The main function of mitochondria is to produce energy through aerobic respiration. Fatiguing acids and sugars are the main fuels for the generation of ATP. The amount of oxygen available to the cell can affect the number of mitochondria a cell possesses. Mitochondria are divided into two types: aerobic and anaerobic.
Anaerobes are cells that do not use oxygen to generate energy. They are found in the cytoplasm of all cells and are responsible for the production of reactive oxygen species (ROS) that can damage cells. Mitochondrial dysfunction is a major cause of many diseases, including cancer, heart disease, diabetes, and Alzheimer’s disease.

Why mitochondria are present in all aerobic cells?
Higher animals would likely not exist because their cells would only be able to obtain energy from anaerobic respiration, a process that is much less efficient than aerobic metabolism.
In fact, studies have shown that humans can use oxygen in a variety of ways, including as an energy source in the form of ATP (adenosine triphosphate), which can be converted into energy by the Krebs cycle, which is the primary energy-generating mechanism of the body.
In addition, humans are capable of synthesizing glucose from amino acids (the building blocks of proteins), as well as from fatty acids and ketone bodies (bodies of acetoacetate and acetyl-CoA that are produced when glucose is broken down into glucose and pyruvate, respectively).
Where in the mitochondria does aerobic respiration occur?
The answer is that cellular respiration occurs in the mitochondrial matrix through the krebs cycle to form atp, which is then converted to adenosine triphosphate (atp) by the electron transport chain. ETC is a complex consisting of a membrane-spanning ATP synthase complex and an ATP-binding cassette (ABC) complex. ABC complex is responsible for the conversion of ATP to ADP and then back to ATP.
Mitochondria are divided into three sub-units: the cytosolic (cytosol), mitochondrial (mitochondrial) and nuclear (nuclear) subunits. Each subunit has a specific function. For example, the cytoplasmic mitochondrion is involved in energy metabolism, while the nuclear mitochondrial complex plays a role in cell division and cell death. In addition, each subcellular compartment of the cell has its own specific role, such as the respiratory chain and the endoplasmatic reticulum.
What organelle is responsible for aerobic respiration?
Aerobic respiration takes place in the cell’s mitochondria, while anaerobic respiration takes place outside of the cell’s mitochondria. Mitochondria are the energy-generating organelles inside cells. They are responsible for the production of ATP (adenosine triphosphate) and NADH (nicotinamide adenine dinucleotide), which are used by the body to produce energy. Mitochondrial dysfunction can lead to a wide range of health problems, including heart disease, diabetes, cancer, Alzheimer’s, Parkinson’s and other neurodegenerative diseases.
Why mitochondria is called Power House?
Mitochondria are tiny organelles inside cells that are involved in releasing energy from food. The process of cellular respiration is known. Mitochondria are often referred to as the powerhouses of the cell. The mitochondrion is the smallest organelle in a cell and is responsible for the production of ATP, the energy molecule that is used by all cells in the body.
ATP is produced by the action of an enzyme called adenosine triphosphate (ATPase), which is located inside the mitochondrial membrane. ATPase enzyme breaks down ATP into ADP, which can then be used as a fuel source for cells. In addition to producing energy, ATP also plays an important role in regulating the activity of other cellular processes, such as cell division and cell death.
What is the role of mitochondria?
The classic role of mitochondria is oxidative phosphorylation, which generates ATP by utilizing the energy released during the oxidation of the food we eat. Growth, repair, and energy production are some of the processes in which ATP is used as the primary energy source.

Mitochondrial dysfunction is a major cause of many diseases, including diabetes, cardiovascular disease, cancer, Alzheimer’s, Parkinson’s and other neurodegenerative diseases.
How does respiration happen in the mitochondria?
The krebs cycle reactions take place in the matrix of the mitochondria. The electron transport chain and most ATP synthesis are dependent on the inner and outer compartments. The inner mitochondrial membrane is made up of three layers: the mitochondrial matrix, the cytoplasmic membrane, and a membrane-associated protein complex (MAPC).
The inner mitochondrion is surrounded by a complex of membrane proteins called the mitotic spindle complex. (mtDNA) is located in the cytosol and is transcribed into messenger RNA (mRNA) and ribonucleic acid (RNA). mtDNA results in a loss of mitochondrial function.
Mutations in mitochondrial DNA can lead to a variety of diseases, including cystic fibrosis, sickle cell anemia, muscular dystrophy, Huntington’s disease, multiple sclerosis, amyotrophic lateral sclerosis (ALS), and other neurodegenerative diseases.
What stages of aerobic cellular respiration occur in the mitochondria?
The four stages of cellular respiration are: Glycolysis, which does not require oxygen and occurs in the mitochondria of all cells, the three stages of aerobic respiration, all of which occur in the mitochondria, and the bridge (or transition) reaction. The transition reaction is the process by which the energy from food is converted into ATP (adenosine triphosphate), which is then used to power the cell.
This reaction occurs at a rate of about 1.5 ATP molecules per second, or about one ATP molecule per kilogram of body weight per minute. It is important to note, however, that this rate is dependent on the amount of food that is consumed. For example, if a person consumes only one gram of protein per day, then the rate at which this reaction takes place will be much lower than if the same person consumed two grams of carbohydrate.
What does the cell use during aerobic respiration?
During aerobic cellular respiration, glucose reacts with oxygen, forming ATP that can be used by the cell. Carbon dioxide and water are created as waste. The overall equation for aerobic cellular respiration is: In cellular respiration, glucose and oxygen react with each other to form ATP, which is then used to power the body’s energy production.
CO 2 is released into the air, it is absorbed by plants and animals, causing them to respire. These reactions are called endocytosis and endosymbiosis, respectively, because they involve the transfer of energy from one part of a cell to another.
Why does anaerobic respiration not occur in mitochondria?
In aerobic metabolism, 4-5% of the energy is generated by glycolysis. In the presence of oxygen, the rate of energy production is increased by the oxidation of pyruvate to lactate, which is then converted to ATP. This process is called oxidative phosphorylation, and it is the most important energy-producing process in the body.
It is also responsible for the production of glucose and fatty acids, as well as the synthesis of proteins, lipids and nucleic acids. In addition, it plays an important role in cell growth, differentiation and apoptosis.
