Glycolysis results in a net gain of 2 ATP. Aerobic respiration results in 36 - 38 ATP.
Glycolysis. In fermentation, glycolysis is the primary means by which energy is created. In cellular respiration, glycolysis creates pyruvic acid, which then enters the mitochondria and is further processed to create more ATP. Note, glycolysis is not a very efficient means of creating ATP (the primary source of energy in cells). Glycolysis only creates two ATP, while cellular respiration can create as much as 38.
For cellular respiration two ATP must be put into glycolysis which starts the whole process of cellular respiration Steps: 1. Glycolysis 2. Transition Stage 3. Kreb cycle 4. Electron Transport Chain (ETC)
Starting with Glycolysis, 2 ATP are required to start. 4 ATP are produced by the end of Glycolysis, with a NET ATP of 2.
Without oxygen - only glycolysis occurs. This results in very few ATP molecules. With oxygen, all of celluar respiration occurs and this results in almost 40 ATP molecules. So, oxygen is essential to the production of mass ATP molecules.
cellular respiration is pretty much the opposite of photosynthesis..i think.

Glycolysis alone only nets you two ATP. Cellular respiration will net you an additional 34-36 ATP.

GLYCOLYSIS and it only produces 2 ATP
Cells can release energy in two basic processes: Cellular respiration and fermentation. Cellular respiration requires oxygen but fermentation does not. Cellular respiration releases MUCH more usable energy then fermentation does.
Aerobic Respiration
There are anaerobic and aerobic types of cellular respiration. Anaerobic (including glycolysis) respiration does not involve oxygen. Aerobic (including the Kreb's, or citric acid, cycle and oxidative phosphorylation) respiration requires oxygen, and generates much more energy than anaerobic respiration.

Because enzymes act as barriers in reactions making it more prone from sickness.... welcome

Anaerobic cellular respiration generates a net gain of 2 ATP. Aerobic cellular respiration generates 36 to 38 ATP.
