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.

A contractile vacuole will help this organism better survive in its moist environment by <u><em>preventing or stopping the cell from absorbing too much water from its moist environment.</em></u>

<u><em /></u>

<u><em /></u>

  • A contractile vacuole is an <em>organelle</em> that can be found in organisms that are said to be <u><em>single-celled (Unicellular organisms).</em></u>

  • One of the primary functions of a contractile vacuole is to absorb <u><em>excess water</em></u> from the protoplasm in the unicellular organism and release this water to the surrounding environment.

  • A contractile vacuole can be called the excretory organ of unicellular organisms. This is because it is involved in <u><em>osmoregulation.</em></u>
