WHAT ARE GENES
genes are made up of DNA. DNA in turn is made of mulititude of nucleutides. Nucleotide is a chemical compound made up of a nitrogen base, phosphoric acid and sugar.
genes are more known for its function in heredity but it is also respsonsible for the daily activity of the cell : that's why it is called the control center of the cell. Cytoplasmic activity is the due to enzyme-regulated chemical reactions. Genes dictate the kind of structural and globular protein that will be produced. The specialization of cellular function for instance is controlled by the genes.
But genes are inside the nucleus and to command cytoplasmic acitivity it needs to exert its control in the cytoplasm by some mechanism. This is thru RNA synthesis. With specificity of nitrogen base pairing this control mechanism of the genes is almost perfect till the code is translated in the cytoplasm

How Cells Make ATP
by PHOSPHORYLATION... adding a phosphate to ADP ADP + P ------> ATP
a) substrate level phosphorylation...
where a substrate molecule ( X-p ) donates its P to ADP making ATP b) chemiosmosis - [Oxidative Phosphorylation of Krebs cycle & ETC]... food substrates donate e- & protons to acceptor molecules [NADH], i.e., oxidation. NADH gives up electrons & protons are pumped out of mitochondria (or the chloroplasts in photosynthesis); protons diffuse back into mito thru an enzyme - ATPase, the ATPase enzyme makes ADP + P --> ATP figure * c) photophosphorylation.... e- of light energy, instead of food covalent bonds, are captured by chlorophylls to make a proton gradient across the chloroplast membranes... figure* protons move through a chloroplast ATPase enzyme to make ATP
http://student.ccbcmd.edu/biotutorials/energy/chemios.html
Oxidative Metabolism... (cell respiration) occurs in heterotrophic organisms that consume foods ... we say organisms oxidize (consume) foods (often glucose) to make energy because they remove & capture electrons... ... where is energy in foods? it's in the covalent bonds (e-)
Thus - METABOLISM is cells capturing e- via REDOX reactions REDOX REACTION... e- passed from one molecule to another [PGAL --> NAD+] in a chemical rx energy is transferred into the new molecule (a reeox couple) by holding e- OXIDATION = removal of electron &/or proton from food covalent bond REDUCTION = gaining electron &/or proton; adds an electron to an acceptor molecule
Cell RESPIRATION...
a more complete definition of cell respiration : - series of enzyme rx's (biochemical pathways) in the cytoplasm & mitochondria that, - remove e- (oxidation) from covalent bonds of substrates (as glucose), and - pass e- to acceptor molecules [coenzymes] such as NAD+ & FAD* which become reduced [ NADH & FADH2 ] - the reduced coenzymes [ NADH & FADH2 ] pass e- to other acceptors... a series of protein electron carriers called cytochromes, - the electron carriers [cytochromes] pass e- to O2 --reduction--> H2O - cytochromes also pump protons [H+] out of mitochondria into peri-mito space, - protons move back into mito thru a special enzyme (ATPase) & make ATP
KEY Reactions of KREBS CYCLE 1. NAD is reduced (NADH) and FAD is reduced (FADH2) 2. substrate level phosphorylation occurs (GTP <--> ATP) 3. decarboxylation [-COOH] 4.* an acylation reaction via coenzyme-A (forms Acetyl-coA) SUMMARY Reactions: [Krebs Cycle Quicktime Movie*] Summary figure full cycle*

Deep breathing helps alveoli, the small air sacs deep in your lungs, fully expand. When you lie in bed for a long time (while recovering from injuries or surgeries, for instance) you tend to take shallow breaths and not cough as often as needed. You might start taking shallow breaths in an attempt to decrease pain associated with chest surgery or abdominal surgery.
Using an incentive spirometer will help you return to normal breathing rhythms. By inhaling deeply, you also help mobilize secretions and open areas of the lungs that my have collapsed.Using an incentive spirometer will mimic natural sighing and yawning and encourage you to take slow, deep breaths. Not only will this help restore your regular breathing rhythm, but it will also help you avoid atlectasis (a collapsed or airless condition of the lung) and pneumonia.

STUDY THIS PICTURE SHOWING THE DIFFERENT FLUID COMPARTMENTS
Microcirculation is the delivery of fresh blood to the smallest blood vessels, present in the vasculature embedded within organ tissues.Arterioles carry the blood to the capillaries. Blood flows out of the capillaries into the venules. Arterioles contract and relax, varying their diameter and vascular tone, as the vascular smooth muscle responds to diverse stimuli.The term capillary exchange refers to all exchanges at microcirculatory level, most of which occurs in the capillaries. Sites where material exchange occurs between the blood and tissues are the capillaries. Capillary walls allow the free flow of almost every substance in plasma except plasma protein.Diffusion is the first and most important mechanism that allows the flow of small molecules across capillaries. The process depends on the difference of gradients between the interstitium and blood. The Starling equation is an equation that describes the roles of hydrostatic and osmotic forces (the so-called Starling forces) in the movement of fluid acrosscapillary endothelium.

MEMBRANE POTENTIAL --WHAT IS IT? membrane potential is but the negative electrical charge inside the cell brought about by the difference in ionic concentration in and out of the cell. This again is due to the selective permeability of the membrane to these ions

mast cell and non-specific inflammatory response
Mast cells are present in most tissues in the vicinity of blood vessels, and are especially prominent near the boundaries between the outside world and the internal milieu, such as the skin, mucosa of the lungs and digestive tract, as well as in themouth and conjuntiva and nose
Mast cells play a key role in the inflammatory process. When activated, a mast cell rapidly releases its characteristic granules and various hormonal mediators into the interstitium and starts the inflammatory process
