A basic question about energy in our body..?
Hi,
How does having sugar in our blood(i.e. energy) help us in do activities(like moving our limbs,running,walking etc)? I mean, I am curious from a mechanical angle - how does the sugar finally gets converted to mechanical motion? or in another way, how is the energy needed for running, derived from blood?
Thanks
Answers:
Understanding fully the breakdown of glucose into energy (ATP) does take a bit of reading, but in simplest terms carbohydrates are broken down by digestion into simple sugars, i.e. glucose. The cells within our body then import the sugars inside (inability of diabetics ---> insulin helps the import of sugars inside of cells) and through different cellular processes in the cell energy is made. If you really want to get in depth read up on:
