Dafna11 [192]

Answer:

Can grow on MM1.

Explanation:

  • Organisms that can only grow in a media having specific nutrients included in it are called a fastidious organism, this implies that these organisms have specific nutrient requirements for their growth.
  • MM 1 represents the minimal media which has basic nutrients present in it, however as the fastidious organisms require some particular or complex nutrients for their growth they can not grow on the minimal media.
  • Therefore, since the organisms that are given in the question is able to grow on the minimal media MM1, this implies that it is not a fastidious organism.

How did the frequency of stimulation affect the amount of force generated by the isolated skeletal muscle when the frequency of
Alexxandr [17]

Answer:

When the frequency of stimulation of a muscle increases -without it having the opportunity to relax- a process called summation (addition) occurs, promoting an increase in the generation of force in the isolated skeletal muscle.

Explanation:

Summation is a phenomenon that occurs as a consequence of the arrival of successive stimuli that produce the contraction of the skeletal muscle before it achieves its partial or total relaxation, between subsequent stimuli.

<em>When the summation occurs in the muscle, the force generated on it increases its magnitude proportionally to the number of stimuli received, maintaining the muscle contraction in time</em>.

Tetany is the prolonged contraction of a muscle in an abnormal way, by the summation of stimuli received , as some bacterial toxins can produce. The summation can be temporary -when multiple stimuli reach the muscle in a determined time- or spatial, when the amount of stimuli activates a greater amount of motor units.

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.
