Each enzyme produced by the body is specific—meaning it is only able to catalyze a reaction with a certain substrate. what causes an enzyme to be specific? the enzyme's surface folds are complementary to the substrate's surface folds. the enzyme has surface receptors that can recognize specific sequences of dna the enzyme is made out of the same type of molecule as its substrate. the enzyme is only produced an

B.  

The enzyme's surface folds are complementary to the substrate's surface folds.

B. The bacteria would be relatively evenly distributed along the algal filaments.

Explanation:

A) There would be no difference in results.

B) The bacteria would be relatively evenly distributed along the algal filaments.

C) The number of bacteria present would decrease due to an increase in the carbon dioxide concentration.

D) The number of bacteria present would increase due to an increase in the carbon dioxide concentration.

E) The number of bacteria would decrease due to a decrease in the temperature of the water.

When different segments of light was used, largest groups of aerobic bacteria were found in the red and blue regions of light because these regions have been reported to be best efficient for photosynthesis and thus, oxygen production.

If the experiment is repeated without separating the light segment, one would expect a somehow uniform distribution of aerobic bacteria growth along the algal segment since the different light segments in white light are uniformed distributed.

The correct option is B.
