How do enzymes increase the rate of a chemical reaction? Why is Kcat/Km referred to as the efficiency of an enzyme? Why does pH change enzyme activity? How do enzyme molecules react with reactants to produce substrates? Briefly describe the role of enzymes during the regulation of metabolism...
Previously, the researchers used SLAC's Stanford Synchrotron Radiation Lightsource (SSRL) to obtain the structure of the enzyme at very low temperatures using X-ray crystallography. In this study, Medhanjali Dasgupta, a UNL graduate student who was the study's first author, used the Linac Coher...
Explain how the structure of an enzyme relates to how well the function catalyzes chemical reactions. Diagram an enzyme-substrate complex to explain how it works in anabolic and catabolic reactions. Almost no metabolic reaction is able to occur without the help of an enzyme. ...
Carbon dioxide is formed in the cells as a byproduct of many chemical reactions. It enters the blood in the capillaries and is brought back to the lungs and released there and then exhaled as we breathe. RBCs contain an enzyme called carbonic anhydrase which helps the reaction of carbon ...
It appears to be able to interfere with the enzyme acetylcholinesterase that breaks down acetylcholine, which is involved in memory and learning. This means more acetylcholine becomes available to stimulate brain cells. Alzheimer's disease is a condition where there's a relative shortage of ...

The theory of evolution explains how strands of DNA change. An X-ray, cosmic ray, chemical reaction or similar mechanism can modify a base pair in the DNA strand to create a mutation, and this modification can lead to the creation of a new protein or enzyme. The theory of evolution furth...
An enzyme must have a specific geometry (stereochemistry) to allow it to recognize and bind the substrates of the reaction it catalyzes. Additionally, however, proteins must be flexible enough to undergo changes in conformation during their activities. Conformational changes in enzymes are essential ...
How do you assay an enzyme? How do enzymes work? a. They can change the shape of a substrate to make it more reactive. b. They provide the free energy required to catalyze a reaction. c. They decrease the potential energy of the reactants to increase the rate of reaction. d. Th...
Can they change the number of reactions in a body or can enzymes just control the chemical reactions in the body? Enzyme Function Enzymes serve to catalyze the rates of reactions by altering the minimum energy required for the...
