Answer:
c. the high-energy phosphates stored in muscle cells
Explanation:
Phosphocreatine (PC) or creatine phosphate is a compound rich in energy. It has energy stored in it which can be used to phosphorylate ADP into ATP. The phosphocreatine is stored in muscle cells when muscles are not working. The produced ATP serves as an energy source for muscle contraction. The creatine produced during ATP production is phosphorylated again into PC using ATP when muscles are resting.
Astronomers have seen stars forming within a nebular cloud. As the nebular cloud condenses and its own gravitational attraction collapses it, heat and energy build up creating a planet.
D a wolf’s sense of smell.
Cell walls are thicker than cell membranes, and can therefore support the cell well. They keep a strong boundary for the protection of the cell, but can let water and some nutrients through to nourish and power the cell. Hope this helps! :)
