Question

When students investigated the effect of temperature on lactase activity, many found ONP production to be highest at 100° Which of the following best explains this result? O Lactase functions well in boiling water. O Covalent bonds break spontaneously at high temperature. O Thermal agitation increases the rate at which substrates bind to enzymes. O All of these are correct.

Answer 1

All of the above are correct

The first statement is correct because if the amount of product is highest at hundred degree Celsius, then it can mean that the enzyme which is forming the product works best at this temperature.

Second statement is also correct because at high temperature, covalent Bond can break easily.

Third statement is correct because as the temperature increases, the rate of movement of molecules also increases. This will lead to an increase in the velocity of substrate and enzyme and therefore more substrate and enzyme molecules will collide and bind with each other. This will result in the more amount of product being formed.

Please rate high.
