What is the role of the phospholipid belayer in cellular transport in living cells


Summarize the role of the phospholipid bilayer in cellular transport in living cells. the polar heads and non polar tails create the barrier between the water and other organism aside from something else that is on the other side. movement of substances across the plasma membrane against the concentration gradient.

Hope this helps! <3


"Osmosis and cellular transport" are the ones among the choices given in the question that is a topic in a biology textbook directly related to physics. The correct option among all the options that are given in the question is the second option or option "B". I hope the answer has come to your help.

Cellular transport independent of ATP like osmosis and difussion (Simple and facilitated).

Explanation: The animal affected has a mitochondrial disease that affects its capacity of ATP production, thus, the animal active transport will be afected since require ATP. On the contrary, the animal passive transport will be functional because its independent of ATP, like osmosis which is water transport in favor of concentration gradient and facilitated diffussion of small molecules.

This is because water helps in stabilizing the conformation or structure, flexibility of proteins and their movement or motion.

Explanation: Every protein have a particular conformation at which it functions optimally. A protein's conformation is stabilized largely by weak interactions and these weak interactions occur more favorably in aqueous medium. A given polypeptide chain can assume different conformations. The chemical interactions that stabilize the native conformation include include disulfide bonds, hydrogen bonds, hydrophobic and ionic interactions. Hydrogen bonds and hydrophobic interactions are formed in the presence of water, though they are weak interactions but their cumulative effect in a protein is significant. These weak interactions helps to maintain the conformation of proteins and ultimately their function.

A. Facilitated diffusion is your answer


Osmosis and cellular transport


-Cell transport is movement of materials across cell membranes. Cell transport includes passive and active transport. Passive transport does not require energy whereas active transport requires energy to proceed. Passive transport proceeds through diffusion, facilitated diffusion and osmosis.

-Osmosis is the transport of water through a semipermeable membrane from a region of high concentration to a region of low concentration. Osmosis is driven by the imbalance in water concentration or the concentration gradient.

B. Cellular transport that does not require cellular energy.

for example, osmosis when water moves from a diluted solution to a concentrated one or diffusion where particles move from the higher concetration to the lower one.

C diffusion is the answer

Cellular transport that does not require cellular energy


Passive transport is a cellular transport of substances from a region of high concentration to a region of low concentration without the use of cellular energy. It occurs mainly in both plants and animals.
