Diffusion of nutrients across a cell membrane can be called a form of

Multiple Choice

passive transport.
active transport.
exocytosis.
osmosis.
bulk transpor

Solutions

Expert Solution

The cell membrane is the bilipid layer surrounding the cell that selectively allows substances to pass through it.
- Passive transport is the movement of substances through the cell membrane without use of energy. Diffusion is the movement of nutrients including gases, ions, water molecules to the area of high concentration without use of energy. Diffusion is the form of passive transport. This option is correct.
- The Active transport requires energy for transportation of substances through it. Diffusion does not require energy so this option is incorrect.
- Exocytosis is a form of active transport that releases substances out of the cell. This option is incorrect.

- Osmosis is the movement of solvent particles to the area of high concentration. Diffusion involves movement of solute as well as solvent so this option is incorrect.
- Bulk transport is the movement of substances such as ions back into the membrane with the flow of water. This option is incorrect.

The transport of Potassium across a eukaryotic membrane can happen by either a passive or an...

The transport of Potassium across a eukaryotic membrane can happen by either a passive or an active transport. The active transport is used when Potassium has to move against the concentration gradient that is from a low concentration outside cells to a high concentration inside cells. Ion channels mediate the passive transport and these transport ions from a high concentration to a low concentration. The Potassium channel is very selective for the transport of Potassium. a) Explain how the selectivity...

Transport Across Membranes Trans-membrane transport can occur in 3 different processes. Simple diffusion through an equilibrium channel facilitated diffusion and active transport. To examine these processes we are going to use yeast cells and some simple model systems. Staining with Neutral Red Take a 20ml sample of yeast culture and divide equally into two boiling tubes, Ensure you agitate yeast culture when collecting and dividing to avoid settling. • Next add 5ml NaCO3 solution (1% aq) to each tube • ...

Compared to glycerol (shown), O2 has a higher rate of passive permeability through a cell membrane. Which of these correctly explains why? Choose all that apply. a. The most energetically challenging part of traversing a membrane is passing through the hydrophobic interior. Hydrophobic molecules can more easily do this and so can pass through membranes more easily. b. The most energetically challenging part of traversing a membrane is passing through the polar head groups. Polar molecules can more easily do...
