The graph above shows the progress of an enzyme-catalyzed chemical reaction. based on the graph, this enzyme

a. works optimally at 5°c
b. works optimally at 33°c
c. begins to denature above 25°c
d. begins to denature below 20°c

The right answer is C. begins to denature above 25°C

In biochemistry, denaturation is the process by which a biological macromolecule, nucleic acid or protein loses its normal three-dimensional conformation: the proteins lose their folding and unfold, the paired strands of the nucleic acid duplexes separate. This three-dimensional conformation is most often necessary so that the biological macromolecules can fulfill their function and thus the inactive denaturation in general these biological macromolecules.

Denaturation can be done by:

*Temperature: The increase in temperature causes thermal agitation of the atoms of the molecule. This causes a break in intermolecular interactions.

*PH change

*Radiation

*Chemical agents: chaotropic agents, bases, acids, reducing agents, detergents, heavy metal ions.

it also supports my hypothesis. if you rest first you can squeeze the clothespin more times. from the data i collected the average of the eight people concluded exercise makes your muscles more fatigued and less able to squeeze the clothespin compared to resting before squeezing.

the answer is d (apex) good luck : ))
