Question

multiple choice question

which model is sometimes used to describe enzyme-substrate interactions?

antigen-antibody complex
lock-and-key
fluid mosaic

Explanation:

Identify the biological models

• Antigen-antibody complex: Describes immune system recognition.
• Lock-and-key: Describes the complementary fit between an enzyme's active site and its substrate.
• Fluid mosaic: Describes the structure of cell membranes.

Match with enzyme-substrate interactions

• The "lock-and-key" model is a classic model used to describe how a substrate fits specifically into the active site of an enzyme.

Answer:

• Antigen-antibody complex
• Lock-and-key (Correct answer)
• Fluid mosaic
