Question

2) 2017 11:55 PM 35.8/100 Print calculator Periodic Table n 11 of 27 Map Sapling Learning below illustrates the reaction speed (rate) of an enzyme catalyzed reaction at different temperatures. Above what temperature does the speed of the reaction (the reaction rate) slow Number 0 10 20 30 40 50 Temperature C) The reaction rate slows because the temperature affects the function of the enzyme. Keeping in mind that enzymes are proteins, pick the best reason why enzyme function declines above a certain temperature. O The primary structure of the enzyme is disrupted by heat. O Enzyme inhibitors are more active at higher temperatures. O The hydrogen bonds between nucleotides are broken by heat. O Enzyme structure is distorted by heat, and it cannot bind substrate. o Previous 8 Give Up & View Solution Check Answer Next

Explanation / Answer

1) Above 36 degree celcius,the reaction rate decreases.

Enzyme function declines above a certain temperature because enzyme protein denaturation.Secondary and tertiary structure is disrupted due to breaking of secondary and tertiry linkages.

correct option_

Enzyme structure is distorted by heat,and it cannot bind substrate.
