An excellent review article by Talalay (1965) emphasizes the molecular aspects of enzymatic mechanisms in steroid biochemistry, including considerations similar to those concerned with non-enzymic steroid-protein complexes.doi:10.1007/978-3-642-46262-7_16Ulrich Westphal...
There is still so much we don’t understand about the origin of life on Earth.The definition of life itself is a source of debate among scientists, but most researchers agree on the fundamental ingredients of a living cell. Water, energy, and a few es... life biochemistry hydrothermal vent...
12. The reactants of enzyme-catalyzed reactions are known as . Substrates 15. How do most cells regulate the activity of enzymes? Most cells contain proteins that help turn key enzymes “on” or “off” at critical stages in the life of the cell....
How do you speed up enzymes? Add more of the enzyme. Warm up the enzyme! Don’t warm it too much or something may happen Once the enzyme and substrate are together, the enzyme holds the substrate so the reaction can occur. Once the reaction is over, the enzyme unlocks the product and...
Nanozymes are a new concept created by Chinese scientists and have been recorded in textbooks and encyclopedia. Prof. Erkang Wang pioneered to utilize nanozymes for analytical detection and then published a review entitled “Nanomaterials with enzyme-like characteristics (nanozymes): next-generation artifi...

The International Union of Biochemistry suggests the standard assay temperature to be 30 °C. Almost all enzymes are extremely sensitive to pH change. Just some enzymes feasibly operate with pH above 9 and below 5. Most enzymes have their pH – optimum near to neutrality. Any alteration of pH...
Cells face various allocation problems demanding decisions on how to distribute their finite resources. They decide which enzymes to produce at what quantity, but also where to position them. Here we focus on the spatial allocation problem of arranging e
Answer: Reactants (substrates) Products What about enzymes makes the rate of the reaction increase? Answer: They have a specific shape that allows the substrates to fit perfectly together thus making the reaction happen quickly. The proximity of the substrates allows chemical bonds to be created ...
