Question

which of the following statements accurately describes the relationship between temperature and enzyme function? enzymes a and b function equally well at all temperatures. enzymes a and b function best at low temperatures. enzymes a and b function best at narrow range of temperatures. enzymes a and b function best at high temperatures. effects of temperature on two naturally occurring enzymes enzyme a enzyme b rates of reaction temperature (°c)

Explanation:

Enzymes are proteins and their function is highly dependent on temperature. Most enzymes have an optimal temperature range where they function best. Outside of this narrow range, their activity decreases due to changes in their structure (denaturation at high - temps or slow reaction rates at low - temps). The graph shows that both Enzyme A and Enzyme B have a peak in their reaction rates within a specific temperature range.

Answer:

C. Enzymes A and B function best at narrow range of temperatures.
