Answer:
Enzyme-linked
Explanation:
The cell surface receptors that have intracellular domains associated with enzymes are called enzyme-linked receptors. The added molecule was water-soluble and cannot pass through the membrane to bind to intracellular receptors. Binding of the added molecule to the enzyme-linked receptor led to the activation of associated enzymes to generate the response (down-regulation of expression of the target gene).
Examples of enzyme-linked receptors include tyrosine kinase receptors. Binding of the signaling molecule to these receptors triggers phosphorylation of the intracellular domain which in turn transmits the signal to the cytoplasmic messenger.

Denitrification is the major process involved in converting nitrogen components present in the nitrogen gas and it is released into the atmosphere.
<u>EXPLANATION: </u>
With the help of the nitrogen cycle, the nitrogen that enters living things by nitrogen fixation is converted back into nitrogen and is released in the atmosphere by microbes.
The nitrogen-fixing bacteria converts the nitrogen contents into ammonia by the process called ammonification. Then it oxidizes ammonia to nitrite by the process called nitrification and these nitrates are absorbed by plants.
Then, the bacteria present in the soil convert nitrate back to nitrogen gas which is released back to the atmosphere.
