Question

what are metabolic activities?

Answer 1

Metabolic activity refers to the set of chemical reactions that maintain life in any organism. Metabolic activity involves the transformation of energy and matter in the body, two elements that must always be present for life to be sustained. Two types of metabolic processes are anabolism and catabolism. Anabolism is constructive metabolism, during which small molecules are formed into larger ones, requiring an input of energy. Catabolism is the opposite process; it necessitates an output of energy, and large molecules are broken into smaller ones.

Answer 2

Metabolic activity refers to the set of chemical reactions that maintain life in any organism. The metabolic activity involves the transformation of energy and matter in the body, two elements that must always be present for life to be sustained. Two types of metabolic processes are anabolism and catabolism. Anabolism is constructive metabolism, during which small molecules are formed into larger ones, requiring an input of energy. Catabolism is the opposite process; it necessitates an output of energy, and large molecules are broken into smaller ones.

Human beings are heterotrophs, which means that humans are dependent on organic molecules that have been ingested to meet energy needs. Organic molecules are the building blocks that meet anabolic needs as well. Metabolic activity begins with ingestion when food is taken into the body. Metabolic enzymes come into play during digestion, when food is broken down in the body through a process called hydrolysis. During hydrolysis, starches become sugars, proteins become amino acids, fats become fatty acids and glycerol, and nucleic acids become nucleotides
