Cellular respiration is the metabolic reaction inside the cell to convert chemical energy into ATP. Biomass is the total mass of organisms at a trophic level.
<h3>What is exothermic reaction?</h3>
The type of reaction in which releases energy after its completion.
- Cellular respiration releases energy because it is an exothermic process in which energy is released as a by-product of the reaction.
- Organisms are larger in size at higher trophic levels, but their smaller numbers result in less biomass.
Thus, being exothermic in nature, cellular respiration releases energy and because of less numbers, there is less biomass at high trophic levels.

Answer:
Explanation:
HCl is produced by the parietal cells of the stomach. To begin with, water (H2O) and carbon dioxide (CO2) combine within the parietal cell cytoplasm to produce carbonic acid (H2CO3), which is catalysed by carbonic anhydrase. Carbonic acid then spontaneously dissociates into a hydrogen ion (H+) and a bicarbonate ion (HCO3–).
The hydrogen ion that is formed is transported into the stomach lumen via the H+– K+ ATPase ion pump. This pump uses ATP as an energy source to exchange potassium ions into the parietal cells of the stomach with H+ ions.
The bicarbonate-carbonic acid buffer works in a fashion similar to phosphate buffers. The bicarbonate is regulated in the blood by sodium, as are the phosphate ions. When sodium bicarbonate (NaHCO3), comes into contact with a strong acid, such as HCl, carbonic acid (H2CO3), which is a weak acid, and NaCl are formed. When carbonic acid comes into contact with a strong base, such as NaOH, bicarbonate and water are formed.
The bicarbonate ion is transported out of the cell into the blood via a transporter protein called anion exchanger which transports the bicarbonate ion out the cell in exchange for a chloride ion (Cl–). This chloride ion is then transported into the stomach lumen via a chloride channel.The respiratory system contributes to the balance of acids and bases in the body by regulating the blood levels of carbonic acid
Chloride ions are important in neutralizing positive ion charges in the body. If chloride is lost, the body uses bicarbonate ions in place of the lost chloride ions. Thus, lost chloride results in an increased reabsorption of bicarbonate by the renal system.
<span>Meiosis is the process of cell division that reduces the chromosome number by half. During the process two phases (two nuclear divisions) occur: Meiosis I and Meiosis II. Meiosis I is the phase of reduction and Meiosis II is the division. So, if a cell under a microscope shows two daughter cells and they aye haploid than this is the stage Meiosis II, in which the cell is divided into two daughter cells.</span><span />
