(products) c6h12o6 + 6o2 ---> 6co2 + 6h2o (reactants)
- Glycolisis occurs in the cytoplasm( cytosol)
- Phosphate group is transferred from ATP to glucose, creating a glucose with 6 phosphates
- The glucose-6-phosphate is turned into a fructose-6-phosphate
- The fructose is then split to form two three-carbon sugars.
- One of the initial three-carbon sugars loses 2 electrons and 2 protons reducing NAD+ to NADH in additon prodcucng an H+
- Then, ADP is given a phosphate which it will use to create a molecule of ATP and creating a 3-phosphate
- One of the 3-phosphates makes 4 ATP where 2 Of them are used and your end product is 2 ATP
- The other 3 - phosphate group in the net converts to glucose giving you an end product of 2 pyruvates plus a molecule of water
Steps of Krebs Cycle
- two carbons pieces of pyruvate is used to make acetyl-CoA
- During the above process carbon dioxide is produced as well as a formed NADH molecule.
- The two-carbon acetyl from the acetyl-CoA is converted into a 4-Carbon molecule, this making a 6-carbon compound
- Carbon dioxide is released from the 6-Carbon making it a 5-Carbon compound. This is where hydrogen is removed and moved to transfer from NADH to NAD+
- Again NADH and Carbon Dioxide are produced. Besides this a molecule of ATP is produced. After this a 4-Carbon molecule is formed.
- The hydrogen that is removed is then used to form NADH and FADH2. This reaction regenerates the 4-Carbon .
- This process has to be done twice to break the pyruvate molecule.
Steps of Electron Transport Chain
- Sunlight hits the chlorophyll and causes the electrons to get excited
- The excited electrons start to travel through the transport chain
- The water molecule then splits to fill the electrons that have moved. This split will produce oxygen and hydrogen molecules.
- The electrons continue their journey, while the electrons are being pumped it gives the protons energy to go from the membrane to the thylakoid space.
- The loose hydrogen move from high to low concentration and into the ATP Synthase.
- The first electrons will now move further down the chain and get hit by the light causing the electrons to get excited again.
- The electrons will then continue through the second transport chain.
- These electrons will be used to create NADPH, and later used in the Calvin cycle .
Importance of Cellular Respiration
Cellular respiration is very important because it provides energy for all living organisms to preform their necessary functions to maintain life.
