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.
What particles could diffuse easily through a cell membrane sodium and oxygen?
Oxygen (O2)
How do you use diffuse in sentence?
Oxygen molecules diffuse across the membrane.
The layers through which the respiratory gases diffuse are known as the?
The layers through which respiratory gases diffuse are known as the respiratory membrane. This membrane consists of the alveolar epithelium, basement membrane, and capillary endothelium. The exchange of oxygen and carbon dioxide occurs through this membrane during respiration.
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.
What structure does oxygen diffuse through that a sodium ion may need active transport?
A semipermeable 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.
Can oxygen diffuse across a cell membrane?
No, oxygen cannot directly diffuse across a cell membrane. Instead, it crosses the cell membrane with the help of specific transport proteins, such as aquaporins and oxygen channels. These proteins facilitate the movement of oxygen from areas of high concentration to low concentration.
Which particles can diffuse easily througn a cell membrane?
Oxygen
What is an accurate summary of chemiosmosis?
Oxygen diffuse down their concentration gradient out of the stoma into the grana through ion channels in the membrane.
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.
Why can oxygen diffuse across a cell membrane but a protein can't?
Oxygen is a small, non-polar molecule that can passively diffuse across the lipid bilayer of a cell membrane. Proteins, on the other hand, are larger and more complex molecules that cannot pass through the hydrophobic core of the membrane. Instead, proteins are transported into or out of cells through specific channels or transporters.
