Expert Solution

We eat food which is complex in nature. Our digestive system breaks down complex food into simpler ones such as glucose. This mainly occurs in the small intestine which is supplied with villi or finger-like projections specifically to increase the surface area of absorption. Glucose comes in the blood to be circulated so that it may be transported to every cell. Facilitated diffusion favours the glucose entry into the cells where glucose undergoes oxidation by a complex process which forms ATP as the energy currency of the cell. Glucose reach cells through capillary fenestrations or perforations located on the walls of the capillaries. The small size of the glucose permits them to be filtered out of the capillaries through the fenestrations. Thus the whole process is complex but the intention is simple that is to make and give life. In the absence of any of the processes, there would be no life.

Researchers studied the relationship between glucose concentration, oxygen level, and ATP production in one type of mammalian cell.

Researchers studied the relationship between glucose concentration, oxygen level, and ATP production in one type of mammalian cell. Cells were isolated and cultured in growth medium containing either 1.5mM glucose or 25 mM glucose and at oxygen levels that varied from 0% to 21%. The researchers determined the concentration of ATP per cell under the different conditions. The ATP concentrations are shown as relative to the maximum ATP concentration obtained when cells were cultured in the presence of 25 mMglucose and 21% oxygen, standard culture conditions. The data are...
