True or False: Enzymes lower the activation energy for a reaction. I. Genetic message are decoded and used to build protein. II. Identical copies of DNA are made so that genetic information can be preserved and handed down to offspring. II. Genetic messages are read and carried out of the cell nucleus. Which describes the correct order of transferring genetic information in biological system? In base solution, an amino acid is and exists primarily as an anion, while in acid solution, an and exists primarily as a cation. amino acid is protonated, deprotonated deprotonated, protonated zwitterion, protonated zwitterion, deprotonated Structure IV is an example of 美点 OH HO H. но. — ОН но Но -H- но -H но- но но -- но -H- H -O H- -OH H- -OH -OH H- HO- H- -OH он но HO но. ÓH II IV V Which is NOT correctly paired? fibrous protein: spherical alpha helix protein: right-handed coil beta pleated sheet: fully extended peptide chain globular protein: soluble in water
Catalysis and Enzymatic Reactions
Catalysis is the kind of chemical reaction in which the rate (speed) of a reaction is enhanced by the catalyst which is not consumed during the process of reaction and afterward it is removed when the catalyst is not used to make up the impurity in the product. The enzymatic reaction is the reaction that is catalyzed via enzymes.
Lock And Key Model
The lock-and-key model is used to describe the catalytic enzyme activity, based on the interaction between enzyme and substrate. This model considers the lock as an enzyme and the key as a substrate to explain this model. The concept of how a unique distinct key only can have the access to open a particular lock resembles how the specific substrate can only fit into the particular active site of the enzyme. This is significant in understanding the intermolecular interaction between proteins and plays a vital role in drug interaction.
