Answer:
c) allowing an organism to adjust to changes in environmental conditions
Explanation:
A stimulus can be defined as any change in the external or internal environment that produces a corresponding response in the organism. These responses enable the organism to maintain an internal equilibrium (homeostasis). Gene expression in prokaryotes, which are the simplest forms of life, is highly regulated by environmental stimuli. Some examples of stimuli known to regulate gene expression patterns in prokaryotic organisms are light, water, pressure, temperature, etc.

1. The statement above is TRUE. 
There are different types of enzymes which perform different functions. Some enzymes are capable of limiting chemical reaction, stopping the reaction from moving forward, such type of enzymes are called REGULATORY ENZYMES. This type of enzyme regulate the activities of other enzymes. The use of regulatory enzymes is one of the means which the body used to control biochemical reactions. 
2. A chemical reaction producing energy for the cell is GLYCOLYSIS.
Glycolysis is the biochemical process by which the glucose molecules are broken down in order to produce energy for the body. <span>Embden-Meyerhof Pathway is one of the major pathway of glycolysis but it is not the only one, there are other glycolytic pathways in living organisms. Glycolysis is the principal way by which energy is supplied to the cells.</span>
