  1. Glycolysis.

    Hi, I am a molecule of Glucose. I contain six Carbons, twelve Hydrogens, and six Oxygens in that order. I started out as a normal Glucose molecule, but something began to happen…I began to go through a process called Glycolysis. Then I am broken down and I become Pyruvate. During Glycolysis, energy is released and transferred to ATP which is the energy that keeps this cycle continuously repeating. Anyway, I change into Glucose 6-Phosphate. I feel like a whole new molecule.

    Then, I am broken down again but into Fructose 1, 6 Biphosphate, the energy then switches to ADP. Next, I am split in half to Fructose 1, 6 Biphosphate and Phosphoglycer Aldehyde (PGAL). While going through this, I lose a hydrogen from both sides, which makes NAD into NADH. My final stage is Pyruvate, which contains three Carbons, five Hydrogens, and three Oxygens. Out of this cycle there is two ATP made as well as two NADH, and two Pyruvate. This whole reaction occurs in the cytoskeleton of the cell, for the purpose of Pyruvate and energy/ATP.

    The Kreb's Cycle.

    Considering I am now Pyruvate, there is another stage I have to go through: The Kreb's Cycle. As my Carbons and Hydrogens break down, they become Carbon Dioxide. So, as my Hydrogen loses its bond from me, it connects to NAD which becomes NADH, and FAD becomes FADH. This process makes two ATP, six NADH, two FADH, and six Carbon Dioxides. This occurs in the mitochondria.

    The Electron Transport Chain.

    Finally, I arrive at the last step of my journey: The Electron Transport Chain. My Hydrogens' electrons are taken away, and they travel through the transport chain. The Hydrogens bond with the Oxygens, creating water, because Oxygen has its electrons. Out of this last step, thirty two ATP, and six water molecules are made. But, the water is waste. This process is used to get energy.

    Connection.

    Glycolysis, The Kreb's Cycle and the Electron Transport Chain are all connected because Cellular Respiration is this. Therefore, without all three, Cellular Respiration would not be complete.

  2. Work on details. Carbon dioxide does not contain hydrogen. ATP stores the energy that comes from breaking the bonds in glucose.

  3. I'm just a hydrogen atom...I was all alone in this cruel world; I thought I would never find a place where I belong. Until I found some buddies: 6 carbon atoms, 6 oxygen atoms, and 11 other hydrogen atoms just like me! We called ourselves "Glucose". We had bonds that would never be broken...or so I thought.
    One day, me and my homies were all just chillin' in this cool lounge called the Cytoplasm, mindin' our own, when a guy called Enzyme and the ATP brothas came to stir up some trouble. He managed to find two of my Hydrogen friends some twins to get together with, NAD. The remainder of our Glucose group split into 2 groups; each consisting of 3 carbon atoms, 3 oxygen atoms, and 5 total hydrogen atoms. We decided to name our new groups "Pyruvate". After that, the ADP quadruplets took advantage of our broken bonds and used them to make themselves stronger and more energized. They turned into 2 ATP's!
    After our sad departure, my Pyruvate group traveled down to the big city: Mitochondria. There, we saw the other Pyruvate group, going through the same thing we were. Here, we ran into more trouble with Enzymes and ADP. They even had a possy with them consisting of 6NAD and 2FAD. Things got serious when we lost one of our carbon to O2. It's a shame, they were emitted as a waste! 6 total CO2 molecules were lost as a waste in this vicious cycle we were told is named the Krebs Cycle. I thought it was an urban myth! Then, 3 hydrogens from each Pyruvate ( including me) were lost to NAD to make a total of 6NADH, and I saw 2 more hydrogen from each group to bond to a FAD molecule, to make 2FADH2 molecules.
    I had been completely torn apart from my group! I felt so alone and very discouraged. Only 2 ATP were produced at the end of the Krebs Cycle, and it felt very wrong that my whole life was ruined for so little to show for it! My NADH molecule carried me to the downtown of Mitochondria. I was trying to make friends with N, A and D,when I felt a tug on my orbitals. OH MY GOSH MY ELECTRON WAS GONE! She was my one and only electron. Without her, I have a positive charge, but I feel so negative. I HAVE to go find her! I saw her, jumping from protein to protein, and sparks were flying everywhere! I was furious. I went to the end of the chain to wait up for her, but when she got there she bonded with an oxygen molecule! I went to them to give them a piece of my mind, but when I got there, I bonded with the oxygen! Another hydrogen came along and bonded with us, and we became an H2O molecule. Wow! I also saw 32 ATP's that I was told were made by the ATP Synthase. It turns out I had it all wrong. Even though I ended up as part of a waste, I realized that everything happened for a reason. Small reactions happen at different times to make a bigger product in the end. All these ATP's will be used to power the whole cell, which makes only 6H2O and 6CO2 waste molecules sound like a very small price to pay to be able to power the whole cell through cellular respiration.

  4. So there I was just sitting on a cooking enjoying life, when all of the sudden this human picks me up and eats me. I'm inside the human body. Then BOOM!! Some man called ATP hits me and breaks me into 2 parts. I move on down the line and I meet 2 girls named NAD. Then 2 atoms called Hydrogen get chopped off of me and move to NAD. Then I get chopped in half and the energy from this is used to make ATP. So now I am at the second step of cellular respiration. This is called the Krebs cycle. First, I witnessed carbon dioxide (CO2) being released from me. So then that CO2 is now a waste product. So now there is a 6 carbon compound. Then another carbon dioxide is lost from the pyruvate. Now one NADH comes from what is left of the pyruvate and another waste product is made. Now 1 NADH is produced as well as FADH2 and 2 ATP is made as a product. So now I'm at the final stage of cellular respiration. This is called the Electron Transport Chain. 1st the hydrogen from NADH and FADH are taking electrons to the Electron Transport. After this happen 2 electrons flow through the Electron Transport and they end up in an oxygen atom. Then the Hydrogen and the Oxygen atom share the electrons to make water molecules (H2O). Then ATP is produced as a product from the energy from of the Electron Transport Chain and H2O is a waste. Tyran and Ronald

    1. I am assuming you speak from the perspective of glucose. How many of each molecule are produced, and where do each of these reactions occur?

  5. Once there was a little atom called glucose and his friend ATP. ATP was changing to ADP and started being mean and told glucose they wasn’t friends anymore, so he met this boy called phosphate. But phosphate decided to tell ADP to make up with glucose. So he did and all became friends. ADP decides to go to counseling to let out his energy, and it turns out that it helps them realize why they can't be friends. The next day ADP finds a new friend named NAD. They decided to try and let out their energy to make it work and it did. They decided to go out and meet new people together to make more friends. They made friends with 2 more ADP and 2 more NAD, and their parents are hydrogen and glucose and they all came together to create a group called puruvate (C3H5O3). Then next week ADP meet someone named CO2. He found out that his job was to give off waste. As they were going through town they saw puruvate and his girlfriend molecule, they decided to talk to them and they got along, so they decided to be friends. So it made their group bigger. CO2 was getting mad and upset, and ended up breaking up the group, so energy was transferred. So, with their own group, without CO2 they made FADH2, NADH, and ATP. Later that day at the park the gangsters (electrons) was bothering the little kids(hydrogen) and they started to cry and turned into NAD. So the electrons chased them down the slide(electron transport chain).The gangsters mothers(oxygen) came to pick them up to meet their friend hydrogen, to get together and make waste. They went back to the park and played on the slide (electron transport chain) and the gangsters (electrons) are using synthase to make energy to make/find new friends. Then they ended up finding 32ATP.
