ENZYME COFACTORS AND INHIBITORS 1. DESCRIBE THE GENERAL ROLE OF COFACTORS IN ENZYME ACTIVITY. Some chemicals enhance an enzyme’s activity‚ which is what cofactors function to do. They are a non-protein component of an enzyme and may be organic molecules (called coenzymes) or inorganic ions. 2. (A) NAME FOUR HEAVY METALS THAT ARE TOXIC TO HUMANS. Four heavy metals that are toxic to humans are: 1. Cadmium (Cd) 2. Lead (Pb) 3. Mercury (Hg) 4. Arsenic (As) (B) EXPLAIN IN GENERAL TERMS WHY THESE

Investigating the effects of changing temperature on the activity of enzymes Background information: Renin is an enzyme that catalyses the coagulation of milk. It is found in the stomach of many animals and is used in making cheeses and junkets. It is found in the gastric juices or gastric mucosa of many mammals‚ including humans. In the human stomach‚ particularly those of infants‚ rennin works to curdle milk so that pepsin‚ another stomach enzyme‚ can further breakdown the proteins into absorbable amino

The final compound which I am going to look at is 4-aminobenzenecarboxylic acid. The compound is also known as 4-Aminobenzoic acid. The molecular and structural formula of the compound is C7H7NO2 which means that the compound consists of seven carbon atoms attached to seven hydrogen atoms along with one nitrogen atom and two carbon atoms attached as a carbon-oxygen double bond. The displayed formula for the 4-aminobenzenecarboxylic acid compound is shown and it shows the formula in a ring form therefore

Matthew Saldanha Bio DCP lab-Catalase experiment Aim: To investigate enzyme kinetics‚ using different concentration of the enzyme. Hypothesis: The assay system used in the lab consists of a filter paper disc coated with the enzyme and the dropped into a papercup of substrate (Hydrogen Peroxide). As the hydrogen breaks down the hydrogen peroxide into hydrogen and oxygen gas‚ the bubbles of oxygen gas collect underneath the filter and make it

Cellular Biology furthers technology-Enzymes in the Dairy Industry Since ancient times‚ enzymes have played an important role in food production. Especially in the diary industry‚ some enzymes are required for the production of cheese‚ yogurt‚ and other dairy products‚ while others are used in a more specialized fashion such as improving texture or flavour of the product. Enzymes are used to catalyze the desirable reactions in industrial processes. Today‚ enzyme applications in such processing get

Lambda DNA with restriction enzymes. Aim: The objectives of this experiment are: Become more familiar with using micropipettes. Use restriction enzymes to cut DNA at specific sites. Use Ligase to rejoin some of the cut/separated DNA fragments. Learn to separate DNA using electrophoresis. Introduction: Restriction enzymes are proteins which cut dsDNA at specific regions depending on the enzyme used‚ determined by the nucleotide sequence of the DNA‚ i.e. each enzyme recognises specific nucleic

It would be impossible to categorize all potential causes for alarms in all existing network systems however‚ understanding some common alerts and categories is essential for any network manager. Many Network Management Systems have a log and event manager that collects data

Assignment Week 4 Chapter 11 20. A parallel RL circuit has values of IL = 240 mA and IR = 180 mA. Calculate the magnitude and phase angle of the circuit current. It=√ IL^2 + IR^2= √ 240mA^2 + 180mA^2= 0.3 x 10^-3= 300mA θ= tan^-1(-IL/IR)= (-240mA/180mA)= -53° 300mA∟-53° 22. Calculate the total impedance for the circuit shown in Figure 11.38b. It= √IL^2 + IR^2= √800mA^2 + 120mA^2= 0.808949 x 10^-3= 808.95mA Zt= Vs/It= 120V/808.95mA = 148Ω θ= tan^-1(-IL/IR)= (-800mA/120mA)= -81.5= 82° 148∟82° 24
