B. all eukaryotic cells
hoped this helped!
One species eventually changes into something completely different over the course of millions of years. This can be described using the evolution theory. The evolutionary process of species shows how one population of a species changes over time to the point where that population is distinct and can no longer interbreed with the parent population. Hence one species is changed into another over o period of time. Speciation is an evolutionary process by which a new species comes into being.
This theory of evolution was proposed by Charles Darwin.
Answer;
ADP
Explanation;
-ATP molecule actsas the major energy molecule used by the cells. ATP synthase located in the inner membrane of the mitochondria, catalyses the formation of ATP, as a result of protons concentration gradient.
-The enzyme generates ATP from adenosine diphosphate and an inorganic phosphate through a process called oxidative phosphorylation, which is the process by which enzymes oxidize nutrients to form ATP.
