processes require the use of specific proteins embedded in the cell membrane to facilitate the movement of substances. However, the key difference between the two is that active transport requires energy input from the cell to move substances against their concentration gradient, while facilitated diffusion does not require energy and moves substances down their concentration gradient.
When will water and solutes stop moving across a membrane?
Particles in a given medium stop moving across the membrane during diffusion when a state of equilibrium is reached, that is when the number of particles on either side of the membrane equalizes.
When will water stop moving across membranes?
When will water stop moving across a membrane when the water concentration is equal on both sides.
