Cellular Respiration Glycolysis, Krebs cycle, Electron Transport 3D Animation


how do you turn that bite of food into a chemical that a cell can recognize and use as energy the first step is altering the food into its component chemical compounds and then getting those molecules into yourself that process is called digestion once inside yourself the process of turning that bite of food into useful energy by cellular respiration begins the process of digestion results with carbohydrates and other molecules being removed from the consumed food and transported into the bloodstream from there nutrients like the carbohydrate glucose will leave the bloodstream through a capillary wall and enter a tissue cell once inside the cell cellular respiration will completely oxidize the glucose molecule releasing high-energy electrons the overall goal is to make ATP a storage form of energy for most cells cellular respiration is a four stage process that begins with glycolysis glycolysis literally means splitting sugars and it is the first step of cellular respiration occurring in the cytoplasm of the cell glycolysis consists of two distinct phases and energy investment phase and an energy harvesting phase in the energy investment phase two ATP molecules transfer energy to the glucose molecule forming a six carbon sugar dye phosphate molecule this molecule splits and the energy harvesting phase begins during this phase the two three carbon molecules are converted to pyruvate and ATP is formed glycolysis is a ten step reaction that involves the activity of multiple enzymes and enzyme assistants in the process a net of two molecules of ATP two molecules of pyruvate and two high energy electron carrying molecules of NADH are produced when oxygen is present the pyruvate molecules and NADH enter the mitochondria and the next stage of cellular respiration begins the next stage of cellular respiration involves the movement of pyruvate into the mitochondria where it undergoes oxidation each pyruvate molecule is converted into a compound called acetyl co a in the process of pyruvate oxidation electrons are transferred to nad producing NADH and a carbon is lost forming carbon dioxide the next stage is the citric acid cycle also called the Krebs cycle here acetyl co a will bind with a starting compound called oxaloacetate and through a series of enzymatic redox reactions all carbons hydrogen’s and oxygens in pyruvate ultimately end up as carbon dioxide and water the pathway is called a cycle because oxaloacetate is the starting and ending compound of the pathway for every glucose that enters glycolysis the cycle completes twice once for each molecule of pyruvate that entered the mitochondria during pyruvate oxidation and the citric acid cycle a net of eight NADH to fadh2 to ATP and six co2 are produced for each glucose molecule in order to understand how the majority of the energy is produced by aerobic respiration we need to follow the nadh and fadh2 molecules to the next stage the electron transport chain the electron transport chain is a series of membrane bound carriers in the mitochondria that pass electrons from one to another as the electrons are transferred between the membrane proteins the cell is able to capture energy and use it to produce ATP molecules proteins in the chain pump hydrogen ions across a membrane when the hydrogen ions flow back across the membrane through an ATP synthase complex ATP is synthesized by the enzyme ATP synthase oxygen acts as the terminal electron acceptor by accepting electrons oxygen is reduced to form water a byproduct of the electron transport chain all the high-energy electron carriers from the previous stages of cellular respiration bring their electrons into the chain from this the bulk of ATP from the entirety of cellular respiration is produced a net of 32 to 36 ATP in summary we have seen how the four stages of cellular respiration are responsible for converting the energy found in the glucose molecule into ATP the energy battery of the cell on average thirty six ATP molecules are produced per glucose molecule that enter the cell in the process of producing ATP oxygen is brought in from the bloodstream to be the final electron acceptor in the electron transport chain and the carbon dioxide that is produced as a by-product is released the goal of cellular respiration is to transfer the energy from the food that we eat daily into ATP that our bodies can use this process starts with the eating of a snack or meal and ends with capturing the energy from the complete breakdown of the nutrients into energy and carbon dioxide

    Cellandning:

    C6H12O6 + 6O2 -> 6CO2 + 6H2O + ATP

    Cellen använder Glukos och syre för att tillverka ATP.
    CO2 och vatten som biprodukt.

    Gylkolys:

    En anaerob reaktion händer i cytoplasman, ATP binds till glukos och bildar en 6 kol atom. Molekylen är ostabil o splittras till två 3 kol pyrodruvsyror. Bildar 2 ATP och 2 NADH (koenzym som kan bära elektorner)

    Citronsyracyckel/ Krebs cyckel:

    Acetyl-CoA

    Aerob reaktion i yttre membranen i mitokondrien där Pyrodruvsyran oxideras till Acetyl-CoA. Acetyl CoA binder med en 4 kol molekyl Oxaloacetat. Det sker redox reaktioner och kolen syren och väten bildar CO2 vatten och energi. och det produceras 6 NADH, 2 FADH, 2 ATP och CO2. Acetyl-CoA blir slutprodukten och är startprodukten. För varje glukos går cyckeln 2 gånger.

    Elektrontransportkedja:

    Aerob process i inre membranen av mitokondria. NADH och FADH2 från Glykolys och Citronsyracykeln och deras elektroner fortsätter till inre membranen och tas upp av proteiner, proteinerna pumpar protoner till yttre membranen och används för att bilda en protongradient. Syre från blodet tar till slut emot elektronerna och det bildas h2o. Gradienten balanserad ut till slut av ATP syntas enzymet där ADP kombineras med fosfat och ~34 ATP och H2O bildas.

    Oxidative phosphorylation or electron transport chain,however you wanna call it, it produce 34 molecules of ATP not 32,so as a summary we got 38 ATP molecules,2 from glycolysis,2 from Krebs cycle and 34 from Oxidative phosphorylation.Thats how they teach it in med schools here.

    That's strange, I thought life was assembled at random, with no purpose or goal. Call me crazy, but even the molecules know what to do and when to do it. Each molecule seems to have orders to do certain things with certain other molecules to reach a desired goal. What's that all about?

    La carotte, Daucus carota subsp. sativus, est une plante bisannuelle de la famille des apiacées (aussi appelées ombellifères), largement cultivée pour sa racine pivotante charnue, comestible, de couleur généralement orangée, consommée comme légume. La carotte représente après la pomme de terre le principal légume-racine cultivé dans le monde[2]. C'est une racine riche en carotène. La carotte est un tubercule d'hypocotyle, c'est-à-dire formé pour partie par l'hypocotyle et pour l'autre partie par la région supérieure de la racine, qui se sont tubérisés

    I thought we'd have a yield of 38 ATP molecules by the end of cellular respiration..
    10 NADH
    2 FADH2
    4 ATPs
    Am I counting incorrectly?!
