Where does the energy needed for the movement of molecules in diffusion and osmosis come from quizlet?

(2.3) Where does the energy needed for the movement of molecules in diffusion and osmosis come from? The energy comes from thermal energy.

Where does energy in diffusion come from?

The kinetic energy of the molecules results in random motion, causing diffusion. In simple diffusion, this process proceeds without the aid of a transport protein. it is the random motion of the molecules that causes them to move from an area of high concentration to an area with a lower concentration.

Where does osmosis get energy from?

Osmosis is a selective diffusion process driven by the internal energy of the solvent molecules. It is convenient to express the available energy per unit volume in terms of “osmotic pressure”. It is customary to express this tendency toward solvent transport in pressure units relative to the pure solvent.

Where does the energy in molecules come from?

Beginning with energy sources obtained from their environment in the form of sunlight and organic food molecules, eukaryotic cells make energy-rich molecules like ATP and NADH via energy pathways including photosynthesis, glycolysis, the citric acid cycle, and oxidative phosphorylation.

Are you actually observing molecular movement?

Are you actually observing molecular movement? No, as water has KE, not particles. Random movement is KE, directional is due to pressure differences.

How is osmosis related to diffusion?

Osmosis only allows solvent molecules to move freely, but diffusion allows both solvent and solute molecules to move freely. Osmosis happens when molecules move from higher to lower concentrations, but diffusion happens when it is reversed.

Is energy needed in osmosis?

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.

Is energy involved in osmosis and diffusion?

Diffusion and osmosis are both examples of passive transport which do not require energy.

Does osmosis require energy?

What is the relationship between molecular motion and energy?

the relationship between molecular motion and kinetic energy is that the faster the molcules are moving, the higher the kinetic energy is.

What is molecule movement?

Molecular motion is defined as the movement of constituent particles or molecules in a certain direction. The molecular motions are affected by heat and temperature. This is because the temperature is the measurement of the average kinetic energy of the molecules and represents the motion of molecules.

How is osmosis related to diffusion quizlet?

Osmosis is related to diffusion because it is a type of diffusion, meaning that it is the movement of molecules to an area of high concentration to an area of lower concentration. Osmosis pertains specifically to the movement of water molecules though.
