Can cellular respiration mean eating?
Cellular respiration is a way to convert sugars (ex. glucose) into usable energy; and yes, this comes from eating, but it isn’t the same as the concept “eating”. Eating is the consumption of food itself, where cellular respiration is the process in which the nutrients for food is converted to energy. Though eating and cellular respiration are different concepts, you need to eat so your cells can perform cellular respiration. Here is how eating and cellular respiration are tied together; let’s say you ate a sugar cube (sucrose): 1.) The sugar cube, made of let’s say…sucrose, is broken down during digestion, particularly by the enzymes in your saliva. The enzyme amylase breaks down starches, including your sucrose, into simpler molecules (in this case, glucose and fructose.) 2.) You swallow the sugars, and they end up in the stomach and later in the small intestine, where it is absorbed by the villi. The sugars then end up in the blood, and they are transported to the cells.
