Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]

Sam is studying the effects of temperature change on a specific enzyme, c at al as e . This enzyme is found in cells and helps break down hydrogen peroxide. As part of her project, she measures the rate at which hydrogen peroxide is broken down by catalase at 20, 25, 30, and 35 degrees C.Which question BEST describes Sam’s science research project?

A	How are enzymes affected by changing temperature?
B	Is catalase able to function at all temperatures?
C	How is the enzyme catalase affected by changes in temperature?
D	Can cells survive if the temperature falls to 20 degrees Celsius?

Explanation:

Detailed explanation-1: -Catalase is a key enzyme which uses hydrogen peroxide, a nonradical ROS, as its substrate. This enzyme is responsible for neutralization through decomposition of hydrogen peroxide, thereby maintaining an optimum level of the molecule in the cell which is also essential for cellular signaling processes.

Detailed explanation-2: -The conversion of hydrogen peroxide to water and oxygen by catalase is a well understood two-step process whereby catalase heme Fe+3 reduces one molecule of hydrogen peroxide to water, generating a covalent Fe+4O oxyferryl species and a porphyrin cation radical.
