Which of the following would not be facilitated diffusion?
marusya05 [52]

Answer:

A. A water molecule passes through a semi permeable membrane

Explanation:

Facilitated diffusion is the diffusion of a molecule without any assistance from a protein or protein channel.

In facilitated diffusion, a molecule will diffuse by itself through a semi permeable membrane, such as the cell membrane.

Answer choices B, C, and D are incorrect because they are all examples of facilitated diffusion. The molecules required assistance from a protein.

Answer choice A is correct because the water molecule was able to pass through by itself.

So, the correct answer is A. A water molecule passes through a semi permeable membrane

FrozenT [24]

The given question is incomplete, the complete question is:

Steroids are cholesterol based hormones. Nerve Growth Factor (NGF) is a water-soluble signaling molecule. Both have essential roles in cell function and organismal development. How are they received by the cell? A) Receptors for steroids are located in the plasma membrane and receptors for NGF are located in the cytosol. B) Receptors for steroids and NGF are located in the plasma membrane, C) Receptors for steroids and NGF are located in the cytosol, D) Receptors for steroids are located in the cytosol and receptors for NGF are located in the plasma membrane

Answer:

The correct answer is option D, that is, for steroids the receptors are situated in the cytosol and for NGF the receptors are situated in the plasma membrane.

Explanation:

NGF or the nerve growth factor is the water-soluble signaling molecule, and steroids are the cholesterol-based hormones. Both possess important functions in cell activities and the development of organisms. They are attained by the cells with the help of receptors for steroids situated in the cytosol, and the NGF receptors situated in the plasma membrane.

The plasma membrane permits the hydrophobic molecules, that is, water-insoluble molecules to pass through it. The water-insoluble molecules are the steroids, therefore, it can easily go through the plasma membrane and thus possess receptors within the cytosol. On the other hand, the water-soluble or the hydrophilic molecules are the NGF, they fail to pass through the plasma membrane, and thus, possess receptors on the plasma membrane.
