Cellular respiration is a metabolic pathway that breaks down glucose and produces ATP. The stages of cellular respiration include glycolysis, pyruvate oxidation, the citric acid or Krebs cycle, and oxidative phosphorylation.
During cellular respiration, a glucose molecule is gradually broken down into carbon dioxide and water. Along the way, some ATP is produced directly in the reactions that transform glucose. Much more ATP, however, is produced later in a process called oxidative phosphorylation. Oxidative phosphorylation is powered by the movement of electrons through the electron transport chain, a series of proteins embedded in the inner membrane of the mitochondrion.
These electrons come originally from glucose and are shuttled to the electron transport chain when they gain electrons.
As electrons move down the chain, energy is released and used to pump protons out of the matrix, forming a gradient. Protons flow back into the matrix through an enzyme called ATP synthase, making ATP. At the end of the electron transport chain, oxygen accepts electrons and takes up protons to form water. Glycolysis can take place without oxygen in a process called fermentation. The other three stages of cellular respiration—pyruvate oxidation, the citric acid cycle, and oxidative phosphorylation—require oxygen in order to occur. Only oxidative phosphorylation uses oxygen directly, but the other two stages can't run without oxidative phosphorylation.).

Your answer will be B.
Explanation:
Earthquakes are the result of released energy from tectonic plates rubbing against each other on active fault lines.

<span>Now that franks in my body, my non-specific immune responses will automatically target him. once my white blood cells notice him they'll begin their counterattack. the basophils in my bloodstream will release a chemical substance called histamine. Histamines cause inflammation and increased blood flow. This brings neutrophils and monocytes to the site. Neutrophils are attracted by inflammation and infection. Like basophils, they, too, contain granules filled with powerful chemicals that are released when they encounter foreign invaders. They can also gobble up these antigens and kill them before they enter the bloodstream.</span>
