biophysical measurements of several non-enzymic mesophilic proteins at about -65 °C and reflecting a sharp decrease in protein flexibility as the overall motion of groups of atoms ceases. INTRODUCTION It is now accepted that‚ in general terms‚ enzyme activity is dependent on protein dynamics [1-5]: in other words‚ an enzyme must be flexible to function. A number of biophysical studies [6-12] have shown that the flexibility of mesophilic proteins undergoes a transition at about -65 °C. Below this transition

Bromelain The pineapple plant contains protein-digesting enzymes called‚ as a group‚ bromelain. In the health world‚ these enzymes are regarded as useful in reducing muscle and tissue inflammation (hence the joint pain and wound-healing possibilities)‚ as well as acting as a digestive aid. In the cooking world‚ on the other hand‚ bromelain is regarded as the enemy of the gelatin dessert. If you use fresh pineapple in gelatin‚ the enzyme eats the protein and the gelatin will not gel—in fact

was set but not as firm as cup â»1‚ and cup â»3 with the most tenderizer was not set but had a watery jelly like texture. 4. Does Jell-O contain protein? According to the results in this lab Jell-O must contain protein due to the fact that the meat tenderizer was able to break down the Jell-O much the same as it would break down the proteins in meat. 5. Did the amount of meat tenderizer give different results? The amount of meat tenderizer did give different results‚ cup â»2 with the

Examples may include adenine or guanine. 2. A pyrimidine is a nitrogen-containing base with one ring of carbon and nitrogen atoms. Examples may include cytosine or thymine. 3. A complementary base-pair is a pair of nitrogencontaining bases connected to each other by hydrogen bonds. Examples may include adeninethymine and cytosine-guanine

in active transport is the movement of substance in uphill direction...there is energy requirement(ATP.NA/K pump) 6.A semi permeable membrane means that the membrane is selective in what is allowed into the cell. Some items such as toxins or some proteins are too big to enter the cell with out facilitaion. Other things such as gas and water are small enough to pass through. These items are usually hydrophilic and ionic it makes them easier to pass through the membrane. So basically semi permeable
