where did ATP come from? find out

Photobucket

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*

study this picture showing fluid compartments fo the body

.


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.

principle of diffusion

How molecules distribute itself in microcirculation. Transfer of substances in three compartments: intracellualry and extracellularly( interstitial and intravascularly).

what creates the pressure? It is kinetic motion of of particles that exert the pressure as it collide against each other in a give compartment. Watch and answere some questions

sodium pump - an electrogenic pump

find out how sodium potassium pump restore normal resting electrical gradient of the cell membrane after an action potential. Note the disparity in the number of ions it transport in and out of the cell. The net result is restoring the ionic and electrical gradient in the membrane.
