Explain why hydrogen peroxide would be more effective as a disinfectant on inanimate surfaces as opposed to living tissue?
Hydrogen peroxide serves as a good disinfectant as it produces peroxide free radicals which can interact with inanimate chemical compounds to produce different compounds.
Living organisms are also affected by hydrogen peroxide as it can denature macromolecules present on their surface.
But, living organisms are equipped with special organelles known as peroxisomes which can neutralize hydrogen peroxide.
Hence, living organisms can exhibit moderate tolerance to hydrogen peroxide.

Q1: Define the difference between an antiseptic and a disinfectant. Q2: Why is the disk diffusion method a viable method for determining the effectiveness of a disinfectant? Q3: Gram negative and gram positive organisms tend to have different sensitivities to the same disinfectant. What would explain this? Q4: 100% ethanol is less effective than 70% alcohol. Why?
what are three (or more) reasons why you would want to filter-sterilize something as opposed to heat sterilize it?
Explain how you would prepare each of the following solutions,
using liquid stock hydrogen peroxide as the solute and saline as
the solvent
Section 3 Drug Dosage Calculations Review Set 27 plain how you would prepare each of the following solution as the solute and saline as the solvent. 1. 480 mL of strength for wound irrigation
Describe the principles of vaccination and/or immunization. When would it be more effective to inject a modified toxin, as opposed to a cell or virus, as the content of the vaccination?
I got the correct answer but I need short and clear
eplaination why that was the correct answer
22 Which of the following statements is TRUE of disinfectants? A) They are effective in destroying endospores. B) They are used on living tissue. C) They are used for sterilization. VD They are used on inanimate surfaces. E) They are only effective for short periods of time (seconds to minutes). 49 The therapeutic range of an antimicrobial is the A) ratio of...
*Why are alpha particles more effective than betas for causing tissue damage, but x-rays and gamma rays are equally effective (that is for each joule of energy deposited by radiation in a kg of tissue, why alpha particles do more damage than betas, but gamma rays do an equal amount of damage.) This was from class only.
Explain what a monopolist must do in order to sell more as opposed to how this would happen under perfect competition. Under what scenario could and would a monopolist go out of business?
1.explain why there are more lines in the hydrogen emission spectrum than in the absorption spectrum? 2. indicate asborption, from a lower energy level to a higher energy level. Then indicate emission for the same transition as through various pathways, which would then result in many more emission peaks than there was in the original absorption (transition).
In this experiment we are testing the effect of different chemical concentrations on microbial growth. Let’s say instead we used a 1.0% solution of Bleach against a low, medium, and high amount of microbes. How would you expect the growth numbers to look in this experiment? In restaurants, most food contact surfaces are smooth and lack cavities/pores in their surface. What is the advantage of that for microbial control? If soaps are not powerful at killing microbes, why are they used...
Considering the trends in ionization energies, would you expect sodium or potassium to be more reactive? Explain. Considering the trends in atomic radii, would you expect cesium or radon to have the larger radius? Explain. Compare the ionization energies of sodium and rubidium and then compare the electron affinities of chlorine and iodine. Which of the following chemical combinations of the elements would be the most exothermic - Na and Cl, Na and I, Rb and Cl, or Rb and...
