All living organisms require energy for their life processes. The way they obtain this energy is via the process of cellular respiration. Cellular respiration is the metabolic (catabolic) reaction in which cells break down food molecules to release energy by combining glucose and oxygen. Cellular respiration can either be aerobic (with oxygen) or anaerobic (without oxygen). Aerobic cellular respiration involves three main stages viz: Glycolysis, Kreb's cycle and Oxidative phosphorylation.
The Oxidative phosphorylation of aerobic respiration further includes the Electron transport chain (ETC), which is a series of electron transfer in order to build a pump that will facilitate the synthesis of ATP (energy molecule). In a nutshell, after the ETC, 38 and 36 molecules of ATP are produced in prokaryotes and eukaryotes respectively.
The overall equation of aerobic cellular respiration is:
The carrying capacity in the container when compare to the
yeast population at hour 16, it has reached carrying capacity however the waste
produced by the yeast has begun to damage or kill the yeast cells. It will
reach its maximum and will slowly begin to drop off after the point.
