In the micro-world of cells, biological motors perform a multitude of tasks such as muscle contraction. But how do these ...

Just like the proteins in our muscles, which convert chemical energy into power to allow us to perform daily tasks, these tiny rotary motors use chemical energy to generate force, store energy ...

The products do not contain stored chemical energy which can be used in respiration. Mammalian muscle: lactic acid. Yeast: ethanol and carbon dioxide. Some plants: ethanol and carbon dioxide.

In most animal cells, adenosine triphosphate (ATP), a compound with high potential energy, works as the main carrier of chemical energy ... Between meals, cardiac muscle cells meet 90% of their ...
