Enzymes are catalytic proteins that speed up chemical reactions by lowering the activation energy of the reaction. our body cells depend highly on enzymes to complete many important functions‚ such as digestion and metabolism. Enzymes are selective‚ in which each enzyme can only speed up a specific reaction. There are molecules that enzymes work with called substrates. substrate bind to an area of an enzyme called active site. There is specificity between the enzyme and substrate that react with

During all this‚ concentration camps were being made. A concentration camp is a place where large numbers of people‚ especially political prisoners or persecuted members of a minority‚ are imprisoned in a small area with inadequate facilities‚ sometimes to provide forced labor or to await mass execution. Many of these concentration camps later became death camps for Jews. One of the most infamous concentration camps was Auschwitz because it was the largest of all concentration camps. In these

The Bouncy Egg Experiment! Mrs. Murosky December 19‚ 2013 Introduction: GOAL: The goal of this experiment is to get an egg to bounce. WHY IS THIS IMPORTANT? : The results of the egg experiment is important because it shows what the membrane of an egg looks like‚ but allows the experimenter to have fun in the process. LITERATURE: The acids in the vinegar make the shell deteriorate. Eggs contain "calcium carbonate"(this is what makes it hard)‚ and vinegar is an acid. When they both combine

Are naked eggs with no shell? What? You may think I am speaking about a hard boiled egg‚ but‚ no. Boiled eggs have their centers heated making the shell easily come off. Naked eggs have their shells taken off with one simple ingredient everyone has. Vinegar. The vinegar acid inside the vinegar strips the shell away from the egg. The vinegar solutions dissolves the shell from the egg. Once the egg has been separated form it’s shell the only thing keeping the liquid goo inside is the thin‚ flexible

Egg Osmosis Lab Introduction What is osmosis? Osmosis is a very important part of biology. It is the spontaneous passage of water or other solvents through a semipermeable membrane. A semipermeable membrane is one that blocks the passage of dissolved substances. Osmosis occurs when there is an imbalance of solutes outside of a cell versus inside the cell. A solution that has a higher concentration of solutes than another solution is said to be hypertonic‚ and water molecules tend to diffuse into

(If ingested in undiluted form‚ it has a severe drying effect on mucous membranes of mouth and throat.) NEVER MAKE AN UNCONSCIOUS PERSON VOMIT OR DRINK FLUIDS. Wash out mouth thoroughly‚ and give plenty of water to drink. Do not induce vomiting. Get medical attention immediately. ii. Inhalation exposure

equalizing the concentrations on each side of the membrane. Diffusion is the spreading of something more widely.During the osmosis and diffusion lab I tested what happens to a fresh egg when osmosis and diffusion across membranes. The eggs were placed in vinegar‚ distilled water‚ and then lastly syrup. The eggs were weighed every day to see if they got heavier or lighter. My hypothesis is that the eggs will absorb the contents it’s placed in and will become heavier. First‚ the fresh hen’s eggs were placed

introduction to enzymes Enzymes are the foundation of energy and the life force in all living things. They are responsible for building‚ detoxifying‚ and healing the body. They are also the force that allows your body to digest and absorb food. Enzymes also regulate tens of thousands of other biochemical functions that take place in the body every day. Without enzymes‚ seeds would not sprout‚ fruit would not ripen‚ leaves would not change color‚ and life would not exist. Therefore‚ the study of enzymes has

Title: Enzyme Activity Aim: To investigate the activity of the enzyme catalase in liver and potatoes‚ and to investigate the effect of temperature‚ surface area‚ pH and certain chemicals on the activity of catalase. Equipment: Dilute hydrochloric acid solution x 1ml 10 volume hydrogen peroxide x 100ml Copper sulphate solution x 1ml Aluminum nitrate solution x 1ml Zinc nitrate solution x 1ml dilute NaOH solution x 1ml Mortar and pestle x 1 25ml Beaker x 1 Hot plate x1

This experiment was performed in order to analyze the effects of pH‚ enzyme concentration‚ and temperature on the catalytic rate on enzyme ALP. The initial experiment was done to approximate the optimum pH for the activity of the enzyme. The hypothesis was that alkaline phosphatase activity will be critically affected by pH effects. The hypothesis was valid because the data shows that the pH values for the acidic‚ basic‚ and neutral tubes increased over time‚ absorbing at similar rates. The basic
