Answer:
A. a protein
Explanation:
Proteins function as enzymes in most of the catalyzing reactions, that increases the rate of reaction within cell.
Proteins are consist of multiple numbers of amino acids and the twisting and folding amino acids provide a unique identity to enzymes. Not all the proteins are enzymes but all the enzymes are proteins.
For example: Trypsin, Pepsin, and Lipases.
Hence, the correct option is "A. a protein".
Answer:
The enzyme influences the speed of change from substrate to product. Enzymes are released as substrates in a chemical reaction. An enzyme is a special kind of substrate in a chemical reaction.

Answer:
A. The process of reciprocal inhibition.
Explanation:
In our body, not all the muscles contract and relax simultaneously. The muscle supporting certain reflex are contracted while the others need to be relaxed at that time. In the process of reciprocal inhibition, when a message of contraction is sent by the central nervous system to the agonist muscles, the tension in the antagonist muscles is inhibited by the impulses from the spinal interneurons so that the antagonist muscles get relaxed simultaneously and the reflex action can be completed without causing any damage to our muscular system. If both agonist and antagonist muscles will contract and relax simultaneously, there may be tear in the muscles that's why reciprocal inhibition is a important phenomena occurring in our body.
