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).
Define the two catabolic pathways: Fermentation â a partial degradation of sugars that occurs without the use of oxygen. Cellular respiration â when oxygen is consumed as a reactant along with the organic fuel; most efficient catabolic pathway; mitochondria house most of the metabolic equipment needed.Use the following terms correctly in a sentence: redox reactions, oxidation, reduction, reducing agent and oxidizing agent.In redox reactions, oxidation (the loss of electrons from one substance) and reduction (the addition of electrons to another substance) occur.efine the two catabolic pathways: Fermentation â a partial degradation of sugars that occurs without the use of oxygen.
