Consider some of the widespread global issues that we face here on Earth and briefly describe them. Then, choose one of the space research technologies discussed in the unit OR that you
find online through some brief research (but may not be one discussed in the video, and explore
how it could help us research, learn more about, or address this particular issue (similar to how
Wood did in the video) in one to three paragraphs.

Lactase is essential for digesting lactose in milk. this enzyme is specific for this sugar. why? molecules and active sites vary in size; only properly sized molecules can fit.there is a precise compatibility between the active site and the lactose molecule.specificity refers to the action of the enzyme, such as hydrolysis, and relatively few molecules can be hydrolyzed.reaction-specific enzymes assume a fit by folding around the most numerous substrate molecules.
