size/ polarity can be the factors
Polarity and size are factors that determine whether a molecule can cross a cell membrane.
In a hydrogen ion pump, the energy is used to join small molecules together to make larger ones which factor most likely Has greatest effect on the number of molecules mitochondria can produce

Polarity
If the large molecule won't pass through the membrane by diffusion, it might be dragged through the membrane by "endocytosis".
No, carbon dioxide does not need a transport protein to cross the cell membrane. It can pass through a membrane by diffusion.

mass
Usually its size and net charge.
Lipid solubility determines if it will diffuse across. The presence of specific protein carrier molecules determines if it will be transported across the membrane.

The Gonhiqule depends on a molecule and cross the plasma membrane in an animal cell, but is a different story for the plant cell because of the cell wall.
