Facilitated diffusion uses proteins to move a molecule across the cell membrane without energy.
Its too large
When a signal molecule activates a transport protein on the cell membrane, it undergoes a conformational change that opens a channel or alters its affinity for the molecule it transports. This allows specific substances to move across the membrane, facilitating cellular communication and maintaining homeostasis.
Facilitated diffusion occurs when a membrane protein binds to a molecule on one side of the cell membrane and then releases it on the other side. This type of transport does not require energy and relies on the concentration gradient to move molecules across the membrane.
Carrier proteins facilitate the transport of substances across the cell membrane by binding to the specific molecules they transport and undergoing conformational changes to move the molecules across the membrane. This process is often referred to as facilitated diffusion. It allows for the transport of specific molecules, such as glucose or ions, across the membrane, down their concentration gradient.
Proteins are to large or Oxygen is much smaller than a protein.

Passive Transport
The molecule will be transported across the membrane by way of a transport protein or protein channel.

the processe is called osmosis Try again, this time use the term "facilitated transport" since a protein molecule is helping.
Facilitated diffusion involves the movement of molecules across a cell membrane with the help of transport proteins. The steps include the binding of the molecule to the specific protein, conformational changes in the protein to carry the molecule across the membrane, and the release of the molecule on the other side of the membrane. This process does not require energy input from the cell.
