RESPIRATION

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Aerobic and Anaerobic respiration are exothermic reactions what does this mean
A
They transfer energy to the environment
B
They take in energy from the environment
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -Exothermic processes generate heat, which raises the heat from the surrounding environment. Examples include ice melting, evaporation, and cooking. Because heat is produced during the process of respiration, it is an exothermic process. The carbon dioxide in the food breaks down to create glucose during the process.

Detailed explanation-2: -Respiration is a burning process of food in body to produce energy. Respiration is considered as an exothermic reaction because, in respiration process, oxidation of glucose takes place which produces a large amount of heat energy which stored in the form of ATP.

Detailed explanation-3: -In aerobic respiration, the end products obtained are carbon dioxide and water. This is due to the complete oxidation of glucose. However, in anaerobic respiration, the incomplete or partial oxidation of glucose takes place which results in the release of ethanol and carbon dioxide.

Detailed explanation-4: -Aerobic: Aerobic respiration takes place in the mitochondria and requires oxygen and glucose, and produces carbon dioxide, water, and energy. (glucose + oxygen-> carbon dioxide + water). Anaerobic respiration also produces energy and uses glucose, but it produces less energy and does not require oxygen.

Detailed explanation-5: -In exothermic reactions, more energy is released when the bonds are formed in the products than is used to break the bonds in the reactants. Exothermic reactions are accompanied by an increase in temperature of the reaction mixture. Chemical reactions that absorb (or use) energy overall are called endothermic.
