Metabolism is C. the total sum of energy of a person's endergonic and exergonic reactions . Therefore , C. the total sum of energy of a person's endergonic and exergonic reactions is correct .
Metabolism refers to the complex set of chemical reactions that occur within a living organism to maintain life.
It involves the processes of breaking down molecules to obtain energy and building up molecules necessary for life processes.
The correct option is:
C. The total sum of energy of a person's endergonic and exergonic reactions.
Metabolism can be broadly categorized into two types of reactions: anabolism and catabolism.
Anabolism involves the synthesis of complex molecules from simpler ones, requiring energy input. On the other hand, catabolism involves the breakdown of complex molecules into simpler ones, releasing energy.
The energy aspect of metabolism is crucial for sustaining life processes. Endergonic reactions absorb energy, while exergonic reactions release energy.
The combination of these two types of reactions determines the overall energy balance in an organism.
In the context of human metabolism, it includes processes such as the digestion of food, the conversion of nutrients into energy, and the synthesis of biomolecules required for growth and maintenance.
Metabolism is regulated by enzymes, which act as catalysts to facilitate and control the speed of biochemical reactions.
Factors such as genetics, age, diet, and physical activity can influence an individual's metabolic rate, impacting how efficiently their body converts and utilizes energy.
Metabolism is essential in various fields, including biology, medicine, and nutrition, as it plays a fundamental role in the overall health and functioning of living organisms.
