What are the factors that affect enzyme activities?BSC1010C Enzymes & Cellular Regulation Dr. Harris Amylase is an enzyme found primarily in saliva and pancreatic secretions. It catalyzes the breakdown of starch into sugars. A Rate of reaction 0 20 60 40 Temperature, C C Rate of reaction 80 100 B Rate of reaction Enzyme concentration (Substrate concentration always in excess) Substrate concentration (Enzyme concentration constant) The above graphs (A, B & C) provide data on several factors that affect the activity and function of amylase in living organisms. 11. What variables are compared in graph A? What information can be obtained from this data?AM Fri May 21 Take Quiz Coenzymes function to O denature the enzyme, stopping the chemical reaction from occurring. interact directly with enzymes, either enabling the reaction to occur or making the substrate-enzyme interaction more efficient. O change the shape of enzymes, allowing different additional substrates to bind. O dilate blood vessels, allowing more blood to flow, allowing more substrate to reach enzymes. O absorb excess hydrogen and hydroxide ions, keeping the pH relatively stable, so that reactions can occur most efficiently. Question 11 1 In the digestive system, which major organ starts the breakdown of proteins? O Mouth O Large intestines O Small intestines O Stomach O Esophagus Question 12 energy is energy found in the bonds of ingested nutrients.
