Question

enzymes
the active site of an enzyme is the region where substrate bind and
the reaction takes place. the specific shape and chemical properties of
the active site allow enzymes to selectively bind to their
corresponding substrates, ensuring the efficiency and specificity of the
catalyzed reaction.

what feature in the active site of enzymes allows them to
bind selectively with their substrate?

• engulfing capabilities
• specific shape
• chirality

Explanation:

The question is about enzymes and their active site's feature for selective substrate binding. The text states the active site has a specific shape and chemical properties for selectivity. Among the options, "specific shape" matches this description (engulfing capabilities isn't a key enzyme - active - site feature for binding, and chirality is more about molecular handedness, not the main active - site binding feature here).

Answer:

B. specific shape (assuming the options are labeled with "specific shape" as one of them; if the option with "specific shape" is, for example, the second option, then the answer would be the second option with its text, e.g., if the options are: A. engulfing capabilities, B. specific shape, C. chirality, then the answer is B. specific shape)
