Embedded in the semi-permeable cell membrane are many different types of carrier proteins or channel proteins. These globular proteins allow the transport of specific substances from the outside of the cell into the cell or vice versa.
Specific means each protein can only transport one type of substance across. For example, Protein A can transport Substance X but not Substance Y. Substance Y has to be transported by Protein B which cannot transport Substance X. The specific nature of these globular proteins mean it is easier for these molecules to be transported.

they help transport some substances through the membrane
Carrier proteins of the cell membrane transport substances down their concentration gradient out of or into the cell by facilitated diffusion and active transport.
They help move material in and out of the cell.Read more:They help transport some substances through the membrane :)MORE: Membrane proteins are also important for endocytosis and cell signalling.
In aerobic respiration, electron transport occurs inside the mitochondria. In photosynthesis, electron transport occurs inside the chloroplasts.
system
their functions
The organ that enables animals to perform different functions is the cell. The cell is regarded as the basic unit of all living organisms.
Some membrane proteins are receptors for hormones or other chemicals. Some membrane proteins perform active transport of substances into or out of the cell.
