Question
An enzyme's function is most dependent on its ________.
- size
- temperature
- activation energy
- shape
Solution
The function of an enzyme is most dependent on its shape.
Enzymes are biological catalysts that accelerate chemical reactions in the body, and their activity is closely linked to their three-dimensional structure. The specific shape of an enzyme allows it to bind to substrates (the molecules upon which enzymes act) in a precise manner, often described by the "lock and key" model or the "induced fit" model.
If the shape of an enzyme is altered due to changes in factors such as temperature or pH levels, its ability to catalyze reactions may be compromised. This structural integrity is crucial for the enzyme's functionality, as it determines the specificity and efficiency of the catalytic process. Therefore, while all the options may have some relevance, the shape of an enzyme is the most critical factor that determines its function.
