Reaction rates
Suppose that the enzymes that catalyze the dehydration synthesis and hydrolysis reactions that build and break down organic compounds are sensitive to temperature. They operate most quickly at 30°C and become slower as the temperature cools. Match the result of the reactions below.
1. At 20°C the enzyme that catalyzes the breakdown of polysaccharides functions at 1 reaction every 20 microseconds. If this enzyme catalyzes hydrolysis reactions of a very long polysaccharide molecule for 120 microseconds, into how many segments would this long polysaccharide be cut?
2. At 20°C the enzyme that catalyzes the synthesis of triglycerides functions at 1 reaction every 25 microseconds. If this enzyme catalyzes dehydration synthesis reactions for 450 microseconds, bonding fatty acids to glycerol, what is the maximum number of complete triglycerides that could be formed if no fatty acids were bonded to glycerol at the beginning of the reactions?
3. At 25°C the enzyme that catalyzes the hydrolysis of fatty acids from triglycerides functions at 1 reaction every 6 microseconds. If this enzyme catalyzes hydrolysis reactions for 96 microseconds, what is the maximum number of glycerol molecules that could be stripped of all of their fatty acids?
4. At 25°C the enzyme that catalyzes the hydrolysis of proteins functions at 1 reaction every 3 microseconds. If this enzyme catalyzes hydrolysis reactions of a very long polypeptide molecule for 27 microseconds, how many segments would the polypeptide be cut into?
