THE START OF GLYCOLYSIS!!!
Glycolysis starts with Hexokinase which is the conversion of D-Glucose into Glucose 6 Phosphate (G6P). Next is step 2, Phosphoglucose Isomerase, which is rearrangement of G6P into Fructose 6 Phosphate (F6P). From there we go to step 3, Phosphofrutokinase, with magnesium as a co-factor, changes F6P into fructose 1, 6 Bi-Phosphate. Step 4 is Alsolase, which splits fructose 1, 6 Bi-Phosphate into 2 sugars that are isomers of eachother (DHAP), (GAP). Last is, Triphosphate Isomerase, which rapidly inter-converts molecules DHAP and GAP is removed and energy is eventually made. Glycolysis happens in the Cytoplasm of every living organism. 1 major input of Glycolysis is glucose and then the outputs are 2 pyruvate and if oxygen is available then there becomes ATP and NADH energy.
Some major steps of the krebs cycle are starting off with condensation, combining 2 carbon acetyl groups with 4 carbon, making 6 carbon molecule of citrate. Next cirtate loses 1 water molecule and gains another as it is converted into isomer. Then isocitrate is oxidized which produces a 5 carbon molecule with a molecule of CO2 and 2 electrons, which reduce NAD+ to NADH. Next we have step 4 which is very similar to step 3, just with some ATP and a few other elements. After 4 is step 5 which consits of a phosphate group that is subsituted for coenzyme A, and a high energy bond is formed. Step 6 is the dehydration process that converts succinate into fumarate. 2 hydrogen atoms are transferred to FAD, producing FADH2. Last is step 7, which is when water is added to fumarate and then make Malate, making another molecule of NADH. The Krebs Cycle takes place in mitochondrion. The inputs of the krebs cycle are 2 pyruvates, 2 Acetyl CoA and the outputs are 2 ATP 8 NADH 6 CO2 AND 2 FADH2.
Electronic transport chain
34 ATP come from 1 molecule of Glucose in this branch of Cellular Respiration. ETC takes place in the membranes of the mitochondria in eukaryotic cells.
OVERALL IMPORTANCE OF CELLULAR RESPIRATION:
LOCAL: Cellular respiration is important because it provides energy for all living organisms so that we can get on with our everyday lives and be able to do what we need to do.
GLOBAL: Cellular Respiration is important around the globe as well because people would be lazy without energy, then the world would take a turn for the worst and unemloyment would skyrocket.
