Question

Lettered blanks have been left in the following paragraph. Indicate the term that should be found in each blank. (10 marks)

_____(a)_____ are a class of _____(i)_____ found inside cells whose job it is to catalyze chemical reactions. Generally, one _____(a)_____ will affect one chemical reaction, so the collection of _____(a)_____ inside a cell will determine the _____(b)_____ pathways available to the cell. The _____(c)_____ is the material on which the _____(a)_____ acts. The _____(a)_____ and the _____(c)_____ form the _____(d)_____ complex. If there is sufficient energy called the _____(e)_____ energy, the _____(d)_____ complex breaks down to form _____(f)_____. Since the _____(a)_____ is not destroyed in the reaction, a single _____(a)_____ molecule can be used many times.

Because the functioning of _____(a)_____ depends on four levels of structure, the functioning of a(n) _____(a)_____ can be adversely affected by environmental conditions such as _____(g)_____ and _____(h)_____. Extremes of these conditions cause the _____(i)_____ to _____(j)_____ and the _____(a)_____ stops functioning.

Answer 1

(a) Enzymes are a class of (i) Proteins found inside cells whose job it is to catalyze chemical reactions. Generally, one (a) Enzyme will affect one chemical reaction, so the collection of (a) Enzymes inside a cell will determine the (b) Metabolic pathways available to the cell. The (c) Substrate is the material on which the (a) enzyme acts. The (a) Enzyme and the (c) Substrate form the (d) Enzyme-substrate complex. If there are sufficient energy called the (e) activation energy, the (d) Enzyme-substrate complex breaks down to form (f) Products. Since the (a) Enzyme is not destroyed in the reaction, a single (a) Enzyme molecule can be used many times.

Because the functioning of (a) Enzyme depends on four levels of structure, the functioning of a(n) (a) enzyme can be adversely affected by environmental conditions such as (g) Temperature(heat) and h) pH. Extremes of these conditions cause the (i) Proteins to (j) Degrade and the (a) enzyme stops functioning.
