The term "anabolic" refers to those biochemical processes in the body which require energy and/or store energy. Anabolic reactions build new and more complex molecules from simpler ones. This is a process which requires energy, but also stores energy in the newly created and larger molecule.Know More
Catabolic processes represent the inverse reaction. They will release energy as larger molecules are broken down into smaller ones. The energy released by catabolic reactions will provide the energy for further anabolic reactions. The energy used to fuel anabolic reactions is stored in ATP, the shorter term for adenosine triphosphate, the coenzyme responsible for the transfer of intercellular energy.
When ATP breaks down into a smaller molecule called ADP, or adenosine diphosphate, it loses one of its three phosphates and releases energy in a catabolic reaction. In the anabolic version, ADP gains a third phosphate and stores energy as it transforms into the larger ATP. This repeating cycle of energy storage and release is referred to as an organism's metabolism, a term which also represents the totality of all the biochemical reactions occurring within an organism. The series of reactions in which one leads into the next are called metabolic pathways.
The anabolic processes help to build up tissues and organs, which also aids in the growth of the organism through increases in muscle mass and the mineralization of bones. Endocrinologists often refer to various hormones as either anabolic or catabolic, depending on which portion of the organism's metabolism they affect.Learn more in Human Anatomy
The iliac furrow, also known as the Adonis belt, refers to the two shallow grooves that run along the hip bones to the pubis. It is rarely used as a defined medical term but is commonly used to discuss the surface anatomy of the abdomen.Full Answer >
Another term for the eardrum is the tympanic membrane, which is the scientific term for the eardrum. The tympanic membrane is a circular layer of tissue that separates the outer ear from the middle ear. It is incredibly thin and only measures roughly 0.1 millimeter thick.Full Answer >
"Duck face" is a term for the facial expression formed when a person puckers their lips in a way that looks like a duck's beak. Duck face, also known as "Myspace face," is also associated with "selfies" posted to social networking sites such as Facebook and Myspace.Full Answer >
Selective permeability is a term used to describe cell membranes. Cell membranes that are selectively permeable only allow certain molecules to cross into and out of the cell. Molecules are able to pass through a selectively permeable membrane through active or passive transport mechanisms.Full Answer >
