Adenosine triphosphate (ATP) is considered to be the energy currency of life. It is the high-energy molecule that stores the ene
rgy we need to do just about everything we do. ATP can power needed reactions by losing one of its phosphorus groups to form ADP, but you can use food energy in the mitochondria to convert the ADP back to ATP so that the energy is again available to do needed work. Complete the activity to order the general steps of the ATP-ADP cycle in aerobic cellular respiration.
Aerobic cellular respiration occurs in oxygen-rich environments. Respiration in the eukaryotic cell starts off at the cytoplasm; here, glucose is split to produce energy.
thus: C6H12O6 (glucose) + 6 O2 → 6 CO2 + 6 H2O + ≈38 ATP
This occurs via
-Glycolysis
The Kreb's Cycle
-Oxidative Phosphorylation
Further Explanation:
In all eukaryotic cells, mitochondria are small cellular organs bound by membranes, making up most of the chemical energy needed to power the cell's biochemical reactions. This chemical energy is stored inside the produced molecule ATP. Respiration in the mitochondria uses oxygen for the production of ATP in the cycle of the Krebs or Citric acid via pyruvate oxidation (through the cytoplasmic process of glycolysis).
<u>Glycolysis</u>: in the cytoplasm 2 ATP molecules are used in splitting glucose into 2 pyruvate molecules and producing, 4 ATP and 2 electron-carriers in the form of NADH molecules
<u>The Kreb's Cycle:</u> at the mitochondrial matrix- 6 molecules of CO2 are made via combining oxygen and the carbon within pyruvate, it produces 2 ATP oxygen molecules, 8 NADH and 2 FADH2.
<u>Oxidative Phosphorylation:</u> Oxidative phosphorylation defines a mechanism in which NADH and FADH2 made in earlier steps transfer electrons and return to their previous forms in the electron transport chain, NADH+ and FAD. Electrons keep moving down the chain, and the energy they release is used to pump protons out of the mitochondrial matrix. This forms a gradient in which there is a differential in the number of protons on either side of the membrane that the protons flow or re-enter the matrix through the ATP synthase enzyme, making the ATP energy storage molecules from ADP reduction. Once electron transport is finished, three oxygen molecules accept electrons and protons to form water molecules...
So, from my understanding, you put the following steps (Glycolysis, Krebs Cycle (Citric Acid Cycle), Electron Transport Chain, ATP Hydrolysis, and Transition Reaction) in order, so here is the correct order:
Nucleotide triplets (three nucleotides) of DNA and RNA molecules that carry genetic information in living cells. It's the set of rules used by living cells to translate information encoded within geneticmaterial into proteins.
