Membrane proteins that bind to signal by which cells communicate are called receptors are generally transmembrane protein.
<h3>What is the function of the stop sequence to a transmembrane protein? </h3>
When the protein presents an internal signal sequence (SSI), this sequence, in addition to directing the transport of the translational complex to the REG, will also act as an SPT, with the carboxy-terminal portion of the protein facing the lumen. from the reticulum or into the cytosol.
in this case, many transmembrane proteins function as gateways to permit the transport of specific substances across the membrane.

Explanation:
Answer: Nitrogen-fixing Bacteria
Explanation:
In the Nitrogen cycle, nitrogen fixing bacteria are very important in ensuring that plants get nitrogen to enable them grow and as animals have to eat plants, these bacteria are essential for our survival as well.
Plants are unable to use atmospheric nitrogen but nitrogen-fixing bacteria are able to synthesize ammonia from atmospheric nitrogen. They can then convert this to Nitrites and Nitrates which are more useful to plants and animals by extension.
