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! :)
Do hydrogen and oxygen diffuse?
All gases diffuse to a homogenous phase.
Why can oxygen diffuse across a cell membrane but a protein can't?
Oxygen is much smaller than a protein
Why can oxygen diffuse across a cell membrane but a protein can?
Its too large
What is the final acceptor of electrons and hydrogens in the electron transport chain?
oxygen
What structure does oxygen diffuse through that a sodium ion may need active transport?
A semipermeable membrane
What processes can take place in a root hair cell when oxygen is not available?
active transport and osmosis

What is a process that releases energy when oxygen is insufficent?
Active Transport..........
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 characteristics is more likely to make a substance diffuse through the cell membrane?
Size. Actually very few substances are able to diffuse across the menbrane, most must be transported ie facilitated diffusion, active transport, or receptor-mediated endocytosis. Carbon dioxide, oxygen, water, and some lipid substances are able to diffuse across the membrane
Is an example of 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

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
How is oxygen transported in the cell?
by active and passive transport via cell membrane proteins
What causes oxygen from the water to diffuse into the blood?
the lungs causes oxygen from the water to diffuse into the blood
