I have no clue on what you are talking about
Well in my words, The vaccine is the weakened or dead version of the virus(pathogen). This actually prepares the body to be un-affected if it ever comes in contact with the virus (pathogen) again. After the vaccine is injected your body produces memory cells. These help your body become immune to the same virus (pathogen) twice. So basically it helps protect your body from dangerous viruses or pathogens, and develops immunities against them.
I really hope this helped :D
The right answer is 1.
We will consider here the catabolism of a glucose molecule by glycolysis and the Krebs cycle, without taking into account the associated pathways.
* Assessment of glycolysis: formation 6 ATP in theory (5 ATP actually).
* Assessment of the catabolism of pyruvate: formation of 3 ATP per molecule of pyruvate in theory (2.5 in reality) and therefore of 6 ATP in theory (5 ATP in reality) for a molecule of glucose.
* Review of the Krebs cycle (associated with ETS reactions) : theoretically 12 ATP per molecule of acetylcoenzyme A (10 ATP in reality) and thus in theory 24 ATP (20 ATP actually) for a molecule of glucose.
The overall theoretical balance is therefore 36 ATP (some books says 38) (30 ATP actually).
