How does the structure of an enzyme affect its function?
A
The structure prevents the enzyme from being affected by temperature changes.
B
The structure enables the enzyme to produce energy directly from substrates.
C
The structure determines the enzyme's ability to bind to specific substrates.
D
The structure allows the enzyme to be used in multiple reactions simultaneously.
Verified step by step guidance1
Understand that enzymes are proteins that act as catalysts in biological reactions, speeding up the rate of reactions without being consumed.
Recognize that the structure of an enzyme is crucial for its function. Enzymes have a specific three-dimensional shape, which includes an active site where substrates bind.
Learn that the active site of an enzyme is complementary in shape to its specific substrate, allowing the enzyme to bind only to that substrate, much like a lock and key mechanism.
Consider how changes in the enzyme's structure, due to factors like temperature or pH, can affect its ability to bind to substrates, potentially inhibiting its function.
Understand that the specificity of enzyme-substrate binding is what determines the enzyme's ability to catalyze a particular reaction, highlighting the importance of its structure in its function.
