A
An enzyme that functions properly at 70 degrees Fahrenheit and at a neutral pH.
B
An enzyme that functions properly at 98 degrees Fahrenheit and at an acidic pH.
C
An enzyme that functions properly at 98 degrees Fahrenheit and at a neutral pH.
D

검증된 단계별 안내1
Understand the environment of the human stomach: The stomach is known for its acidic environment, primarily due to the presence of hydrochloric acid, which creates a pH typically around 1.5 to 3.5.
Consider the optimal temperature for human enzymes: Human enzymes generally function best at body temperature, which is approximately 98.6 degrees Fahrenheit (37 degrees Celsius).
Identify the characteristics of enzymes in acidic conditions: Enzymes that are adapted to function in the stomach are likely to be stable and active in acidic conditions, meaning they are designed to work optimally at low pH levels.
Evaluate the given options based on temperature and pH: The correct enzyme characteristics should align with the stomach's acidic environment and the typical human body temperature.
Select the option that matches both the acidic pH and the optimal temperature for human enzymes: The enzyme should function properly at 98 degrees Fahrenheit and at an acidic pH, reflecting the conditions in the human stomach.
