How is active transport different from simple diffusion? Both active transport and simple diffusion transport molecules against the concentration gradient. In active transport, molecules are moved down the concentration gradient; on the B contrary, molecules to be transported in simple diffusion are moved against the concentration gradient. In active transport, molecules are transported with the aid of transport proteins; on the © other hand, molecules to be transported in simple diffusion do not need transport proteins. In active transport, molecules that are transported does not need metabolic energy; in contrast, molecules transported in simple diffusion need metabolic energy.

TONICITY DRAGTHE WORDS INTO THE BLANK SPACES BELOW TO ACCURATELY COMPLETE THE PARAGRAPH decreases Hypertonic increases key: Hypotonic solute particle • cell membrane cell wall solute in all solutions, the solvent is H20 solvent A В Solution B is to solution A. This is because solution B has a greater concentration of in it than does solution A. Solution C has no solutes dissolved in it, therefore it is to both Solutions A and B. As the relative concentration of solutes in two solutions increases, of necessity the relative concentration of water in the same two solutions Solution A has a lower concentration of than does Solution C; Solution A is also hypertonic to Sol tion C.
In your words explain passive transport by osmosis using isotonic, hypertonic, and hypotonic in both animal and plant cell.
Which of the following best describes a hypotonic solution? O There is a higher concentration of solute outside the cell than inside the cell There is a lower concentration of solute outside the cell than inside the cell The solute concentration both inside and outside the cell is equal O Through osmosis, water will enter the cell causing it to swell Which of the following is true regarding bulk transport? ATP is required to pump molecules against the concentration gradient Bulk transport is an example of passive transport Transport of large quantities of materials ATP changes the shape of a protein channel during active transport
In facilitated diffusion, what is the role of the transport protein? > View Available Hint(s) O Transport proteins allow solutes to move passively down their concentration gradient across the membrane. O Transport proteins provide the energy for diffusion of the solute. O Transport proteins provide a low-resistance channel for water molecules to cross the membrane. O Transport proteins provide a protein site for ATP hydrolysis, which facilitates the movement of a solute across a membrane. Transport proteins organize the phospholipids to allow the solute to cross the membrane.
Osmosis Practice Activity Osmosis is the diffusion of water from an area of high concentration to an area of low concentration. Only water moves in osmosis! The diagrams below show the concentration of water and salt inside the cell and the concentration of water and salt surrounding the cell. Complete the sentences below by comparing the concentration of the water inside the cell and the concentration outside the cell. 1. a. Water will flow the cell, out of the cell, in both directions).
