Horseradish peroxidase write up

Ama is described as a sticky substance that clogs the myriads of tiny tubes that make up the body. There are many Ayurvedic procedures to remove ama from the body. Some of these procedures are done daily, others seasonally, and they are part of the normal routine of life. For Ayurveda, maintaining a body free from ama helps provide the foundation for disease prevention and health promotion.

Horseradish peroxidase write up

Enzymes are generated by our body, and are usually categorized as proteins. It has an active site, which is opened until a substrate binds to it and activates it to play a specific function in a chemical reaction.

Horseradish peroxidase write up

In biology terms a substrate is the surface or medium on which an organism grows or is attached. In addition the chemistry term for a substrate is simply the substance that is acted upon by an enzyme or the molecules at the beginning of the reaction.

A great example of an enzyme and substrate reaction is curd formation, which is a reaction where rennin is added to milk. At the end of the reaction a product is made. A good way to memorize what happens in these chemical reactions is by symbols, such like this: Enzymes are selective for their substrates and speed up only a few reactions from among many possibilities, the set of enzymes made in a cell determines which metabolic pathways occur in that cell.

In this experiment your enzyme extract will be the horseradish mixed with the citrate-phosphate buffer and the substrate will be H2O2. These will be kept separate until mixed in different temperature surroundings.

A lot of factors contribute to the way an enzyme works in a cell. For example temperature, PH, inhibitors, enzyme concentration, and substrate concentration all contribute to the way enzyme reactions occur.

The main focus on this experiment is temperature. Furthermore heat enhances the kinetic energy of the participant molecules, which results in more number of collisions between them. These collisions of molecules cause the reaction to happen better and quicker.

So if he environment is cold instead of hot then the molecules move slower causing a less chance of these molecules colliding. Meaning in hotter temperature the reaction will be faster than in colder environments. Even though this is true in extreme hot temperature the opposite occurs, which the enzyme becomes denatured and fails to carry out its function.

Denature is when something unfolds and cannot follow up with its function due to its structure. A good temperature for enzyme reaction is our body temperature. Here we want to test this and make sure that with different temperature the warmer it is the more robust the reaction will be.

Scientist are constantly trying to catalyze reactions using enzymes. Catalyze is another way of saying accelerate a reaction. The PctV reaction comprises a transamination and two dehydration reactions. In this lab you will experience a simple enzyme reaction using horseradish and temperature.

When cutting off a small piece of horseradish with a knife and measuring it to about one gram we placed it in the blender with about mL of the buffer. Once both are placed in the blender we blended it for about seconds.

After this was blender we used a double layer of cheesecloth to pour what we blended into a beaker so any left over chunks of horseradish was left out. This was labeled our enzyme extract. We use this throughout the lab experiment. The spectrophotometer is a machine used to calculate the Absorbance.

Even though we are calculating the rate dependent on the temperature in its environment we can calculate rate using absorbance and the time. The formula for rate is: Absorbance Final-Absorbance Initial Time Final-Time Initial In order for the experiment to work we first set the Spectrophotometer a wavelength and blanked it using our blank test tube.

In the lab room we had certain environments to make sure the enzymes reactions would occur. We had a bucked of ice, room temperature, body temperature, and boiling point.Looking for online definition of horseradish peroxidases in the Medical Dictionary?
