Oxygen is a small molecule that can easily diffuse across cell membranes, including the membranes of red blood cells. This passive diffusion process is faster and more efficient than active transport for molecules like oxygen that are able to freely move across cell membranes.
What else can I help you with?
A molecule that can diffuse freely through a phospholipid bilayer is probably?
By Passive transport i can onlythink of glucose, but by active transport material like water, carbon dioxide, amino acids, sodium and potasium and of course oxygen! :)
What effect does lack of oxygen have on active transport?
Lack of oxygen impairs aerobic metabolism, which is needed to produce the ATP required for active transport processes. This can lead to a decrease in the efficiency and effectiveness of active transport mechanisms, ultimately affecting the ability of cells to maintain ion gradients and transport molecules across membranes.
Does diffusion and active transport use oxygen?
Diffusion does not require energy and can occur without the need for oxygen. Active transport, on the other hand, requires energy in the form of ATP and does not directly involve the use of oxygen, although oxygen is essential for producing ATP through cellular respiration.
Why does oxygen diffuse into cell?
Oxygen diffuses into cells due to differences in oxygen concentration between the environment and the cell. Cells consume oxygen during cellular respiration to produce energy, creating a concentration gradient that drives oxygen diffusion into the cell. Oxygen then binds to hemoglobin in red blood cells for transport to tissues throughout the body.
What part of the lung do oxygen molecules diffuse across into the bloodstream?
Oxygen molecules diffuse across the alveolar membrane in the lungs into the bloodstream. This is where gas exchange occurs, with oxygen moving from the alveoli into capillaries surrounding the alveoli.
What structure does oxygen diffuse through that a sodium ion may need active transport?
A semipermeable membrane
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.
What is a process that releases energy when oxygen is insufficent?
Active Transport..........

What structure does oxygen diffuses through but a sodium ion may need active transport?
Oxygen can diffuse through the cell membrane, which is selectively permeable to small non-polar molecules. On the other hand, sodium ions are charged and larger, so they typically require active transport mechanisms such as protein pumps to move across the cell membrane.
What effect does lack of oxygen have on active transport?
Lack of oxygen impairs aerobic metabolism, which is needed to produce the ATP required for active transport processes. This can lead to a decrease in the efficiency and effectiveness of active transport mechanisms, ultimately affecting the ability of cells to maintain ion gradients and transport molecules across membranes.
Does active transport use oxygen?
Active transport (or active uptake, as we learnt it ) is moving against the concentration gradient. This requires energy which is why the oxygen is needed (the oxygen producing energy through respiration). It is affected by the concentration of oxygen because the more oxygen, the more energy produced, the faster the process occurs. Diffusion is not affected by the concentration of oxygen because it does not require energy to occur.
What is an example is active transport?
An example of active transport is sugar molecules going into a cell. It cannot pass right through like water and oxygen so it uses active transport.Diffusion
Is an example of active transport?

Is oxygen lipid soluble?
No, oxygen is not lipid soluble. It is a small, nonpolar molecule that can diffuse easily across cell membranes without the need for specific transport mechanisms.
The statement below refers to a structure of the cell oxygen diffuse through this structure but sodium ion may need active transport which structure is this statement most likely referring to?
a semipermeable membrane
