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.
Answer: option D. it acts as a reactant in a chemical reaction.
The substrate is the the chemical species in an organic reaction that reacts to form other product, so the substrate is a reactant. The enzymes can act over specific substrates to accelerate the reaction. While the enzymes are not consumed (they are catalysts) the substrates are consumed.
