Which type of electromagnetic wave travels through space the slowest?

All electromagnetic waves travel at the same speed, (as long as they're all in the same medium).

The speed at which they travel is what we call "the speed of light".  But it's also the speed of infrared, the speed of microwave, the speed of radio, the speed of X-ray, etc.

The complex molecules of carbohydrates, proteins, and fats are transformed by chemical digestion into smaller molecules that can be absorbed and utilized by the cells. Chemical digestion, through a process called hydrolysis, uses water and digestive enzymes to break down the complex molecules.
