Active transport: requires that a cell expend energy to move molecules across a membrane against the solute’s concentration gradient (the side where it is more concentrated) Feedback inhibition: Metabolic reaction is blocked by its products. A product acts as an inhibitor of one of the enzymes in the pathway to regulate metabolism. Centriole: a structure in an animal cell composed of microtubule triplets arranged in a 9+0 pattern. An animal usually has a pair of centrioles within each of its centrosomes

filaments. A Z-disk passes through the center of each I band. The next form of muscle fiber is smooth muscle fiber‚ these fibers are considerably smaller than skeletal muscle fibers. A single smooth muscle fiber is thirty to two hundred micrometers long‚ thick centered and tapered at the ends. These smooth muscle fibers have a single nucleus that is centrally located and oval in shape. Smooth muscle fiber contains thick filaments and thin filaments. These filaments are in ratios of 1:10 and

DissoCubes®‚ I. INTRODUCTION About 10% of the drugs developed by now are poorly soluble and have bioavailability problems. Estimations for the future envisage that about 40% of the newly developed drugs will be poorly soluble and as a result will show problems for attaining a therapeutically significant blood level. Thus‚ there is a crucial demand to find solutions for the fabrication of these poorly soluble drugs. Preferably‚ such a new formulation principle should be relevant to almost any poorly

The Andromeda galaxy‚ 2.5 million light years away. It’s racing through space‚ everything blown apart‚ like shrapnel in an explosion because our universe is expanding with an ever accelerating pace; hence every element of it is going away from its neighbors. We are seeing this galaxy as it was when our ape like ancestors first walked on the African plains. Further through space and further back in time. There is order in this chaos‚ a perfect pattern formation behind the infinite variety‚ an endless

cytoplasmic particles containing enzymes and other substances‚ which originate in the endoplasmic reticulum of vertebrate liver and kidney cells and other cells‚ and in protozoa‚ yeast‚ and many cell types of higher plants. Avarage Size 0.2 - 1.5 micrometers in diameter Function Microbodies contain enzymes that participate in the preparatory or intermediate stages of biochemical reactions within the cell. This is the breakdown of fats‚ alcohols and amino acids. Peroxisome and Glyoxysomes Peroxisome

To put this in perspective‚ one millimeter consists of 1000 micrometers‚ so bacteria are extraordinarily small (“Size and Scale”‚ n.d.) As stated before‚ Bordetella pertussis is a gram-negative bacterium. Gram-negative bacteria have an outer membrane which makes them more resistant to certain antibiotics. Gram-negative

sample mixture through a column filled with a sorbent‚ leading to the separation of the sample components. The active component of the column‚ the sorbent‚ is typically a granular material made of solid particles (e.g.silica‚ polymers‚ etc.)‚ 2–50 micrometers in size. The components of the sample mixture are separated from each other due to their different degrees of interaction with the sorbent particles. The pressurized liquid is typically a mixture of solvents (e.g. water‚ acetonitrile and/or methanol)
