Cells create organized structures by taking in less organized starting materials (ie make proteins from amino acids). If this is true, how do cells not violate the 2nd law of thermodynamics?

In comparison to early life on Earth, organisms today are highly organized and complex. How does this increase in organization over time not violate the 2nd law of thermodynamics?

If it takes nearly 1000 years for the hydrolysis of sucrose, then how is it possible that cells do this each day without waiting 1000 years?
