can not cause net transport of molecules...

_____ can not cause net transport of molecules from low to high concentration .

Text Solution

AI Generated Solution

**Step-by-Step Solution:** 1. **Understanding Transport Mechanisms**: There are two main types of transport mechanisms in plants: active transport and passive transport. 2. **Active Transport**: This process requires energy (ATP) to move molecules from an area of low concentration to an area of high concentration. Therefore, active transport can cause net transport of molecules from low to high concentration. 3. **Passive Transport**: This process does not require energy. Molecules move from an area of high concentration to an area of low concentration. ...

Read the following statements and choose the correct ones-- (A) Diffusion is a slow process and is dependent on a living system. (B) Diffusion of substances with hydrophilic moiety is facilitated by membrane proteins. (C) Facilitated diffusion causes net transport of molecules from a low to a high concentration. (D) Saturations may be achieved in both facilitated diffusion as well as active transport .

Diffusion of a molecule from low concentration to the high concentration

Knowledge Check

  • Assertion: When a solution is separated from the pure solvent by a semi-permeable membrane, the solvent molecules pass through it from pure solvent side to the solution side. Reason: Diffusion of solvent occurs from a region of high concentration solution to a region of low concentration solution.

    A
    If both assertion and reason are true and reason is the correct explanation of assertion.
    B
    If both assertion and reason are true, but reason is not the correct explanation of assertion.
    C
    If assertion is true, but reason is false.
