What else can I help you with?
What substance will diffuse through a membrane?
Substances that are small, nonpolar, and uncharged will diffuse through a membrane easily. This includes gases like oxygen and carbon dioxide, as well as small lipophilic molecules. Larger or charged molecules may require assistance from transport proteins to cross the membrane.
How does oxygen get into a unicellular organism?
Oxygen can diffuse into a unicellular organism through its cell membrane. The organism utilizes this oxygen for cellular respiration to produce energy.
What particles can diffuse directly through the lipid bi-layer?
As the bilayer contains hydrophobic fatty acid tails, water-soluble molecules cannot diffuse directly through. However, lipid soluble molecules such as oxygen can diffuse directly through. Overall, for a molecule to be able to diffuse directly through it must be lipid-soluble, relatively small and non-polar.
What substances diffuse into and what diffusen out of cells?
The substances flow from high concentration to low concentration through channels found in the cell membrane. Basically like a bridge.
What is an example of molecules that diffuses into a cell?
water
In an earthworm is a respiratory system evident?
Earthworms breath through their skin, earthworms diffuse oxygen through a network of thin-walled capillaries which are found just under the skin.
In animals that carry out respiration though the skin the skin must always be?
In animals that rely on skin for respiration, the skin must be moist. This moisture helps facilitate gas exchange by allowing oxygen and carbon dioxide to diffuse through the skin. Dry skin would impede this process.
Does oxygen diffuse through a semipermable membrane?
yes
What particles could diffuse easily through a cell membrane sodium and oxygen?
Oxygen (O2)
How do you resive oxygen and remove carbon dioxide?
Oxygen and carbon dioxide are moved to and from body tissues via the circulatory system. These materials diffuse through the cell membrane, and then diffuse through the capillary wall into or out of the bloodstream.
Air sacs in the lungs through which oxygen and carbon dioxide diffuse into and out of the blood are the?
alveoli
What are Air sacs in the lungs through which oxygen and carbon dioxide diffuse into and out of the blood are?
The humorus
What are the air sacs in the lungs through which oxygen and carbon dioxide diffuse into the blood?
AVEVOLIS
What substance will diffuse through a membrane?
Substances that are small, nonpolar, and uncharged will diffuse through a membrane easily. This includes gases like oxygen and carbon dioxide, as well as small lipophilic molecules. Larger or charged molecules may require assistance from transport proteins to cross the membrane.
Do reptiles obtain oxygen through their skin?
No, its just some reptiles that obtain oxygen through their skin. Many of them breath through their lungs.
How does oxygen get into a unicellular organism?
Oxygen can diffuse into a unicellular organism through its cell membrane. The organism utilizes this oxygen for cellular respiration to produce energy.
What two gases diffuse into or out of cells?
Oxygen and carbon dioxide diffuse into and out of cells through the cell membrane. Oxygen is required for cellular respiration while carbon dioxide is a waste product that needs to be removed from the cell.
