Metabolism and energyOne way of categorizing metabolic processes, whether at the cellularanabolic metabolism examples or organism level, is as "anabolic" metabolksm as " catabolic ", which is the opposite and thus the separation of a macromolecule. Anabolism is powered by anabolic metabolism examples, where large molecules are dxamples down into smaller parts and then used up in cellular respiration. Many anabolic processes are powered by the hydrolysis of adenosine triphosphate ATP. Anabolic processes tend toward "building up" organs and tissues. These processes produce growth and differentiation of anabolic metabolism examples and increase in body size, a process that involves synthesis anabolic metabolism examples complex molecules. Examples of anabolic processes include the growth and anabolic metabolism examples of bone and hgh natural in muscle mass.

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 are the two types of metabolic pathways. Metabolic pathways are series of chemical reactions that take place in the cell. Anabolic pathways use energy, while catabolic pathways release energy. 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 input of energy, which is needed to form chemical bonds between smaller molecules to make macromolecules.
Molecules built from anabolism are then used to build structures in the cell, or even to help build new cells. Anabolic hormones are chemicals that cause cellular growth through activating anabolic pathways. Two examples of anabolic hormones are testosterone and insulin. Hormones can also be produced artificially in the lab; this is how anabolic steroids are created. 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. Each protein is a chain of a specific sequence of amino acids. Since proteins are larger molecules put together from smaller ones, the process of protein synthesis is anabolic.
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. It involves unzipping the double strands of DNA and attaching new matching nucleotides to each half of the strand that has been unzipped, forming two new strands that each contain half of the old DNA strand.
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. Muscle growth, also called muscle hypertrophy, occurs when the cells of skeletal muscles, called myocytes, increase in size. It occurs through strength training exercises such as lifting weights. Factors like sex, age, and diet all affect hypertrophy. During hypertrophy, there is increased protein synthesis of actin and myosin, and the volume of sarcoplasmic fluid in the myocyte increases.
Anabolic steroids are androgenic hormones that are natural e. 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 they can also be used for muscle growth, to stimulate the appetite, to produce secondary sex characteristics in transgender males, and to help treat certain conditions that may cause a loss in muscle mass, such as cancer and AIDS.
However, sometimes anabolic steroids are also abused by athletes who want to quickly gain more muscle. Most major sports organizations ban doping, the use of anabolic steroids or other performance-enhancing drugs, in order to discourage steroid abuse.
Although using steroids can increase muscle mass, it also has many adverse side effects. Steroids can affect the structure of the heart, which could lead to congestive heart failure or a heart attack. They also have adverse effects on cholesterol levels, may stunt height, and can lead to liver damage in high doses. In females, steroids can cause masculinization, which is the development of male secondary sex characteristics such as a deeper voice, increases in body hair, an enlarged clitoris the clitoris in females is homologous to the penis in males , and temporary disruption of the menstrual cycle.
In males, however, steroids can cause feminization, including the development of breast tissue and decrease in testicle size.
This occurs because testosterone can be converted to estradiol, a female sex hormone. These bottles obtained from a drug raid contain anabolic steroid capsules. Which is NOT an example of an anabolic process?
Bones grow and mineralize. Nutrients from food are broken down for use in chemical reactions. Anabolic steroids increase muscle mass. DNA is synthesized from nucleic acids. Answer to Question 1 B is correct.
Anabolic processes involve making larger molecules from smaller ones. Choices A, C, and D are all anabolic processes. Choice B is a catabolic process; it describes larger molecules being broken down into smaller ones. Which effect of anabolic steroid abuse can only occur in males? High blood pressure D. Liver damage Answer to Question 2 B is correct. Since testosterone can be converted to the female sex hormone estradiol, males who abuse steroids may develop breast tissue and their testicles may decrease.
These effects are collectively called feminization. Although steroid use is sometimes used to treat delayed puberty in boys, choice A is incorrect because this question is referring specifically to steroid abuse; masculinization in this context is the development of male sex characteristics in females who abuse steroids. Neither use nor release Answer to Question 3 A is correct. Energy is needed for anabolism to occur because chemical bonds are formed when larger molecules are created. During catabolism, the opposite of anabolism, chemical bonds are broken and energy is released.
