Premium Enzyme Catalysis Metabolism
Enzymes control the rate of metabolic reactions‚ they act as biological catalysts‚ which means they are used but not used up and they also control the speed of the reaction. Enzymes are proteins which means that anything that disrupts this structure such as high temperature or change in pH will affect the enzyme activity. There are many factors affecting enzyme action for example temperature effects them‚ if the Increasing the heat gives molecules more kinetic energy so they vibrate this can then

Enzyme Lab: Peter Kuetzing – 10/4/2012 – F Block 1. How does changing the concentration of enzyme affect the rate of decomposition of H2O2? When more enzymes is added the rate of reaction speeds up. In this case‚ H2O2 will produce more O2‚ in return the kpa/min will go up. 2. What do you think will happen to the rate of reaction if the concentration of enzyme is increased to five drops? Predict what the rate would be for 5 drops. I think that the rate of reaction will slightly increase from

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

EXPERIMENT 1: REACTIONS OF ENOLATE IONS WITH CARBONYL GROUPS Aims In this experiment we used two techniques for the reactions of enolate ions with carbonyl groups. One technique used was Doebner reaction and the other technique used was Claisen-Schmidt reaction. Therefore the aim of this experiment is to synthesize trans p-methoxycinnamic acid and to synthesize dibenzalacetone via an aldol condensation reaction between acetone and benzaldehyde. The products would be recrystallized using ethanol

Green Marketing or Green Washing In the competitive market place‚ companies will do anything to draw consumers attention towards their products or services. Today‚ many businesses are engaging in green marketing‚ the practice of promoting environmentally-safe products. Concerns are rapidly growing that some green marketing is just green washing. Companies are guilty of green washing when they mislead their buyers into thinking that their products are environmentally-friendly. They tend to hide

if everyone routinely washed their hands ‚ a million deaths a year could be prevented... (CDC‚ 2013)" Studies have shown that hand washing may be the single most important act to help stop the spread of infection. Hand hygiene is one of the most important steps we can take to avoid getting sick and spreading germs to others. A lot of diseases are spread by not washing hands with soap and water. sometimes clean running water may not be available‚ so use soap and the available water or hand sanitizer

Ablutophobia The Fear of Washing or Bathing Ablutophobia‚ defined as the fear of washing‚ bathing and cleaning is an intense fear that poses no or little danger. Just thinking about bathing could cause a number of symptoms such as: breathlessness‚ dizziness‚ excessive sweating‚ nausea‚ dry mouth‚ feeling sick‚ shaking‚ heart palpitations‚ inability to speak or think clearly‚ a fear of dying‚ becoming mad or losing control‚ a sensation of detachment from reality or even an anxiety attack.
