Question

Reaction rates

1. 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
2. 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?
3. 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?
4. 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?
5. 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?

Answer 1

1. These enzymes operate most quickly at 30°C and become slower as the temperature is lower, and also when is higher.

2. Six fragments

3. Eighteen complete triglycerides

4. Sixteen glycerol molecules

5. Nine peptides

Step-by-step explanation:

Question 1. it's known that at low temperatures the movement of particles is slower, and being 30°C the optimal temperature for these enzymes to work, below 30°C these enzymes will work slower. As these enzymes are also temperature-sensitive, at higher temperatures they tend to denature, and will work slower as temperature increases, and will stop when are totally denatured

For questions 2 to 5, we divide the reaction time in any of the group of enzymes involved in catalysis, between the 1 reaction time to obtain the performance ratio. That means number of fragments, segments, or molecules rendered after hydrolysis, or synthesis, in the respective given sort of catalysis.
