Bacteria need an optimum temperature for their growth, so this is the reason why we might not see as much bacterial colonization of microbes from human saliva on plates cultured at 25 °C versus plates incubated at 37 °C.

Why do bacteria only grow at certain temperatures?

  • The main justification for incubating bacterial cultures at various temperatures is that different temperatures favor the growth of particular bacteria.
  • Most infections and typical ambient bacteria are classified as mesophiles, which thrive in temperatures between 20 and 40 degrees Celsius.
  • An optimum temperature is required for the enzymes to show their activity, and for the division also many enzymes are involved in the process. So, the bacterial culture can be seen at a particular incubation temperature only.

Imagine that a toxin is introduced to the body and inhibits the establishment of the proton gradient in the intermembrane space.
jarptica [38.1K]

Answer:

ATP synthase would be unable to produce ATP

Explanation:

ATP synthase depends on the proton gradient in the intermembrane space to enable it to produce ATP. As a consequence of this, the toxin will make it inactive. Oxidative phosphorylation is now inhibited in this case, as opposed to substrate-level phosphorylation.

Pyruvate is a product of glycolysis, and it will not be affected by a toxin. NADH is very important in the establishing of a proton gradient, so it is expected that it would be unable to be oxidized due to the toxin. Protons produced in the conversion of NADH to NAD+ actually establish the proton gradient. If the gradient is absent, NADH is then not likely to be oxidized.

docker41 [41]

Answer:

placing the client in the side lying position in bed

Explanation:

Based on the scenario being described within the question it can be said that the the most appropriate nursing action would be placing the client in the side lying position in bed. This is the best action in this scenario as it will help the individual drain the secretions that may otherwise cause aspiration pneumonia which is a lung infection that develops after you inhale liquids or vomit into your lungs.
