Body Metabolism Assignment

Question 1: Discuss the mechanisms involved in the metabolism of carbohydrates. 

In this case, metabolism describes the body’s procedure of burning calories and food substances into energy released into the body for body function. Carbohydrate metabolism is done in two primary mechanisms: glycolysis and the Krebs cycle (Scott & Edward, 2018). The glycolysis process of carbohydrates is majorly done in the liver, which is responsible for storing both glucose and glycogen and the distribution of glucose to tissues. More so, the liver is responsible for glycogen breaking down to provide glucose for energy in the body (Sabiston et al., 2022). An intermediate pyruvic acid is necessary for carbohydrate metabolism through bacteria. During glycolysis, pyruvate is produced, which is a three-carbon molecule also formed with glucose, which, when oxidized, further forms acetyl-coenzyme A (Scott & Edward, 2018). Thus, Kreb’s or citric acid cycle removes energy associated with hydrogens and acetyl groups from acetyl-coenzyme A, which are further oxidized for energy production. However, pyruvate is worked upon differently during aerobic and anaerobic respiration.
