Contemporary Examples. â 1 competition is there, of course, but I think there is enough business for everyone as long as the demand is there,â he says. Ghost Ships of the Mediterranean Barbie Latza Nadeau January 5, 2015. 2  I am fighting that quota because I am an advocate of competition.
The correct answer is bâcatalyzing a series of reactions using multiple different enzymes B. Answer b is correct. The enzymes within a multienzyme complex all work on complementary reactions in which the product of one reaction supplies the substrate for the next. The correct answer is bâ C. Answer c is incorrect. Enzymes catalyze reactions by lowering the activation energy; however, this property is not unique to multienzyme complexes. The correct answer is bâ D. Answer d is incorrect. Multienzyme complexes contain more than a single enzyme and although they do lower the activation energy, that property is not unique to these complexes.
For an enzyme to work it must bind to a specific substrate molecule, using a part of the enzyme molecule called the active site. To do this, the enzyme's active site and the s â¦ ubstrate must have matching (complementary) shapes.The shape of an enzyme molecule depends on the exact way in which the molecule folds up.When enzymes are heated the weak bonds which hold the molecules in their precise shape are broken, and the enzyme molecule unwinds into a random shape. It can no longer bind with its substrate so it no longer has any activity.This unwinding of a protein molecule is called denaturation.hen enzymes are heated the weak bonds which hold the molecules in their precise shape are broken, and the enzyme molecule unwinds into a random shape.
