Question

Respiration involving the use of oxygen to produce energy is called as
A)Plant respiration
B)Anaerobic respiration
C)Animal respiration
D)Aerobic respiration

Answer 1

Hint: Respiration is the flow of oxygen from the outside environment to cells inside the tissues and the movement of carbon dioxide in the reverse way or the physiological mechanism through which the organism obtains energy (ATP and NADPH) by oxidising resources and generating by-products.

Complete answer:
Aerobic Respiration is a mechanism of cell respiration that occurs in the presence of oxygen to derive energy from the food. Such form of airflow is typical in most animals and plants, birds, human beings as well as other mammals. Carbon dioxide and water are emitted as end products in this system. While carbohydrates, protein and fat are being used as reactants, aerobic metabolism is the best route of pyruvate degradation in glycolysis and demands mitochondrial pyruvate to be totally oxidised by the TCA cycle. The outcomes of this cycle are water and carbon dioxide, and also the energy transferred is being used to break the bonds in ADP to make a third group of phosphorus to form ATP, using substrate-level phosphorylation, NADH and FADH2. The capacity of NADH and FADH2 is transferred to even more ATP by way of an electron transport system. Most ATP generated by aerobic cellular respiration is formed by oxidative phosphorylation. 38 ATP molecules can be rendered by oxidised molecules of glucose during aerobic respiration (2 from glycolysis, 2 from the TCA cycle, and about 34 from the electron transport system).

Anaerobic respiration has been used by microbes where neither oxygen nor pyruvate complexes (fermentation) are increased terminal electron receptors. Just an inorganic acceptor like sulphate, nitrate or sulphur is being used. Such species are usually found in uncommon conditions, such as underwater caves or mines at the bottom of the sea. Plants want oxygen to survive, and the mechanism produces carbon dioxide in exchange. Unlike animals and humans, plants don't even have any unique gaseous exchange systems, but they really do have stomata and lenticels (stems) which are actively engaged in gaseous exchange.

Hence, the correct answer is option (D)

Note: Aerobic metabolism is up to 15 times more efficient than anaerobic respiration (that generates 2 ATP molecules per 1 glucose molecule) since the double bond in oxygen is of greater energy than other double bonds or combinations of single bonds in many other popular molecules in the natural world. Aerobic respiration exists in plants and animals all the time. Most aerobic metabolism responses happen within the cells of mitochondria.
