example of technology advancement. We accepted things and events attributing their cause to nature and her wrath. However‚ advancement and technology could give us a different picture. This way‚ it has become a habit with us to accept everything that history states and dictates. On the process the modern world has found ways to offer a different view on it. In other words‚ the modern world has turn impossibilities to possibilities. William’s report gives an insight into this. A mummy scanned after a thousand

Enzymes An enzyme is a protein used to speed up the rate of a chemical reaction. Because they regulate the rate of chemical reactions‚ they are also called catalysts. There are many‚ many different types of enzymes‚ because for each chemical reaction that occurs‚ an enzyme specific to that reaction must be made. To act on a substrate‚ an enzyme must contain an active site. The active site is the area on the enzyme that allows the substrate and enzyme to fit together. The amino acids that are present

“I Need To Be Myself‚ I Can’t Be Anyone Else.” “I was born to be true and not to be perfect‚” Epey said in his speech. Epey is the winner of the trending segment in It’s Showtime – That’s My Tomboy.

The summer vacation finally started. I was on a ship to Alaska. But that night the ship hit an iceberg. The ship was sinking and everyone was hurrying to the emergency exit. The exit was locked.

But I still dove out of the window so as to escape. A big piece of glass was stuck to my arm. I had been floating on the sea for days

INTRODUCTION OF ENZYMES Enzymes are complex proteins that cause a specific chemical change in all parts of the body (David C. Dugdale‚ 2011). When we understand enzymes we understand cells (Marshall Brian‚ 2001). In many organisms most chemical reactions are catalyzed -when a substance speeds up the rate of a chemical reaction- by enzymes. Each enzyme controls a certain function that happens in a cell. Still each one has its own process and rate that it converts molecules. Studying enzymes shows how chemical
