This allows your body to pass starch through without turning it into glucose. Without starch, fat cannot be stored in the form of carbohydrates and less weight will be gained. This may sound too good to be true. Though carb-cutter does actually block amylase, there are many other factors that go into the breakdown of the carbohydrates. Students at the University of Georgia have taken it upon them to test this rumor and see if carb-cutter really stops the breakdown of starch to helps weight loss.
II. Introduction Part 1: The Effects of Concentration on Enzyme Activity In this experiment, the effects of concentration on enzyme activity were determined by using a spectrophotometer to observe absorbance changes taking place in samples containing a pH 5 buffer, guaiacol, hydrogen peroxide, and different volumes of potato extract. Hypotheses Ho: The amount of enzyme added does not influence the rate of reaction. Ha: The amount of enzyme added does influence the rate of reaction. Part 2: The Effects of Temperature on Enzyme Activity In this experiment, the effects of temperature on peroxidase activity were determined by using a spectrophotometer to observe absorbance changes taking place in temperature treated samples containing potato extract, guaiacol, hydrogen peroxide, and pH 5 buffer.
Table Chainobead Construction with Non-Pop beads | 120 Seconds | 28 | 120 Seconds | 30 | 120 Seconds | 35 | Part 1C: 1. C. What happens to the reaction rate if the enzyme wears a pair of latex gloves? If the enzyme were to wear a pair of latex gloves the reaction rate would slow down because the pop-beads will most likely stick to the latex coding making it a tad bothersome for the enzyme to construct the chainobeads 2.

A con is the higher risk of destruction of normal body flora. Drug allergy, drug toxicity, and creation of resistant microorganisms are also facts that need to be taken into consideration. Narrow-spectrum antimicrobials can only target either Gram-negative or Gram-positive microorganisms or a small variety of microorganisms at the time used. A con is that the bacteria have to be indentified first, before treatment can start. The pros are the reduced risk of creating resistant microorganisms and less chance of harming the host.
The sexually transmissible disease gonorrhea has become increasingly resistant to treatment with antibiotics. What is the most likely scientific explanation? a) The gonorrhea bacteria learned to avoid antibiotics b) The gonorrhea bacteria changed their genes when they sensed antibiotics c) Antibiotic-sensitive gonorrhea bacteria died out, but antibiotic-resistant gonorrhea bacteria have flourished and persisted d) The antibiotic increased the mutation rate in the gonorrhea bacteria e) Both b and d 26. Which statement best describes the relationship between plants and animals on earth? a) Plants produce O2 and sugars from CO2 b) Animals produce CO2 and H2O from sugars and O2 c) Plants produce O2 and sugars and animals produce CO2 and H2O d) Animals produce O2 and sugars and plants produce CO2 and H2 27.
An ACE inhibitor medication inhibits the enzyme that allows this conversion to occur, and therefore, decreases blood pressure. Nursing responsibilities prior to administration: Monitor BP and potassium level (for hyperkalemia). A persistent cough is a common side effect of ACE inhibitors. Angioedema is a rare, but serious side effect. Do not use during pregnancy!
Hypotonic means less salute and more water. For this lab, we can apply these principles to plant cells. The plant cells have a semi permeable membrane so they can experience osmosis and diffusion as discussed earlier. When it comes to the potato cells, added with NaCl (salt) it will experience a reaction changing the form of the cells. The hypothesis of this experiment goes as follows, If we place potato cells in a salt solution, then the cells will shrink.
Antibiotics are produced by microorganism because they inhibit the growth of or kill other microorganisms; they are effective in low concentrations and act on specific species of microorganisms. 3. List four different ways that the antibiotics work to destroy or inhibit microorganisms and for each give named example of an antibiotic exhibiting this type of mechanism. (Note: you need to indicate the different processes or structures affected not simply variations or subsets of a process) Inhibit cell-wall formation: blocks a specific cross linking step in the bacteria in the process of reproduction. E.g.
Codeine is a Food and Drug Administration (FDA) approved drug which branches from the opioid analgesics which reduces and/or eliminates pain. It’s in medicine and is similar yet weaker than morphine. When used, one needs to follows doctor’s orders just like every other medication, because it may result in addiction if the prescription is not followed. It also connects to the human nervous system. Although Codeine is legal in the United States, the U.S. Food and Drug Administration (FDA) and the Drug Enforcement Administration (DEA) supervise its manufacturing because it’s only legal with a prescription.
Investigation of the effect of metal ions on enzyme activity Objective: The effect of lead (II) ion and silver ion on the enzyme activity of invertase Introduction: Hypothesis: The activity of the invertase will be inhibited by the heavy metal ions Prediction made from the hypothesis: Biological principle: Heavy metal ions are non-competitive inhibitors. They do not compete with the substrates for the active sites of enzymes. They attach to other parts of the enzyme molecules and cause changes in the structure of the active site. The substrate molecules can no longer bind to the active sites and the rate of enzymatic reaction decreases. Therefore, they prevent the enzyme reactions from taking place.
