...enzymes in human cells. Above this temperature the enzyme structure begins to break down (denature) since at higher temperatures intra- and intermolecular bonds are broken as the enzyme molecules gain even more kinetic energy.Also Enzymes have an active site. This is part of the molecule that has just the right shape and functional groups to bind to one of the reacting molecules.  The reacting molecule that binds to the enzyme is called the substrate.At high temperature,the active site is said to be denatured.Therefore,the active site cannot bind with any subtrate anymore.Amylase breaking down the starch suspension into maltose and maltose into glucose when HCL was added into solution B .This is because solution B was hydrolyzed and the H+ ions present break down the bond in between molecules of the solution B The HCl will denature (unfold) the amylase (as noted at the bottom of the link you provided), disrupting...

Investigation of Action of Saliva and 3 M Hydrochloric Acid in Two Carbohydrate Solutions

...Title: To investigate the trajectory of a small ball as it rolls off a surface which is inclined to the horizontal. Objectives: To investigate the trajectory of a two dimensional motion. Apparatus and materials: Ramp, wooden block, pendulum bob, plumb line, steel ball, wooden board, carbon paper, meter ruler, plasticine. Setup: 1. A ramp was set up at the edge of a bench. 2. A plum-line is suspended from the edge of the bench. 3. A wooden board is mounted horizontally using two clamps so that the board is situated about the bottom of the ramp. 4. A sheet of blank paper is placed on top of the board. 5. A piece of carbon paper is placed on the top of the blank paper. The ink-side of the carbon paper is facing down. 6. When a ball was released from the top of the ramp, the ball travelled through a trajectory. Theory: Let: g= 9.80ms-2 u= speed of the ball as it leaves the ramp k= constant y= vertical distance (between the bottom of the ramp and the top of the board) x= horizontal distance (between the plum-line and mark on the paper) The equation which relates x and y is yx=g1+k2x2u2+k Procedure : 1. The ball was positioned at the top of the ramp. The ball was released so that it rolls down the...
