The correct answer is option 4, that is, muscle cells require more energy, so they have more mitochondria in comparison to the skin cells.
Mitochondria are the powerhouse of the cells. The synthesis of ATP takes place in them, that is, the energy currencies of the cell. The cells of the muscles need to work hard and thus require ample energy, for this, they need more concentration of mitochondria to generate a high energy yielding ATPs.
Answer:
1. The reason there is energy released in the process is because the products formed (ADP and hydrogenphosphate/phosphate) have stronger covalent bonds (plus intermolecular forces with the surrounding solution and dissolved ions) than the starting materials.
2. The end product of oxidative phosphorylation is ATP and water. ATP synthesis is coupled with the transfer of electrons to O2, which combines with protons to form water. Phosphorylation is the chemical addition of a phosphoryl group (PO3-) to an organic molecule. The removal of a phosphoryl group is called dephosphorylation. Both phosphorylation and dephosphorylation are carried out by enzymes (there are enzymes involved). kinases and phosphatases, From the family of Enzymes.
Answer:
The formation of magnesium chloride, MgCl2, is another example of ionic bonding. When magnesium reacts with chlorine, a magnesium atom loses two electrons and becomes a positively charged ion, Mg2+. At the same time, two chlorine atoms gain one electron each and become negatively charged chloride ions, Cl−.
