Which of the following statement is not true about diffusion?

The correct answer is (c) Rate of diffusion of gases depends on their volume. Rate of diffusion of gases does not depends on their volume. Diffusion is the process of particles moving from highly concentrated region to low concentrated region. … Diffusion is only possible when the matter moves continuously.

Does diffusion require ATP?

Simple diffusion does not require energy: facilitated diffusion requires a source of ATP. Simple diffusion can only move material in the direction of a concentration gradient; facilitated diffusion moves materials with and against a concentration gradient.

Which of the following statements about passive transport is correct?

which of the following statements about passive transport is correct? passive transport permits the solute to move in either direction, but the net movement of the population of solute occurs down the concentration gradient of the molecule. a selectively permeable membrane separates two solutions.

Which of the following statements concerning diffusion and active transport is correct?

Which of the following statements concerning diffusion and active transport is correct? both diffusion and active transport require cell energy. neither diffusion nor active transport requires cell energy. diffusion requires cell energy while active transport does not.

Where does simple diffusion occur?

Simple passive diffusion occurs when small molecules pass through the lipid bilayer of a cell membrane. Facilitated diffusion depends on carrier proteins imbedded in the membrane to allow specific substances to pass through, that might not be able to diffuse through the cell membrane.

Which is required for diffusion to occur?

For diffusion to occur there must be a concentration gradient. The dissimilarity in the amounts of solutes, particles, or molecules between the two regions will cause them to move between the two regions.

Which of the following is correct regarding diffusion?

Diffusion takes place only in gases. Movement of substances takes place from low concentration to high concentration. Movement of substances takes place from high concentration to low concentration.

Which of the following is false in regard to facilitated diffusion?

Which of the following is FALSE in regard to facilitated diffusion? Facilitated diffusion requires the hydrolysis of ATP. A selectively permeable membrane separates two solutions. Water is able to pass through this membrane; however, sucrose (a disaccharide) and glucose (a monosaccharide) cannot pass.

Which of the following statements is correct about passive diffusion quizlet?

Which of the following statements is correct about passive diffusion? It involves movement of molecules down a concentration gradient and may require a transport protein. Which one of the following organisms has a cell wall? pili are used for transfer of DNA and motility.

Which of the following statements is incorrect about osmosis *?

The incorrect statement about osmosis is- i. It occurs only in plants. In osmosis, the diffusion of water molecules takes place from a solution of higher concentration to a solution of lower concentration through a semi-permeable membrane. Thus, a concentration gradient should be present for the osmosis to happen.

Which statements are correct for both diffusion and osmosis?

Both osmosis and diffusion equalize the concentration of two solutions. Both diffusion and osmosis are passive transport processes, which means they do not require any input of extra energy to occur. In both diffusion and osmosis, particles move from an area of higher concentration to one of lower concentration.

Which of the following is incorrect about diffusion molecules move in random fashion?

In diffusion, molecules move in a random fashion, the net result being substances moving from regions of higher concentration to regions of lower concen-tration. Diffusion is a slow process and is not dependent on a living system. … Movement by diffusion is passive as no energy expenditure takes place.

Which of the following statement is correct about osmosis?

Osmosis is a kind of diffusion of solvent molecules through the semipermeable membrane.

Which is wrong about osmosis?

Osmotic pressure is referred to the applied positive pressure , while y osmotic potential is negative.

Which of the following statements are correct to define osmosis?

Option C: Osmosis is the movement of a solvent (water in the living system) from a region of its high concentration (less concentrated solution) to a region of its low concentration (more concentrated solution) across a semipermeable membrane. … Therefore, this is the correct option.
