○ denaturation
○ homeostasis
○ replication
○ transcription

multiple choice 5 points
the diagram below shows an enzyme - substrate complex.
structure x
structure y
structure z

Explanation:

To solve this, we analyze each option:

• Denaturation: Enzymes (proteins) lose their specific 3D structure (including active site shape) at high temps or extreme pH, which matches "distortion of enzyme molecules at high temperatures".
• Homeostasis: Maintenance of internal stability in organisms, not related to enzyme shape change.
• Replication: Process of copying DNA, not about enzyme structure.
• Transcription: Synthesis of RNA from DNA, irrelevant to enzyme shape change.

Answer:

A. Denaturation
