Which of the following statements is False?
a. Overheating to 108˚F is likely to disrupt covalent bonds in enzymes.
b. Overly acidic conditions can disrupt protein structure.
c. Low body temperature will reduce the rate at which enzymes catalyze reactions.
d. Considerable
Introduction:
The catalysts that promote the reaction to proceed in a biological environment are called as catalysts. Catalysts are used for accelerating the rate of a biological reaction, in fact, all molecular reaction within an organism need enzymes for its catalysis. Enzymes are said to catalyze in more than 5000 biological reactions. Most of the enzymes are proteins in nature; they increase the rate of reaction by decreasing the activation energy. There are total of six classes of enzymes based on their mechanism
Answer to Problem 1MC
Correct answer:
Covalent bonds in enzymes are stable at
Option (a) is given as “Overheating to
Explanation of Solution
Justify reason for the correct statement:
The rate of enzymatic reaction increases with the increase in temperature. For every
Hence, option (a) is correct.
Justify reasons for the incorrect statements:
Option (b) is given as “Overly acidic conditions can disrupt protein conditions”.
The
Option (c) is given as “low body temperature will reduce the rate at which enzymes catalyze reactions”.
The optimum temperature for the activity of enzymes is around
Option (d) is given as “Considerable metabolic activity is required to maintain a constant environment”.
Metabolic activity generates heat that is required to increase the temperature of the surrounding making it optimum for its activity. Since the statement is true Hence, it is a wrong answer.
Hence, options (b), (c), and (d) are incorrect.
Enzymes are made up of proteins and proteins are made from a specialized arrangement of amino acids. There are various bonds responsible for structural integrity of the protein such as hydrogen bond, ionic bond, bonds formed from the weak Vander-wall force and covalent bond. Some bonds are stable only for a narrow range in conditions such as temperature,
