How do you describe a Michaelis-Menten plot?

Michaelis-Menten kinetics describe the velocity of a reaction involving an enzyme and a substrate. The enzyme and the substrate bind together to form a complex in a reversible reaction. This complex can either dissociate to give back the enzyme and substrate, or could move forward to give the enzyme and a product.\nThe Michaelis-Menten plot describes how the concentration of the substrate can push the reversible enzyme-substrate reaction either forward or backwards. As the concentration of the substrate is increased, the rate of the forward reaction increases only until it reaches its maximum ..

What are some easy project topics in microbiology?

The first project requires a large plastic kitchen cutting board. Use a permanent marker to divide the board into six numbered sections. Rub the board thoroughly with luncheon meat, and allow it to sit overnight. The next day, fill five small numbered glass containers with five different household disinfectants and another with water (as the control). The student uses clean cotton balls dipped in the disinfectants to clean each section, making sure to match the numbers of the glass containers with the corresponding section of the cutting board. Let the board dry completely before swabbing each..

Which acid is present in nettles?

Various analyses about nettles reveal around 50 chemical constituents. The stinging nettle’s roots have undergone extensive studies and contain serotonin, choline, acetylcholine, histamine, two resins, sugar, albumen, gum and starch. In addition, homovanillyl alcohol, neo-olivil, secoisolariciresinol, scopoletin, steryl glyocosides, sterols and oleanol acid are present in nettles.\nThere are only a small number of studies that have been conducted on the seeds of the nettle plants. From those few studies, selenium, potassium, sodium, manganese, magnesium, phosphorous, calcium, copper, zinc, n..

What is the Kb of NaOH?

Ionization constants are numerical values that measure the extent by which water, acidic or basic compounds dissociate in a solution at equilibrium. The symbols for the ionization constants of water, acids and bases are Kw, Ka and Kb, respectively. The relationship between the three constants are mathematically represented by the equation Kw = Ka * Kb.Weak acids and weak bases do not completely ionize in a solution, hence their concentrations are difficult to determine. Typically, the Ka and Kb values of weak acids and bases range between 10-1 and 10-13.Strong acids and strong bases behave dif..

What is the difference between organic and inorganic matter?

Another difference between organic and inorganic compounds is organic matter will burn, but inorganic matter will not burn. Organic matter is found in living, or once-living, organisms, so it is biological in nature. Inorganic matter is generally obtained from non-living matter, so it is mineral in nature. Inorganic compounds are less complex than organic compounds. The presence of carbon prevents organic compounds from forming salts. Inorganic compounds can form salts and are readily soluble in water.\nOrganic matter has a slower reaction rate than inorganic matter. The slower reaction rate a..

How do you make a black light ladybug trap?

Legend says that finding a ladybug in the home brings good luck. Too many, however, can become a nuisance. Using a black light is an easy way to trap them for removal.Step 1: Prepare the bottleUse a wine bottle or plastic soda bottle to capture the ladybugs. A little residue is helpful in attracting them, as the bugs are drawn to the odor. Add 1 cup of water to the bottle.Step 2: Set up the black lightPlace the black light in an area of the room that will not be disturbed, such as behind a couch or chair. Soften the lights in the room by turning off the main lights and closing the curtains. Th..

Why is my second toe bigger than my big toe?

Morton's Toe is a variation observed in 10 to 20 percent of the population, according to About.com. It can lead to foot pain and other problems due to increased pressure on the second toe while walking. This pressure may lead to the development of a callus on the ball of the foot. The toebox of a shoe may put pressure on the second toe, leading to bruising and black toenail. Finally, Morton's toe can cause the foot to rotate inward excessively, which is referred to as overpronation.\nAbout.com advises that finding the right pair of shoes is important to help with foot problems associ..

How are a diamond's dimensions measured?

Round cut diamonds are measured directly across the center, with the second measurement at a 90-degree angle to the first. Even the best cutters rarely produce a diamond that is truly round. They come close, as in this example measurement of 6.67 by 6.65 by 4.01 millimeters. The last figure is the height.\nThe near-perfect measurement seen above means this diamond has good symmetry, and the cut stone has the best light refraction, creating more "flash." To be considered a proper cut brilliant diamond, it must be within certain limits. For example, a 0.5-carat diamond must have no more than a 0..

How are radio waves detected?

Antennas that receive radio signals are generally the same size as the wavelength they are designed to receive. Wider antennas detect longer, or fainter, wavelengths. Communications antennas are usually one-quarter the size of the transmitter, especially with applications for automobiles, satellite television and cellular phones. Receiving antennas are smaller simply to save space while the transmitters are stronger so detection is easier.\nIn March 2014, the Niels Bohr Institute announced a new method to detect radio waves using lasers that operate at room temperature. Very low frequencies of..

What is a nasal passage?

These membranes trap substances such as dust and bacteria as an individual inhales them. Having entered the mucous membrane in the nose, these substances safely travel into an individuals gastric juices where they are not as harmful. These tiny cells ensure that dust and similar small particles do not enter an individuals respiratory system and cause health problems. The nasal passage also contains small patches of tissue called olfactory membranes, which are responsible for an individuals sense of smell. When air rushes past the olfactory membranes, a scent is transmitted to an individual, wh..
