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).
fast. Enzymes catalyze all chemical reactions in every pathway of the body. A pathway always involves the action of many enzymes. Letâs briefly go over what each pathway does. Glycolysis is the first pathway to metabolize sugar. This pathway, found in the cytoplasm breaks sugar into 3 C compounds, pyruvate and lactate. ATP is formed. In the mitochondria, the pyruvate dehydrogenase enzyme changes
