"Prokaryotic" Meaning
A term used in biology to describe an organism or cell that lacks a nucleus and other membrane-bound organelles. Prokaryotic cells are typically smaller and simpler in structure than eukaryotic cells, and are found in bacteria and archaea.
"Prokaryotic" Examples
Examples of Prokaryotic Cells:
1. Bacteria: Most bacteria, such as E. coli and Lactobacillus, are prokaryotic cells with a single circular chromosome and an absence of membrane-bound organelles.
2. Archaea: This domain includes methanogens, like Methanobrevibacter, which are prokaryotes with wall-less cells and membrane-bound organelles that facilitate various physiological processes.
3. Cyanobacteria: A group of prokaryotic organisms that are capable of photosynthesis, converting light energy into chemical energy, and are known for their role in producing oxygen in the early Earth's atmosphere.
4. Anammox Bacteria: These prokaryotic organisms are capable of anaerobic ammonium oxidation (anammox), a process environmentally important for the nitrogen cycle in various ecosystems.
5. Thermophiles: Some species of thermophilic prokaryotes, such as Thermus aquaticus, can thrive at extremely high temperatures above 70°C, contributing to several important biotechnological discoveries.
Understanding prokaryotic cells offers insights into bacterial physiology, genetics, and their diverse roles in ecosystems, from disease and decomposition to nutrient cycling and the creation of our atmosphere.

Prokaryocyte
A prokaryocyte, also known as a prokaryote or protoctist, is an organism that lacks a true cell nucleus. This is in contrast to eukaryocytes, also known as eukaryotes, which have a defined nucleus and other membrane-bound organelles.<br><br>Prokaryocytes are typically found in the Kingdom Monera, which includes bacteria and other single-celled organisms that are thought to have evolved before eukaryotes. Prokaryocytes have a single circular chromosome, lack membrane-bound organelles, and reproduce by a process called binary fission.
Prokaryota
Prokaryotae
Prokaryotae (also known as Eubacteria) refers to a grouping of prokaryotic cells that have a cell wall made of peptidoglycan (murein) and relatively primitive cellular structures. They typically lack membrane-bound organelles, such as a true nucleus, mitochondria, and chloroplasts. Prokaryotes are often single-celled and include bacteria and archaea.
Prokaryote
A prokaryote is a simple type of living cell that lacks a nucleus and other membrane-bound organelles. Prokaryotes are usually unicellular and have a single DNA molecule that is found in a region of the cell called the nucleoid. They are the simplest form of life and can be found in a variety of environments, including soil, water, and within other organisms.<br><br>Examples of prokaryotes include bacteria, such as Escherichia coli (E. coli), and archaea, such as Thermococcus kodakarensis. Prokaryotes are capable of a wide range of metabolic processes, including photosynthesis, chemosynthesis, and decomposition, and play a crucial role in many ecosystems. They are also able to reproduce quickly and efficiently, often by undergoing binary fission, a process in which a single cell divides into two identical copies.
Prokaryotes
A type of microorganism that lacks a cell nucleus and other membrane-bound organelles, such as mitochondria. These cells have a single circular chromosome and lack a true nucleus, and their DNA is not separated from the rest of the cell by a membrane. Examples of prokaryotes include bacteria and archaea.
Proke
Proke is a rare word in English and it has two possible meanings.<br><br>1. A proke is a cant term in some English trucking companies for a truck, especially a hgv vehicle.<br>2. In Church of England, proke and episkope (also spelled episcopy) can refer to a deacon who is licensed to serve local churches or a group of churches.
Prokinetic
Prokinetics
Prokinetics refers to the stimulation of gastrointestinal motility, or the movement of food, fluids, and gas, through the digestive tract. This can involve various medications, natural substances, or physical exercises that help speed up the digestive process, improve digestion, and reduce symptoms of impaired gut motility, such as bloating, nausea, or constipation.

Prolactin
Prolactin is a hormone produced by the pituitary gland that plays a crucial role in breast development and milk production in women and offspring survival in mammals, including humans. It is often referred to as the "lactation hormone." <br><br>In females, prolactin:<br><br>1. Prepares the breast tissue for milk production during pregnancy: <br>2. Initiates milk production during lactation <br>3. Maintains milk production during lactation <br>4. Aids in the secretion of milk from the mammary glands<br><br>In both males and females, prolactin is involved in a range of physiological processes, including:<br><br>1. Regulating immune responses and inflammation<br>2. Controlling appetite and metabolism<br>3. Regulating sleep-wake cycles<br>4. Aiding in the body's response to stress<br><br>An imbalance of prolactin can lead to various issues, including:<br><br>1. Prolactinomas: benign tumors of the pituitary gland that cause an overproduction of prolactin, leading to excessive milk production (galactorrhea)<br>2. Hypopituitarism: decreased production of prolactin and other hormones, often due to pituitary gland damage.<br>3. Increased risks for autoimmune disorders, like rheumatoid arthritis and thyroid disorders<br><br>A healthcare professional, particularly an endocrinologist, can help manage prolactin-related issues and provide guidance on prolactin tests and the best treatment options.
Prolactinaemia
Prolactinaemia is a medical condition characterized by an elevated level of prolactin in the blood. Prolactin is a hormone produced by the pituitary gland in the brain that stimulates milk production in women during pregnancy and lactation. High levels of prolactin can be caused by various factors, such as pregnancy, childbirth, polyps or tumors in the pituitary gland (prolactinomas), hypothyroidism, trauma, or medication side effects including antipsychotic medications, certain antidepressants, and antiemetics for example metoclopramide.
Prolactinemia
Prolactinoma
Prolactinoma is a type of non-cancerous (benign) tumor that occurs in the pituitary gland, a small gland located at the base of the brain. Prolactinoma occurs when a non-cancerous tumor forms on one of the lobes of the pituitary gland and causes an overproduction of prolactin, a hormone that stimulates milk production in the breasts.<br><br>This excess production of prolactin can lead to various symptoms, including:<br><br> Intermenstrual bleeding (unpredictable menstrual periods)<br> Delayed puberty in adolescents<br> Erectile dysfunction and decreased libido in men<br> False or patchy baldness in women<br><br>Treatment for prolactinoma typically involves medication to reduce prolactin levels, and in some cases, surgery may be necessary to remove the tumor.
