Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which of these is most likely an enzyme? (Based on the suffix)
A
Sucrose
B
Galactose
C
Fructose
D
Amylase
Explanation: 

Detailed explanation-1: -The suffix-ase is used in biochemistry to form names of enzymes. The most common way to name enzymes is to add this suffix onto the end of the substrate, e.g. an enzyme that breaks down peroxides may be called peroxidase; the enzyme that produces telomeres is called telomerase.

Detailed explanation-2: -The names of most enzymes end in the suffix-ase. The rest of the name is derived from the substrate acted upon. For instance, the enzyme that breaks down protein is known as PROTEASE and the enzyme responsible for forming, or polymerizing, DNA is known as DNA POLYMERASE.

Detailed explanation-3: -Enzymes can be either anabolic or catabolic. The same enzyme can be used to form smaller molecules from a larger molecule or to do the opposite. An example of a catabolic enzyme is amylase. Amylase converts starch into maltose.

Detailed explanation-4: -What denatures enzymes? There are two main causes for enzyme denaturation: temperature and pH. Enzymes function best at the optimal temperature of an organism.
