- OMG!! Benathen is so handsome when he is dancing!!!!
- Why did he stop??
- I don't know man I am feel extra tired
- Hey man you alright?
- Oh my God, I never thought about that. You might be right!
- DId you not eat? Your cells need food to create ATP you know....
- Whenever you breath and eat, the glucose and the oxygen will set you up for cellular respiration
- And it happens all the time!
- Let's take a closer look at the specific steps!
- The first step of Cellular respiration is Glycolysis! It takes place inside Cytoplasm! The purpose of Glycolysis is to break apart the glucose into pyruvate!
- I am a cell with cytoplasm!
- During the glycolysis, Two phosphate groups are attached to one molecule of glucose, forming a new six-carbon compound. The phosphate groups are supplied by two molecules of ATP, which are converted into two molecules of ADP in the process.
- After that, the six-carbon compound that was formed will split into two three-carbon molecules of G3P!(Glyceraldehyde-3-phosphate
- Then the two G3P molecules are oxidized, with each molecule receiving a phosphate group. It will form a new three-carbon compound! While the G3P are oxidized, two molecules of NAD+ are reduced to NADH.
- And finally, the phosphate groups from the three-carbon compounds are removed! This reaction produces two molecules of pyruvic acid(Pyruvate).
- Each phosphate group is now combined with a molecule of ADP to make a molecule of ATP. And a total of 4 ATP are produced
- Wow it is so complicated.
- Well Glycolysis is very important because glucose is the main fuel for tissues in the body
- At least we are done right?I want to go eat!
- Haha no! There is no stoping in science. We must finish everything about cellular respiration!
- The next step in line is the Krebs cycle, which is the second part of Cellular respiration! The Krebs cycle plays an important role in the process of energy production and biosynthesis. It happens right after Glycolysis, and it fuels the production of ATP! The cycle consumes acetate and water.
- Hello I am mitochondria!
- It takes place in mitochondrial matrix
- At the beginning of the Krebs cycle, A two-carbon molecule of acetyl CoA combines with a four-carbon compound, oxaloacetic acid, to produce a six-carbon compound, citric acid
- Hello I am Citric acid!
- I know citric acid! The lemons have it
- Then the citric acid releases a CO2 molecule and an H atom to form a five-carbon compound. The electron in the hydrogen atom is transferred to NAD+, reducing it to NADH.
- Then, the five-carbon compound that was formed re-leases a CO2 molecule and a hydrogen atom, forming a four-carbon compound. NAD+ is reduced to NADH again during this time!
- Fun fact, a molecule of ATP is also synthesized from ADP.
- Afterward, the four-carbon compound formed releases a hydrogen atom to form yet ANOTHER four-carbon compound. The hydrogen atom is used to reduce FAD to FADH2.
- FAD is a lot like NAD+, they both accepts electrons!
- And finally, the four-carbon compound formed releases a hydrogen atom to regenerate oxaloacetateacid!
- Remember, this keeps the Krebs cycle operating!
- Are we alost done yet! These talks are making me more hungry!!!
- Almost almost, just one more step!
- The last step in cellular respiration is about the electron transportation chain! It is located in the mitochondrial membrane/ The electron transport chain releases the energy that is stored within the reduced hydrogen carriers from previous steps in order to synthesize ATP.
- It's me again!
- This is called oxidative phosphorylation
- Step 1 of the electron transport chain is generating a proton motive force. NADH and FADH2 are oxidized, and they release high energy electrons and protons. These electrons are transferred to here, losing energy while passing through. The energy is used by the chain to pump H+ ions from the matrix, and the accumulation of H+ creates the proton motive force.
- Step 2 of the electron transport chain is ATP synthesis via chemiosmosis. As the proton motive force was created, it will cause H+ ions to move down their electrochemical gradient and diffuse back into the matrix. Such diffusion is called chemosis, and it is facilitated by the transmembrane enzyme ATP synthase. As the H+ ions move through ATP synthase they trigger the molecular rotation of the enzyme, synthesizing ATP
- Lastly, there is the reduction of oxygen. Oxygen acts as the final electron acceptor, and it removes the de-energized electrons to make sure the chain is not blocked. It also binds with free protons in the matrix to form water. Without it, ATP production will be halted.
- Yay we can finally eat something and give my cell something to generate with
- AND WE ARE FINISHED WIH CELLULAR RESPIRATION!
- wait where is my wallet?
- I am not paying for you....
