Biology · Secondary 3 · Medium · Effect of temperature and pH on enzymes
The graph shows how the rate of an enzyme‑controlled reaction changes with temperature. Between 10°C and 35°C, the rate increases. Which statement best explains this increase?
- The enzyme becomes denatured and works faster.
- More enzyme‑substrate collisions occur per second.
- The active site changes shape to fit more substrates.
- Substrate concentration increases automatically.
