• B) The reaction rate is independent of substrate concentration.
• C) The reaction rate increases but then decreases, forming a bell-shaped curve.
• D) The reaction rate decreases with increasing substrate concentration.
• E) The reaction rate increases with increasing substrate concentration up to a point, above which the rate remains constant.
