The sarcomere shortens when the myosin heads of the thick filaments, in a cocked position, form cross bridges with the actin mol
Artyom0805 [142]

Here are the steps;

step 1. The activated myosin head binds to actin, forming a cross bridge.

Step 2. ADP is released and myosin slides the thin filament toward the center of the sarcomere.

step 3. ATP binds to the myosin head and detaches it from actin

step 4. ATP is hydrolyzed to ADP and P(i) and the energy released re-elevates the myosin head.

How many ATP are generated in the electron transport chain?<br> оооо<br> 2<br> 4<br> 32<br> 36
Svetllana [295]

Answer:

32 ATP <em>molecules are generated in the </em><em>electron transport chain.</em>

<em><u>Explanation:</u></em>

The cell used a process known as Chemiosmosis and to produce ATP. The energy released from the <em>electrons during the electron transport system and they pump the protons.</em> The energy is transferred into higher energy bond of ATP and they are made to perform their cell work.

<em>'Electrons are the subatomic particles that orbit the nucleus of an atom'. They are always negative in charge and are always smaller than the 'nucleus of the atom'.</em> The electron transporters are arranged in series and they are embedded into their inner mitochondrial membrane and they are shuttles the electrons from '\mathrm{NADH}^{\prime} and '\mathrm{FADH}_{2}' to the molecular oxygen. In this process, the protons are pumped through the 'mitochondrial matrix' to 'the intermembrane space' and the oxygen level is lowered to form the water.
