Which correctly compares the immunity produced by a vaccine with the immunity produced by injection of antibodies from an extern

al source? Injection of antibodies helps the body develop memory cells, which only produces a temporary immunity, whereas a vaccine can fight infection for years. A vaccine helps the body develop memory cells that make immunity last, whereas injection of antibodies only produces a temporary immunity. Injection of antibodies helps the body develop its own copies of the antibodies so immunity lasts, whereas a vaccine only produces a temporary immunity. A vaccine actively attacks pathogens until it is used up so immunity is temporary, whereas injected antibodies will remain passively in the blood, giving immunity for life.

If the atp synthase for an organism contains 15 c subunits, how many protons must flow through atp synthase per each new atp tha
anastassius [24]

Each time a new ATP is created, ATP synthase must process 5 protons.

<h3>Where is ATP synthase found and what does it do?</h3>
  • ADP and phosphate are converted into ATP by the mitochondrial enzyme ATP synthase, which is located in the inner membrane.
  • Protons are transported over a gradient created by electron transfer from the chemically positive to the negative side of the proton, which drives the flux of protons.
<h3>How does photosynthesis's ATP synthase function?</h3>
  • The light-driven production of ATP is catalyzed by the chloroplast ATP synthase, which is activated in the light and deactivated in the dark by redox-modulation via the thioredoxin system.
  • This down-regulation is thought to be crucial for minimizing wasted ATP hydrolysis at night.
<h3>What makes ATP synthase so crucial?</h3>

All cellular functions are powered by ATP, which is constantly used by cells and required for production. About 100 ATP molecules can be produced by each ATP synthase every second.

Answer:

As the wave moves to and fro so the total distance will be d=2x5=10 m

we have

time (t) = 5 s

hence velocity will be =2 m/s
