The Tubes

graduated cylinder measuring about 4-ml. Transfer the glucose form the graduated cylinder to a test-tube. 5. Then do the same thing for the sucrose using a different beaker, and test-tube. 6. Then wash the beaker, the stirring rod, and the graduated cylinder. 7. Add about 5cm3 of benedict’s solution to a small amount of sample in the glucose test tube. But before you add benedict’s solution to the test tube with sucrose in it add hydrochloric acid to the sucrose to break it down to fructose and…

test tube holder Labels Marker Procedure First take 5 test tubes and label them from 1 to 5. Label the test plate from 1-5. Set up 5 water bath to 10 °C . Add 5 cm3 of starch solution into the 5 labeled test tubes. Add 5 cm3 of amylase enzyme into other 5 labeled test tubes. Put one of the starch solution test tube (preferably the one labeled 1) and one of the test tube containing amylase into the water bath (10 °C). Do the same for the other test tubes. Let the test tubes not be disturbed…

far off from what we think it to be and what we consider it to be ideal (you tube, n.d.). It’s time Americans wake up and face reality, because the reality is that the top 1% of Americans have so much money that is beyond believe. 1% of the wealthy Americans own stocks, bonds and mutual funds and the bottom 50% of Americans own ½ of a 1% of the investments which means most Americans are scraping scrapes to survive (you tube, n.d.). A CEO of a company does not need to work as hard as an average…

five different tubes. Next, I placed three drops of iodine solution into each tube. Then, I observed the result, if it changed color to brown then dark purple or black, it contained starches. Solutions two, four, and five had a positive result for polysaccharides. After that, I preformed the Biuret test, which sees if a substance contains proteins. I first placed 5 drops of each stomach content into the appropriately labeled tube. Next, I added one drop of Biuret solution into each tube. Then,…

Introduction Catalysts speed up the rate of a reaction without being consumed in the process4. Enzymes are proteins that act as catalysts to a given biochemical reaction4. Enzymes manage to expedite metabolic reactions by lowering the activation energy required for the reaction to proceed4. In ideal conditions, the reactant macromolecule binds and acts on what is referred to as a substrate. However, enzymes require specific conditions specific conditions to perform most effectively4. Enzymes are…

help identify an unknown microbe. For the first part of this experiment, a dichotomous key (attachment 1) was created using the information of possible microbes for the unknown as provided by the instructor. The student was then given an agar slant tube containing the unknown #4 microbe to use throughout the course of the experiment. Identifying the shape and whether the microbe was gram negative or positive was done by performing a gram stain and viewing it with a microscope. The stain…

results in change in the shape of red blood cells. How it occurs: Red blood cells are flexible due to which they can easily pass from the delicate tubes called capillaries. When they change their shape from the normal pattern, they may clog in the capillary tubes and cannot from it. Due to this blockage of capillary tubes oxygen cannot pass through the tubes properly…

Determination of fat in milk AIM: - To determine the fat content by using gerber method. Principle: - The milk is mixed with sulphuric acid and iso-amyl alcohol in a special Gerber tube, permitting dissolution of the protein and release of fat. The tubes are centrifuged and the fat rising into the calibrated part of the tube is measured as a percentage of the fat content of the milk sample. Apparatus: - Butyro meter, 10.75ml pipette,amyl alcohol, stoppers, gerber centrifuge, water bath.…

indicators can be performed to test the presence of various macromolecules. Procedure 1) Using a sharpie and a ruler, mark 4 test tubes to the 2 cm mark (from the bottom). Label each test tube with the group name and the name of test solution. Do this on top of test tube so the bottom is clear for viewing colour change. For each macromolecule test, fill test tubes with 2 cm of testing…
