Q:

Why is diffusion important?

A:

Quick Answer

Diffusion is important as it allows cells to get oxygen and nutrients for survival. In addition, it plays a role in cell signaling, which mediates organism life processes.

Full Answer

Diffusion is important for several reasons:

  • It promotes cellular respiration - In order for cells to survive, they need oxygen. Oxygen moves from areas of high concentration to low concentration, allowing the cell to respirate.
  • Nutrients pass through to cells - Cells need nutrients, such as glucose, to survive. Diffusion allows these nutrients to pass through to cells according to their needs.
  • It makes taking medication simpler - When people take medication in the form of a capsule, diffusion encourages the substance to move from the capsule and into the digestive system. Once there, diffusion allows it to move into the bloodstream. Without diffusion, people would have to rely on inconvenient methods of medication, like IVs. It also allows for innovative ways to medicate, like transdermal patches.
  • Diffusion in the form of active transport encourages cell signaling - In order for cells to function, they need signaling proteins. Not all proteins can move across the cell membrane via passive diffusion, but they can via active diffusion. When adenosine triphosphate donates a phosphate group to this practice, proteins can enter the cell.
  • It makes the nervous system work - Without diffusion in the form of the sodium-potassium pump, nerve cells would not innovate.

    Why do diabetics get so sleepy when their sugar is high?

    A:

    Diabetics get sleepy when their blood sugar is high because the thickening of the blood from excess sugar slows circulation, keeping oxygen and essential nutrients from entering the cells, according to Diabetes Self-Management. High blood glucose levels can also cause fatigue when sugar causes inflammation of the blood vessels.

    Why is water important to cells?

    A:

    Water is important to cells because without it they would not be able to remove waste, bring in nutrients or transport oxygen. The body is a very intricate system where many parts rely on each other. Without the cells being able to perform or move oxygen around the body, death would be quick to follow the loss of the water.

    What do cells need to survive?

    A:

    In order for cells to survive, they require nutrients in the form of glucose and minerals plus oxygen. Additionally, they need to dispose of waste products. Cells also rely on their organelles and diffusion for survival.

  • Q:

    What are some facts about diffusion?

    A:

    The most important fact about diffusion is that it is passive. It occurs as a result of the random movement of molecules, and no energy is transferred as it takes place.
