Why might it be easier to determine the bacterium that caused pneumonia than one that caused a wound infection?

#Unit 4. Cell Communication and Cell Signaling

  1. There are very few microorganisms that can cause pneumonia, while there are many that can cause wound infections.

  2. Bacteria that cause pneumonia can be identified with few tests. Many bacteria are normally found on the skin and may be in the wound complicationg indentification of the pathogen.

  3. We have much better tests for bacteria in the lungs than we do in wounds.

  4. The techniques of 16S rRNA sequencing are easier to perform on a sample taken from the lungs than a sample taken from a wound.

Some of the statements regarding competitive inhibition are given below
a)  The effect of a competitive inhibitor depends on the inhibitor concentration, the substrate       concentration and the relative affinities of the substrate and the inhibitor for the enzyme.
b) if the substrate concentration is low, the degree of inhibition will be great.
c) the substrate concentration is high, then the degree of inhibition will be marked low
d) non-competitive inhibitor can combine with an enzyme molecule to produce a dead-end complex
