The purpose of this reaction is to break the bonds between the six carbon atoms of glucose, resulting in six carbon dioxide molecules, to move hydrogen atom electrons from glucose to oxygen, forming six water molecules, and to capture most of the free energy released in the form of ATP. The first step in Cellular respiration is Glycolysis. Glycolysis breaks down glucose in the cytoplasm into two molecules of pyruvate. Several enzymes are required in this steps. Two energy-rich ATP start the process. At the end of the process, there are two pyruvate molecules, four ATP, and two NADH. Cells that use oxygen uses pyruvate in a second process that creates more ATP. The second step in Cellular respiration is Link Reaction (pyruvate oxidation). In Link Reaction the pyruvate is transferred into the mitochondria. Pyruvate oxidation occurs in the mitochondria. In the process, a CO2 portion is cleaved from pyruvate and removed from the cell as waste. This acetyl compound combines with an enzyme called Coenzyme A to form acetyl-CoA. The third step is the Kreb Cycle. Acetyl CoA combines with oxaloacetate to form a molecule with six carbon atoms. This …show more content…

Carrying capacity is dynamic since environmental conditions are always changing. Many biotic and abiotic systems play a role in determining the carrying capacity, such as food, water, materials, weather, other species, and habitat. The population of rabbits depend on majorly on food and predators. If a rabbit population is placed in an environment that is abundant and has no predators, the population will increase exponentially. Until it reaches a point which the environment can no longer sustain the population. Then the population will start to die. This sudden increase in population could damage (lower) the biocapacity of the environment as the environment lost some of its regenerative
