Translation and temperature

A moderate increase in temperature apparently increases the efficiency of translation. Why does this happen?

Because chemical reactions rely on molecules randomly numbing into each other, and more temperature means faster molecules that bump into each other more often.

If you increase the temperature too much, then proteins tend to break, hence the qualifier "moderate".

If you plot reaction speed vs temperature, biological reactions tend to look like y=e^x, until the temperature gets too high, then the curve instantly drops to 0.
