In an experiment, the enzyme lactase is added to milk in a test tube. the products obtained are glucose and galactose. which of these correctly explains the function of the enzyme in this reaction?
a) the enzyme molecules collide with the substrate and break it into simpler products.
b) the enzyme has active sites where the substrate binds with the enzyme to break down the sugar.
c) the substrate binds at the non-active sites of the enzyme, where it is broken down into simpler compounds.
d) the substrate breaks the bonds of the enzyme, resulting in the formation of simpler products.

One of the newest applications of cell technology is called cybrid embryos. this process involves replacing the nuclear material of an animal cell with human nuclear material. how might this process affect public policies about research by using stem cells? the same policies and concerns about the use of human embryonic stem cells would most likely apply. the embryos would most likely be treated like traditional animal embryos and regulated accordingly. the process of forming cybrid embryos would most likely be banned by government regulators. the embryos would be treated as regular cells because they are not fully human in origin.
