Structure : Form 4 Theme : Chemical Composition Of The Cell Bil : (616) Question : Which of the accompanying explanations with respect to chemicals is valid? A. All catalysts in living beings have an ideal temperature of 37 °C. B. Catalysts increment the actuation vitality for the responses they catalyze. C. Catalysts are denatured at 0 °C. D. Compounds work as natural impetuses Answer : D Reason: The ideal temperature is the temperature at which the pace of response is at a greatest, which is around 35 40OC. Over the ideal temperature, the expanded motor vitality cause the synthetic bonds, which hold the protein atom fit as a fiddle, to slow down. For some creatures, the pace of responses stops at 60OC because of complete denaturation of body compounds. Proteins work as natural impetuses Structure : Form 4 Subject : Chemical Composition Of The Cell Bil : (617) Question : The chart shows the lock-and-key component of chemical activity.
