It is very rapid over long distances. Seawater is hypertonic to cytoplasm in vertebrate cells and in plant cells. 18 Which of the following statements about diffusion is true.

If a red blood cell and a plant cell were placed in seawater what would happen to the two types of cells. Facilitated diffusion allows polar molecules to pass through the phospholipid bilayer C. It is a passive process.

A The rate is independent of temperature. Diffusion of atoms in pure metals is called self-diffusion. Diffusion is the movement of water across a selectively permeable membrane.

Diffusion is rapid over long distances but much slower over short distances. D Diffusion occurs when particles spread from areas where they are less concentrated to areas where they are more concentrated. The rate of diffusion decreases as temperature increases.

The more soluble X is in nonpolar solvents the easier it is for X to diffuse across the membrane. Only water can diffuse across a cell membrane. B Molecular weight of a substance does not affect the rate.

Which of the following statements is true. In facilitated diffusion molecules move from high to low concentration B. Which of the following statements about diffusion is true.

Which are true and which are false. Diffusion regulates which molecules can and cant pass through a plasma membrane. Diffusion describes the concentration gradient in a solutionCONCEPT Diffusion 14.

C The lower the temperature the faster the rate. Read the following statements regarding facilitated diffusion. All transmembrane proteins move molecules into cells D.

If X is water its rate of diffusion across membranes is high. C Only water can diffuse across a cell membrane D Molecules move from areas of high concentration to areas of low concentration. BDiffusion require energy input from the cell.

This mechanism can describe the diffusion of substitutional impurity atoms in a metal. Diffusion may require an input of energy depending on the specific mechanism of diffusion. B Diffusion requires no input of energy into the system.

The rate of facilitated diffusion is directly dependent on the affinity of the solute for the carrier protein. All the above are true statements about diffusion ANSWER. B Diffusion is driven by concentration gradients C Diffusion requires no input of energy into the system.

White matter integrity obtained from Diffusion Tensor Imaging can be correlated with symptoms or cognitive performance. Molecules move from areas of high concentration to areas of low concentration. Which of the following is a true statement of diffusion.

C Membrane lipids diffuse within the plane of the membrane. Which of the following statements is correct regarding net diffusion. EText Concept 73 It always requires integral proteins of the cell membrane.

It occurs when molecules move from a region of lower concentration to a region of higher concentration. The net diffusion of solutes utilizing facilitated diffusion can never be zero. Diffusion is a result of the thermal energy of atoms and molecules.

In diffusion there is a net movement of molecules from areas of higher concentration to areas of lower concentration. Diffusion is only important for animal cells. Diffusion involves the breaking down of dead organelles.

Larger molecules diffuse faster than smaller molecules. Check all that apply Check All That Apply There are always some vacancies present in metals or alloys as equilibrium defects. Diffusion does not require energy and is therefore a form of passive transport.

The smaller the molecular weight of X is the slower its diffusion. Diffusion involves the movement of molecules using transport proteins. 13 Which of the following statements is true.

C Diffusion occurs when particles spread from areas where they are less concentrated to areas where they are more concentrated. Diffusion occurs when particles spread from areas where they are less concentrated to areas where they are more concentrated. Which of the following statements about diffusion of substance X across a plasma membrane is true.

Group of answer choices. The rate of facilitated diffusion is directly dependent on the concentration gradient of the solute across the. B It requires an expenditure of energy by the cell.

It is faster than diffusion by a vacancy mechanism in the same metal at the same temperature. D The greater the concentration gradient the faster the rate. A Diffusion is a result of the thermal energy of atoms and molecules.

Which of the following statements about diffusion is true. Concentration gradient of a molecule is not necessary to transport it across a biological membrane in the process of. 45 Which of the following statements regarding diffusion is false.

White matter integrity obtained from Diffusion Tensor Imaging can provide a measure of functional ability. Its a passive process. Diffusion occurs even after equilibrium is reached and no net change is apparent.

C It is an active process in which molecules move from a region of lower concentration to a region of higher concentration. A Diffusion is only important for animal cells. It requires expenditure of energy by the cell.

Which of the following statements about diffusion is true. It requires integral proteins in the cell membrane. An example of this mechanism is the diffusion of carbon in iron.

D Membrane lipids frequently flip-flop between one monolayer and the other. Which of the following statements about facilitated diffusion is are true. None of the above ie.

It is a passive process in which molecules move from a region of higher concentration to a region of. Diffusion involves the movement of molecules in the cytoplasm. As the temperature of the solid increases fewer vacancies will be present and the diffusion rate will decrease.

Vacancies hinder diffusion by substitution. Molecules move from an area of higher concentration to an area of lower concentration.
