Movement of molecules across a membrane to an area of higher concentration?
This process is called active transport. It requires energy in the form of ATP to move molecules against their concentration gradient. Examples include the sodium-potassium pump in animal cells and the proton pump in plant cells.
Active transport counters the process of diffusion?
Yes, active transport is a process in which cells use energy to move molecules against their concentration gradient, whereas diffusion is a passive process where molecules move from an area of high concentration to an area of low concentration. Active transport allows cells to transport molecules against their concentration gradient, which is opposite to the direction of diffusion.
If plant cells are immersed in distilled water the resulting movement of water into the cells is called?
The movement of water into plant cells when they are immersed in distilled water is called osmosis. Osmosis is the diffusion of water molecules across a selectively permeable membrane from an area of higher water concentration to an area of lower water concentration.
How do plants move water in and out of their cells?
Plants move water through their cells using a process called transpiration, where water evaporates from the leaves and creates a negative pressure that pulls water up from the roots. Water is brought into the cells through a process called osmosis, where water molecules move from an area of low concentration (soil) to an area of high concentration (root cells).
What process drives molecules across a membrane against a concentration gradient?
Active transport is the process that drives molecules across a membrane against a concentration gradient, requiring energy input in the form of ATP. This process allows cells to accumulate substances they need in higher concentrations than their surroundings.
How does oxygen get out of the leaf cells and back into the air outside the plant?
Oxygen exits leaf cells through small openings called stomata. These stomata are located on the underside of the leaf and open to release oxygen into the surrounding air.
What diffusion is lower concentration to a higher concentration?
This process is called active transport, where cells use energy to move molecules against their concentration gradient, from an area of lower concentration to a higher concentration. This mechanism allows cells to maintain specific intracellular concentrations of certain molecules that are different from their surroundings.
What is the process by which molecules such as glucose are moved into cells along their concentration gradient with the help of membrane bound carrier proteins called?
This process is called facilitated diffusion, in which carrier proteins assist in the movement of molecules across the cell membrane from an area of higher concentration to an area of lower concentration, without requiring energy input from the cell. The carrier proteins undergo conformational changes to transport the molecules across the membrane.
Movement of molecules across a membrane to an area of higher concentration?
This process is called active transport. It requires energy in the form of ATP to move molecules against their concentration gradient. Examples include the sodium-potassium pump in animal cells and the proton pump in plant cells.
Simple molecules are further broken down in cells in a process called?
Simple molecules are further broken down in cells in a process called catabolism.

Yes, active transport is a process in which cells use energy to move molecules against their concentration gradient, whereas diffusion is a passive process where molecules move from an area of high concentration to an area of low concentration.

The process by which molecules move from an area of higher concentration to an area of lower concentration?
This process is called diffusion, where molecules move down their concentration gradient to achieve equilibrium. It does not require energy input and is driven by the random motion of particles. Diffusion is a key mechanism for various biological processes such as gas exchange in the lungs and nutrient uptake in cells.
What process drives molecules across a membrane against a concentration gradient?
Active transport is the process that drives molecules across a membrane against a concentration gradient, requiring energy input in the form of ATP. This process allows cells to accumulate substances they need in higher concentrations than their surroundings.
During the process of diffusion what is occurring?
Diffusion is the movement of particles from an area of high concentration to an area of low concentration. This happens naturally as particles move randomly and collide with each other, eventually distributing themselves evenly throughout the space.
What is large molecules to small molecules called?
The process of breaking down large molecules into smaller molecules is called catabolism. This process releases energy that cells can use for various functions.
