Aerobic respiration requires oxygen (O 2) in order to create ATP. Although carbohydrates , fats and proteins are consumed as reactants , aerobic respiration is the preferred method of pyruvate production in glycolysis , and requires pyruvate to the mitochondria in order to be oxidized by the citric acid cycle .
d -Glucose + 2 [NAD] + + 2 [ADP] + 2 [P] i 2 × Pyruvate 2 × + 2 [NADH] + 2 H + + 2 [ATP] + 2 H 2 O Glycolysis pathway overview The use of symbols in this equation makes it appear unbalanced with respect to oxygen atoms, hydrogen atoms, and charges. Atom balance is maintained by the two phosphate (P i) groups: Each exists in the form of a hydrogen phosphate anion, dissociating to contribute ...
For complete oxidation of such compounds, the chemical equation is C x H y O z + (x + y/4 - z/2) O 2 → x CO 2 + (y/2) H 2 O and thus metabolism of this compound gives an RQ of x/(x + y/4 - z/2). For glucose, with the molecular formula, C 6 H 12 O 6, the complete oxidation equation is C 6 H 12 O 6 + 6 O 2 → 6 CO 2 + 6 H 2 O. Thus, the RQ= 6 ...
Phosphorylation is essential to the processes of both anaerobic and aerobic respiration, which involve the production of adenosine triphosphate (ATP), the "high-energy" exchange medium in the cell. During aerobic respiration, ATP is synthesized in the mitochondrion by addition of a third phosphate group to adenosine diphosphate (ADP) in a ...
As calculated by the Henderson–Hasselbalch equation, in order to maintain a normal pH of 7.4 in the blood (whereby the pK a of carbonic acid is 6.1 at physiological temperature), a 20:1 ratio of bicarbonate to carbonic acid must constantly be maintained; this homeostasis is mainly mediated by pH sensors in the medulla oblongata of the brain ...
This is illustrated in the image here, where the balanced equation is: CH 4 + 2 O 2 → CO 2 + 2 H 2 O. Here, one molecule of methane reacts with two molecules of oxygen gas to yield one molecule of carbon dioxide and two molecules of water. This particular chemical equation is an example of complete combustion. Stoichiometry measures these ...

Diagram showing the overall chemical equation. Electrons (e −) are transferred from the cathode to protons to form hydrogen gas. The half reaction, balanced with acid, is: 2 H + + 2e − → H 2. At the positively charged anode, an oxidation reaction occurs, generating oxygen gas and releasing electrons to the anode to complete the circuit:
