Explain how the structure of the cell membrane contributes to its function.

• The cell membrane is rigid, providing structural support.

• The cell membrane is selectively permeable, allowing certain substances to pass through while blocking others.

• The cell membrane is impermeable, preventing any substances from entering or leaving the cell.

• The cell membrane is composed of DNA, which controls cell activities.

Which of the following statements best explains the lock-and-key model of enzyme activity?

• Enzymes can bind to any substrate.

• Each enzyme has a specific substrate that fits its active site.

• Enzymes are permanently altered after binding to a substrate.

• Enzymes can bind to multiple substrates at the same time.
