Albert von Kölliker was the first researcher to isolate mitochondria, which are A) the structures in the center of cells that co
ntain the DNA that governs all aspects of the cell's structure and function. B) the structures within cells that generate energy for fueling cellular processes. C) foreign proteins that cause the immune system to create an antibody. D) nutrient-rich materials that provide cells everything they need to grow.
Mitochondria are membrane-bound cellular organelles that are found in eukaryotic plant and animal cells that produce high energy compounds (called ATP) that are responsible for cellular activities.
NOTE: ATP (adenosine triphosphate) is described as the unit for energy in biology, hence the answer is B
