SODIUM/POTASSIUM PUMP • Found in the membrane of all animal cells • Active transport - uses ATP (around 30% of a cell's total ATP usage) breaking it down to ADP and phosphate • Helps maintain membrane voltage (thought to contribute about 10% of total voltage) • Maintains sodium and potassium concentration gradients • Helps maintain cellular volute by regulating a cell's osmolarity • Transports 3 sodium ions out of the cell and 2 potassium ions into the cellThe sodium and potassium ion gradients set up by the pump are required for numerous functions such as: • Nerve cell action potentials • Muscle contractions • Glucose absorption by intestinal cellsSODIUM/POTASSIUM PUMP CYCLE 1) Intracellular sodium ions bind the protein2) Protein becomes phosphorylated (phosphate added)3) Conformational change in the protein due to the phosphorylation ejects the sodium ions to the now accessible extracellular space4) Extracellular potassium binds to the protein5) Protein is dephosphorylated (phosphate is removed)6) Due to dephosphorylation, protein returns to original conformation and ejects the potassium ions intracellularly. The pump is now ready to start the cycle again at step 1.

A diagram of a neuron and its functions.
German biologist and artist Ernst Haeckel dedicated his life studying far flung flora and fauna, drawing each of their peculiar specificities with an immense scientific detail. Haeckel made hundreds of such renderings during his lifetime, works which were used to explain his biological discoveries to a wide audience. In addition to these visual masterpieces, Haeckel also discovered many microbes, and coined several scientific terms commonly known today, such as ecology, phylum, and stem cell. More

Daphnias, also called water fleas, are small planktonic crustaceans. Its body is usually 0.2–6.0 mm long and enclosed in a transparent shell.
Essentially, conjugation refers to the process through which bacteria exchange genetic material. Take a look.
Ernst Haeckel was a turn of the century German biologist that changed the world with his scientific illustrations. Trained in many scientific fields, he not only named multitudes of species, he illustrated them as well. Wikipedia describes him as" an eminent German biologist, naturalist, philosopher, physician, professor and artist who discovered, described and named thousands of new species". Kunstformen der Natur, "Artforms of Nature" is the book of his intricate illustrations. Haeckel's illustrations of invertebrates influence the design world even today. This is a classic Finish 1960's Eero Aarnio mushroom lounge chair. Even basic shapes are mimicked in design. These military insignia are a perfect example of the influence of nature. Haeckel's work, as a design element, is still fresh... These drawings provide endless kaleidoscopic combinations of design. It is easy to see how rosettes and baroque scrollwork are based in the nature that Ernst Haeckel illustrated for us. Haeckel's illustrations can be found in his original book form or through reprinted copies.

Before macro photography showed us tiny things in great detail, Ernst Heinrich Haeckel (16 February 1834 – 9 August 1919) drew life seen through his microscope. The German scientist’s lush drawings, watercolors, and sketches of lifeforms “from the highest mountaintops to the deepest ocean” were published in 59 scientific illustrations between 1860 and 1862. Many of … Continue reading "Gorgeous Prints Of Ernst Haeckel’s Illustrations of Nature"

Prokaryotes are the organisms which have primitive nucleus. All bacteria are prokaryotes because they lack a distinct nucleus with nuclear membrane. The cytoplasm of prokaryotic cells lacks in well defined cell organelles such as endoplasmic reticulum, Golgi apparatus, Mitochondria,centrioles, nucleoli, cytoskeleton. The size of these cells range between 1 micrometre to 3 micrometres, so they are barely visible under the light microscope. Now let's moveon to diagram. 1.Draw a capsule shape which represents a basic structure of Bacilli bacterial cell. Draw two more lines over basic capsule shape which represents Cell wall. Place some dots inside it. 2. Draw one more outer covering with considerable thickness.This represents outer slimy Capsule. Draw some faint oblique lines within to highlight it. 3.Draw several Pili around the Prokaryotic cell as shown, Make a whip like flagellum at the bottom of the cell. Note: A bacterial cell may have more than one flagella but we draw only one for sake of simplicity. 4. Draw Mesosome originating from plasma membrane. 5.Label the parts as shown Cont:- The smallest bacterium is Dialister Pneumosintes (0.15 to 0.3 micrometers) and the largest is Spirillum volutans (13 to 15 micro meters) in length. The outer covering of bacterial cell comprises three layers: Plasma membrane, Cell wall and Capsule. The bacterial plasma membrane also provides a specific site at which the single circular chromosome remains attached. It is the point from where DNA replication starts. Infoldings of plasma membrane give rise to Mesosomes or chondrioids. They form coplex whorls of convoluted membranes, increasing surface area. In Photosynthetic bacteria, these infoldings also form Chromatophores bearing photosynthetic pigments. The bacterial cell wall is rigid chiefly composed of Murein or muramic acid, teichoic acids and teichuronic acids. In some bacteria cell wall is surrounded by an additional slime or gel layer called capsule. It is thick mucilaginous and is secreted by plasma membrane.It serves as protective layer against attack of Phagocytes and by viruses.

Ernst Haeckel, the turn-of-the-century biologist, naturalist, professor, and artist, was an ardent Darwinist, a denouncer of religious doctrine, and a writer of philosophical treatises. He coined terms still in common use today, such as phylum, stem cell, and ecology. He discovered, described, and named thousands of new species, depicting them in sketches and watercolors as notable for their artistic mastery as […]
