Experiment 6 Properties of Enzymes

(living cells) (catalysts)

Thousands of enzymes are found in (_____) where they act as (______) for the thousands of chemical reactions which occur.

(food processing and clinical diagnoses)

In addition to making life possible, many enzymes have numerous applications that affect our daily lives in other ways such as (_______/_______).

(rate)(reactions proceed) (biochemistry)

Enzyme experiments are ideal for "hands on" opportunities and since several factors affect the (____) at which enzymatic (___________), an enzyme experiment presents many opportunities in the (__________) laboratory.

(Hydrogen peroxide (H₂O₂) (harmful) (immediately) (catalase)

(_____________) is naturally formed in living organisms, however it is very (_________) and is broken down (________) by several enzymes including (_________).

(hydrogen peroxide) (water) (oxygen) (acatalasemia) (low catalase activity)

This enzyme catalyzes the breakdown of (___________) to (____) and (_____). Persons with (__________) (a hereditary condition) have extremely (___________).

(Bromelain) (stem) (fruit and core)

(__________) is an enzyme derived from pineapples. Although it is abundant in pineapple (_______), it can also be found in its (______/______.)

(protease) (hydrolyze proteins) (tongues)(pineapple) (oral mucous layer).

(Bromelain) This enzyme is a (________), which means that it can (________). This is the reason why some people have sensitivity in their (________) when eating (________) because it can compromise the (___________).

(rennin) (chymosin) (calf) (young bovines).

(________) (also known as (________) is an enzyme obtained from the fourth stomach of a (____) or other (_________).

(soluble casein molecle ) (insoluble casein) (proteolytic enzymes) (casein) (rennin).

It causes rapid clotting of milk by causing certain bonds to break in the (____________) (milk protein) converting it to the (________), thus producing "curdled" milk. Most other (_________) will curdle milk, but they also cause continued breakdown of the (_____), unlike (_______).

(Human infants) (curdling), (slow digestion) (nutrient.)

(________) also produce rennin. This helps in the (_______) of the milk, which helps in the (__________) and complete absorption of (______).
