Aerobic and Anaerobic Respiration Equation

Respiration releases energy which is stored in glucose and if it stops, the cells will die. There are two types of respiration: Aerobic respiration which occurs in the presence of oxygen and most cells most of the time. On the other hand, Anaerobic respiration occurs without oxygen and much less frequently than aerobic respiration. 

Now the question is how does this process work? To answer the question, we create this fascinating blog. In this, we’ll explore the processes of aerobic and anaerobic respiration equation. Furthermore, if we deeply study the aerobic respiration equation and highlight how our cells produce energy. Whether you’re a student, a teacher, or simply a curious reader, this blog will shed light on every tiny piece of information about this topic. So, buckle up your seat and get ready for an informative journey.

WHAT IS CELLULAR RESPIRATION?

Cellular respiration is a cellular catabolic process which transfers the entire energy in carbohydrate molecules carriers such as adenosine triphosphate (ATP). Moving next, it can take place with and without oxygen. However, aerobic respiration arises when oxygen is present, and it consists of some metabolic pathways: glycolysis, pyruvate oxidation, Krebs cycle, and oxidative phosphorylation.

And, without oxygen, it is known as anaerobic respiration, and it begins with glycolysis but ends when pyruvate is oxidized or decarboxylated. Since ATP, includes the ADP, GDP, and phosphoryl produced in cellular respiration, and then they will be reused in other pathways, the overall cellular respiration equation is 

C6H12O6 + 6O2 –> 6CO2 + 6H2O

Se the equation above, carbohydrates such as starch, glycogen, and sugars, is broken down. As a result, the potential energy embedded in the chemical bonds to cellular energy, which supplies the energy to other anabolic pathways.

TYPES OF CELLULAR RESPIRATION

There are two types of cellular respiration with different equations anaerobic respiration equation and aerobic respiration equation One occurs in the presence of oxygen (aerobic), and one occurs in the absence of oxygen (anaerobic).

AEROBIC RESPIRATION

Aerobic respiration occurs in cells and organisms. It also has four pathways: glycolysis, pyruvate decarboxylation, Krebs cycle, and oxidative phosphorylation 

 

First of all, in glycolysis, glucose molecules are broken down in the cell’s cytosol, generating pyruvate. Molecules of ATP and nicotinamide adenine dinucleotide (NADH) in its reduced form.

Next, the Krebs cycle is a process in the cell that creates energy. During this process, two substances FAD and NAD+ change their places and move from one part of the cell (the mitochondrial matrix) to another (the inner membrane of the mitochondria). After changing their places they also transform their called FADH2 and NADH, and then take part in another process called oxidative phosphorylation. 

This is where they transfer electrons in a series of steps, with oxygen as the final receiver of the electrons. Aerobic respiration is the “full” cell breathing process. This is because all the chemical reactions that happen can be seen as the opposite of what happens during photosynthesis.

Here is the Aerobic Respiration Formula C6H12O6 + 6O2 → 6CO2 + 6H2O

ANAEROBIC RESPIRATION

Anaerobic Respiration Equation refers to fermentation, which happens when cellular oxygen is scarce or absent. It starts with glycolysis when the glucose is converted into pyruvate. Their produced pyruvate molecules are not transported to mitochondria, in contrast to aerobic processes. Rather, they remain within the cytosol and take part in any of the subsequent reactions:

LACTIC ACID FERMENTATION

Pyruvate molecules will undergo glycolysis during lactic acid fermentation and take up the electrons from NADH oxidation. The enzyme known as lactate dehydrogenase helps speed up this reaction where electrons will transfer.

CH3COCOO– + NADH + H+ <–> CH3CH(OH)COO– + NAD+

ETHANOL FERMENTATION

Ethanol fermentation occurs after glycolysis and consists of two steps.

First, the enzyme pyruvate decarboxylase uses vitamin B1 to cleave pyruvate, resulting in acetaldehyde and carbon dioxide. This reaction can be stated as: 

CH3COCOO– + H+ <–> CH3COH + CO2

The first reaction, acetaldehyde will be reduced by NADH oxidation to NAD+. Enzyme alcohol dehydrogenase catalyzes oxidation-reduction reaction in the following reaction:

CH3COH + NADH + H+ <–> CH3CH2OH + NAD+

 

Moreover, ethanol is produced along with the regeneration of NAD+. Just Like lactate fermentation, NAD+ will regenerate to resupply glycolysis, while ethanol is metabolized elsewhere.

WHAT IS THE WORD EQUATION FOR ANAEROBIC RESPIRATION?

Word equation for anaerobic respiration is: Glucose → ethanol + carbon dioxide + energy (2 ATP)

WHAT IS THE WORD EQUATION FOR AEROBIC RESPIRATION?

The word aerobic respiration equation is glucose + oxygen → carbon dioxide + water + energy.

AEROBIC VS ANAEROBIC RESPIRATION EQUATION (KEY DIFFERENCES BETWEEN THEM

Basis for comparison Aerobic respiration Anaerobic respiration
Definition It is a collection of metabolic reactions which take place in the presence of oxygen. taking place in a cell to produce ATPs from chemical energy. On the other hand, Anaerobic respiration is a process of cellular respiration where a high-energy electron acceptor is neither oxygen nor pyruvate derivatives.
Overall equation Aerobic respiration equation 

C6H12O6 + 6O2 →  6CO2 + 6H2O + energy

Anaerobic respiration equation 

C6H12O6  →  C2H5OH + CO2 + energy

Presence of Oxygen It takes place in the presence of oxygen. Anaerobic takes place in a low-oxygen environment.
Exchange of gases There is an exchange of gases during aerobic respiration  The exchange of gases doesn’t take place during anaerobic respiration. 
Location After glycolysis, aerobic respiration takes place in eukaryotic cells’ mitochondria. It occurs only in the cytoplasm of a cell.
Energy produced A total of 38 ATPs produced during aerobic respiration. They produce Only 2 ATPs.
Nature of the process This is comparatively longer than anaerobic. It is shorter than aerobic respiration.
Occurs in They occur in higher organisms like plants and animals. It occurs in primitive prokaryotes. occurs in human muscle cells during vigorous motions as well.

 

EXAMPLES OF AEROBIC RESPIRATION

AEROBIC RESPIRATION IN HUMANS

  • The process of cellular respiration in humans is called aerobic respiration.
  • It begins in the cytoplasm of the cell, and then products move into the mitochondria, where further reactions take place.
  • Next, oxygen will be absorbed by the lungs and stored in the red blood cells. 
  • The glucose is then oxidized and produces energy while releasing carbon dioxide gas.
  • Cellular respiration in humans includes major metabolic pathways for the oxidation of carbohydrates to release energy.

EXAMPLES OF ANAEROBIC RESPIRATION

  • When you do intense exercise, your body cannot get enough oxygen and then they perform more glycolysis than the body can transfer oxygen to the electron transport.
  • The results in anaerobic respiration due to insufficient oxygen in our muscles.
  • This type of anaerobic respiration is known as lactic acid fermentation which produces just 2 ATPs per glucose molecule.

Conclusion 

In conclusion, the processes of aerobic and anaerobic respiration represent fundamental aspects of cellular metabolism, each with its own distinct pathways and implications. Through aerobic respiration, cells efficiently convert glucose and oxygen into energy, sustaining life in organisms ranging from plants to humans. Conversely, anaerobic respiration provides a crucial alternative pathway in low-oxygen environments, albeit with lower energy yields. Understanding these processes not only sheds light on the intricate workings of cells but also underscores the resilience and adaptability of life forms.
