Design an experiment in which you will test the effect of an acidic fluid on enzymatic activity. Recall: enzymes are proteins!
pH ( increase in the hydrogen ion concentration
considerably influences the enzyme activity. if relation considered
between pH and enzyme activity it will give a bell
shaped curve normally. Each enzyme has optimum pH at
which the velocity is maximum. most of the enzymes of higher
organisms show optimum activity aroumd neutral pH (6-8)
but spme exceptions like pepsin (1-2), acid phosphatase (4-5) and
alkaline phosphatase (10-11).

Design an experiment that would test the effect of removing heat energy from a slightly stretched rubber band. You will not perform this experiment, but the materials you intend to use should be ones you would normally find at a college. Include in your design: A list of the materials required. A brief description of the procedure you would use (a diagram might be useful). The observations you would expect to see. Explain these observations in terms of both free...
Experiment 2 – The effect of temperature on the activity of catalase In this lab you will determine the effect of temperature on catalase activity Materials Yeast Measuring spoon 2 clean test-tubes hydrogen peroxide solution 10 ml graduated cylinder 2 balloons 1 beakers Permanent marker and tape / wax pencil stopwatch or timer crushed ice in a beaker/bowl Thermometer Procedure With a permanent marker, label tubes 1- 2. Fill each tube with 10 ml hydrogen peroxide. Place tube 1...
1. In the following experiment, you will test the effect of two different growth factors on the growth of your three cell lines. Please describe an experimental design with appropriate negative controls. Remember a negative control is one that does not have the substance for which you are testing. For example, if you were testing the effect of a fuel additive on your car's gas mileage, a negative control would be a measurement of the gas mileage without using the...
Replication in prokaryotic and eukaryotic cells involves enzymatic processes which join nucleotide sequences. Please explore the enzymes / proteins which are conserved in both prokaryotes and eukaryotes replication process.
Which of the following molecules can exhibit enzymatic activity? (a) amino acids and proteins (b) proteins and RNA (c) RNA and aminoacids (d) DNA and proteins (e) Lipids and proteins
1. design a follow-up experiment to investigate the enzyme peroxidase from plants. 2. investigate the effect of pH on enzyme activity.
Imagine you do a version of the Beadle-Tatum experiment in which you attempt to test the one-gene, one-enzyme hypothesis, but using the pathway of synthesis of amino acid Q from X (below). The reactions, in order, are catalyzed by enzymes E1-E5. X is always present in cells, and cells need Q to grow. E1 E2 E3 E4 E5 - xty 2 z 3 photo You identify a mutant strain that doesn't grow in normal medium, but does grow in medium...

Allosteric modulators give rise to sigmoidal V) vs. [S] kinetic plots C. A modular may either inhibit or activate an enzyme D. Binding of the modular changes the conformation of the enzyme molecule

For a behavior experiment, you want to test the effect of injected GABA. How much of a 2x10-4 M GABA solution do you have to inject into a 60 g crayfish to reach a concentration of 10-5 M in the hemolymph of the crayfish?
