Background Paragraph: Most chemical reactions within organisms would be impossible under the normal conditions within cell. For example, the body temperature of most organisms is too low for reactions to occur quickly enough to carry out life processes. Reactants may also be present in such low concentrations that it is unlikely they will meet and collide. Therefore, the rate of most biochemical reactions must be increased by a catalyst. A catalyst is a chemical that speeds up chemical reactions. In organisms, catalysts are called enzymes . 
Story: Mike is a biochemist, working for a science lab. Today, he has two organisms to investigate, organism A and organism B. He notices that organism A has enzymes, but organism B lacks enzymes. He needs to figure out how these conditions would affect the organisms.
In which organism the the chemical reactions would be slower, organism A or organism B? In which organism the the chemical reactions would be speedier, organism A or organism B? Under normal conditions, in which organism the chemical reactions would be less plausible, organism A or organism B? Under normal conditions, in which organism the chemical reactions would be more plausible, organism A or organism B? Which organism would less likely be able to carry out life processes, organism A or organism B? Which organism would more likely be able to carry out life processes, organism A or organism B? Would organism A see speedier or slower chemical reactions than organism B? Would organism B see speedier or slower chemical reactions than organism A? Would the chemical reactions be less plausible or more plausible in organism A than in organism B? Would the chemical reactions be less plausible or more plausible in organism B than in organism A?
