Question

of enzymes. CRITICAL THINKING Increased temperature above optimum usually do not effect A. Primary structure B. Secondary structure C. Tertiary structure D. Quaternary structure - PREP BOOK​

Answer 1

Answer:

c

Explanation:

tertiary structure of enzyme is due to ionic bond ,hydrogen bond ,di sulphide linkage

ionic bond strenghth is increase by temprature so not effect of temprature

Answer 2

Answer:

The correct option for this question is C. Tertiary structure.

Explanation:

• The complete polypeptide chain being folded into a certain three-dimensional shape is referred to as tertiary structure. Enzyme tertiary structures frequently have globular, compact shapes. The triose phosphate isomerase (TPI) molecule's tertiary structure. More than one polypeptide chain can combine to produce many proteins.
• As the temperature rises, enzyme activity rises until it reaches its peak at the ideal temperature (around 37°C for most human enzymes). Enzyme activity diminishes as temperature rises over the ideal temperature.
• Enzymes are still proteins, and as with all proteins, they begin to break down at temperatures exceeding 104 degrees Fahrenheit, or 40 degrees Celsius. However, greater temperatures do boost the activity of enzymes and the rate of reactions.

Thus, a greater temperature causes substrate and enzyme collisions to occur more frequently in reactions that are regulated by enzymes. As a result, the reaction happens more quickly.
