Solution
The correct option is C Glycolysis
Cellular respiration is the pathway of yielding energy in the form of adenosine triphosphate (ATP). Both eukaryotic and prokaryotic cells undergo cellular respiration. Depending upon the oxygen demand, cellular respiration is of two types- aerobic and anaerobic respiration.
The liberation of energy during cellular respiration is due to the breakdown of glucose through a series of reactions, collectively known as glycolysis. Cellular respiration always begins with glycolysis, which can occur either in the absence or presence of oxygen. Aerobic respiration is the type of cellular respiration that proceeds in the presence of oxygen whereas, anaerobic respiration is the type that proceeds in the absence of oxygen. The whole process of aerobic respiration takes place in three steps: glycolysis, Krebs’ cycle, and electron transport system.
However, products of anaerobic respiration do not enter into Krebs' cycle (TCA cycle) or the electron transport system (ETS). Here, partial glycolysis results in pyruvic acid. Pyruvic acid undergoes further reduction and gives carbon dioxide and ethanol along with ATP. This is known as alcoholic fermentation.
TCA cycle is another name used for describing the Krebs' cycle since the first component formed in this cycle is a citrate which is a tricarboxylic acid (TCA).
Photorespiration is the type of respiration which is commonly seen in C3 plants. O2 is utilised at the expense of energy and CO2 is released as the by-product. This takes place in C3 plants when the level of CO2 drops significantly. It is minimal in case of C4 plants.
