1 Well, you never have to stop! 1 km = 2 * .5 km = 2 * .3 miles = 0.6 miles. 2  So 31 km = 18.6 miles. 3  However, remember this is only an approximation! 4  In this case, because 1 km is a small proportion of the overall figure, just round up to 32 km, which is 4 * 8 km = 4 * 5 miles.
Close. Reaction pathway. Enzymes can be involved at every step in a reaction pathway. At each step, the molecule is transformed into another form, due to the presence of a specific enzyme. Such a reaciton pathway can create a new molecule (biosynthesis), or it can break down a molecule (degradation).
The Alternative pathway (AP) is one of the three pathways of the complement system. The Illustration shows the Alternative pathway. Additional information can be found if you place the cursor on the different parts of the illustration.
