Active transport is defined as the movement of molecules across the cell membrane by using cellular energy. Passive transport is the movement of molecules across the membrane without the use of ATP. No cellular energy is required in this process.
the concentration of water determines the direction in which molecules will move during osmosis. the concentration inside and outside of the cell are equal. Hypotonic. the concentration of solute is lower outside the cell, therefore the concentration of water id high. Click to see full answer.
Water will move in the direction where there is a high concentration of solute (and hence a lower concentration of water.
Substances move into or out of the cell and enzymes are catalysts contributing to cell metabolism. The idea of concentrations and the gradients within them is important when understanding the movement of particles or molecules across cell membranes. When sucrose is dissolved in water, the solute is sucrose and water is the solvent.

When the concentration of water outside a cell is the same as the concentration of water inside the cell?
Therefore, water will diffuse down its concentration gradient, crossing the membrane to the side where it is less concentrated. This diffusion of water through the membrane—osmosis—will continue until the concentration gradient of water goes to zero. Osmosis proceeds constantly in living systems.
When the concentration of molecules is equal inside and outside the cell what direction does water move?
The net movement of water (osmosis) is in the direction of increased solute concentrations. An easy way to visualize this rule is simply that the net water movement is from an area of high water concentration (little dissolved solute) to an area of low water concentration (high levels of solute).
What is the direction of water movement in a cell?
Osmosis: This is the hydrostatic force acting to equalize the concentration of water on both sides of the membrane that is impermeable to substances dissolved in that water. Water will move along its concentration gradient.
What is the difference between active transport and passive transport across the plasma membrane?
Active transport moves molecules and ions from lower concentration to higher concentration with the help of energy in the form of ATP. On the other hand, passive transport moves molecules and ions from a higher concentration to lower concentration without any energy.
What is the difference between active and passive membrane transport quizlet?
Active transport the molecules move from a lower concentration to a higher concentration. Passive transport the molecules move from a higher concentration to the lower concentration.
What is active transport differentiate between active and passive transport?
Examples of active transport include a sodium pump, glucose selection in the intestines, and the uptake of mineral ions by plant roots. Passive transport occurs in the kidneys and the liver, and in the alveoli of the lungs when they exchange oxygen and carbon dioxide.
What is the difference between active and passive transport across the plasma membrane?
Active transport is defined as the movement of molecules across the cell membrane by using cellular energy. Passive transport is the movement of molecules across the membrane without the use of ATP. No cellular energy is required in this process.
What is the difference between passive transport and active transport quizlet?
Passive transport doesn’t require energy (ATP), active transport does require energy. Passive transport moves molecules WITH the concentration gradient (high to low), while active transport moves molecules AGAINST the concentration gradient (Low to High).

What Is Cell Diffusion? – Reference.com
Cellular diffusion is the process that causes molecules to move in and out of a cell. Molecules move from an area of high concentration to an area of low concentration. When there is a higher concentration of molecules outside of a cell, then more molecules enter the cell than leave. When there is a higher concentration of molecules inside of a cell, then more molecules leave the cell than enter.

Movement In And Out Of Cells – IGCSE Biology Notes (2020)
As the water moves out, cells become ’flaccid’. An animal cell can become crenated if too much water is lost. A plant cell can become plasmolysed if too much water is lost. This is when the cytoplasm shrinks due to the loss of water but the cell wall fails to shrink due to its tough structure. The cytoplasm eventually tears away from the …
