Question

the model shows the functioning of an enzyme at two different temperatures. 37°c, enzyme, substrate, product, 150 g of product produced every hour; 42°c, enzyme, substrate, product, 70 g of product produced every hour. why is less product produced at 42°c? a the type of product changes at the higher temperature. b the type of substrate changes at the higher temperature. c the structure of the enzyme changes at the higher temperature. d the structure of the substrate changes at the higher temperature. 13. the graph shows the effects of ph and temperature on the activity of an enzyme. enzyme activity, temperature (°c), 0, 36, 37, 38, 39, 40, ph 6, ph 7, ph 8. which statement is correct about the functioning of this enzyme? a the activity of the enzyme is the greatest at a temperature of 38°c when the ph is 6. b the activity of the enzyme is the greatest at a temperature of 36°c when the ph is 7. c the activity of the enzyme is the greatest at a temperature of 39°c when the ph is 8. d the activity of the enzyme is the greatest at a temperature of 40°c when the ph is 7.

Explanation:

Enzymes are proteins and their activity is affected by temperature and pH. High temperatures can denature enzymes, changing their structure and reducing their activity. For the first question, at 42°C, the enzyme's structure changes due to the higher - temperature, reducing product formation. For the second question, by observing the graph, we can see that the enzyme activity is highest at 39°C when the pH is 8.

Answer:

1. C
2. C
