Question

You are on the second hour of a long weekend morning run. You only ate a small protein bar before your run. Explain what metabolic processes are most active in your body as your cells need to constantly make ATP. In addition, explain what thermoregulatory mechanisms are most likely occurring in your body.

Answer 1

Metabolism is a process of chemical reaction in the cells of living organisms, which converts food into energy. It is the sum of chemicla reaction called catabolic reactions and anabolic reactions to produce energy to the body.

Catbolic reaction: Process of breaking down larger molecules into smaller molecules thus by releasing the energy contained in the chemical bonds. The amount of energy released is not the total amount of energy contained in a molecule. Samll amount of energy yielded by catoolic reaction process are transferred directly as ATP (adenosine triphosphate) molecules. ATP are the energy booster for the cells which can be readily used to support other cells, tissues and organal functions.

Anabolic reaction: The process is quite opposite to that of catabolic reaction, where here all small molecules are joined together to form larger molecule. They combine monosaccharides to form polysaccharides, amino acids to form proteins, fats to form triglycerides and nucleotides to form nucleic acids. For these procees to occur, anabolic reaction needs ATP molecules in the form of energy, which is being generated through catabolic reaction process.

Answer: Catabolic reaction, is the metabolic process which is more active in the body to constantly make ATP.

Thermoregulation: It is a mechanism where, ability of an organism keep their body temperature even when the surrounding temperature is different. Homoestatis ia the state of steady in netrnal, physicalchemical conditions which are maintained in the human body. Human have been able to with-stand varying diversified climates. The core temperatures in humans are regulated and stabilized by hypothalamus, brain linking the endocrine system to the nervous system. Anterior hypothalamic region and the adjacent preoptic regions of the hypothalamus are specifically in responsible for maintaining the core temperature of the body according to the environmental surroundings.
