Anabolism (/ ə ˈ n æ b ə l ɪ z ə m /) is the set of metabolic pathways that construct macromolecules like DNA or RNA from smaller units. [1] [2] These reactions require energy, known also as an endergonic process. [3] Anabolism is the building-up aspect of metabolism, whereas catabolism is the breaking-down aspect. Anabolism is ...

Anabolism collectively refers to all the processes of chemical reactions that build larger molecules out of smaller molecules or atoms; these processes are also known as anabolic processes or anabolic pathways. The opposite of anabolism is catabolism, the set of processes that breaks down larger molecules into smaller ones. Anabolism and catabolism...
Anabolic pathways in a cell lead to the formation of larger, more complex molecules from smaller ones. First, catabolic pathways are needed to break down nutrient molecules from food into small building blocks. These smaller molecules are then joined together to make different, bigger molecules called macromolecules. Anabolic pathways involve the i...
Protein Synthesis
Proteins are macromolecules that carry out cellular activities encoded by an organism’s genes. They have many different functions in the body, including DNA replication, aiding chemical reactions (as enzymes), transporting materials in the cell, cell growth and signaling, and providing physical structure. Each cell in the human body contains about 1 to 3 billion proteins. Proteins are synthesized from smaller molecules called amino acids in a cell’s ribosomes. Each protein is a chain of a spe...
DNA Synthesis
Deoxyribonucleic acid, or DNA, is an organism’s genetic material. It is macromolecule made up of smaller molecules called nucleic acids, which are themselves made up of a nucleotide base attached to a deoxyribose sugar and a phosphate molecule. DNA synthesis is an anabolic process that takes place in a cell’s nucleus just before the cell divides. It involves unzipping the double strands of DNA and attaching new matching nucleotides to each half of the strand that has been unzipped, forming tw...
Growth of Bones and Muscles
On a larger scale, the growth of body parts such as bones and muscles is anabolic. Bone growth, or ossification, occurs when bone is formed from cells called osteoclasts. It is then mineralized through cells called osteoblasts. This process is also anabolic; during mineralization, osteoblasts produce calcium phosphate crystals that are incorporated into the bone’s structure, making the bones hard and sturdy. Muscle growth, also called muscle hypertrophy, occurs when the cells of skeletal musc...
Anabolic steroids are androgenic hormones that are natural (e.g. testosterone) or produced synthetically and mimic the effects of testosterone. Androgens are anabolic; they increase protein within muscle cells, which causes an increase in muscle mass. Anabolic steroids are used to treat certain medical conditions like delayed puberty in boys, and t...
Catabolism– The set of processes that breaks down large molecules into smaller ones.Metabolic pathway– A series of chemical reactions in the cell.Macromolecule– A very large and complex molecule.Anabolic steroids– Hormones used to treat conditions in which an increase in muscle mass is needed; they are also sometimes abused by athletes.1. Which is NOT an example of an anabolic process? A. Bones grow and mineralize. B. Nutrients from food are broken down for use in chemical reactions. C. Anabolic steroids increase muscle mass. D.DNA is synthesized from nucleic acids. 2. Which effect of anabolic steroid abuse can only occur in males? A. Masculinization B. Feminization C. High blood...

Jul 13, 2021 · What is anabolism? Anabolism is the opposite of catabolism: It’s the mechanism that takes smaller units like nutrients, cells, or amino acids and bonds them together to create bigger structures.
Anabolism, the sequences of enzyme-catalyzed reactions by which relatively complex molecules are formed in living cells from nutrients with relatively simple structures. Anabolic processes, which include the synthesis of such cell components as carbohydrates, proteins, and lipids, require energy in.
