Heart cells have a high demand for energy to sustain constant contraction. As a result, they have a larger number of mitochondria compared to other cell types. Mitochondria are responsible for generating the majority of cellular energy through aerobic respiration, producing the ATP needed for muscle contraction. The abundance of mitochondria in heart cells allows for efficient energy production and helps meet the energy requirements of the heart muscle.
Mitochondria are like a hydraulic dam because both store and produce energy. Mitochondria convert nutrients into energy molecules called ATP, which is essential for cell function. Similarly, a hydraulic dam converts the potential energy of water into kinetic energy, which is used to generate electricity.
Adenosine triphosphate (ATP) is the energy carrier molecule used by mitochondria. It stores and releases energy within cells, making it an essential molecule for various cellular processes. mitochondria produce ATP through cellular respiration, where energy from nutrients is converted into ATP.
Mitochondria are thought to be descendants of ancient free-living bacteria that were engulfed by a host cell through endosymbiosis. Over time, the host and the endosymbiont developed a symbiotic relationship, with the host providing protection and nutrients while the endosymbiont provided energy in the form of ATP through aerobic respiration. This symbiosis eventually led to the evolution of eukaryotic cells, including our own.
The mitochondria can be compared to the power plant of a company. Just like the mitochondria, which produce energy for the cell, the power plant generates energy for the company's operations. Both are critical for the overall functioning and productivity of the system.
After pyruvate is brought into the mitochondria, it undergoes a series of enzymatic reactions called pyruvate decarboxylation. In this process, pyruvate is converted into acetyl-CoA, which can then enter the citric acid cycle (also known as the Krebs cycle or TCA cycle) to produce energy in the form of ATP.
One structure found in both plant and animal cells besides mitochondria is the nucleus. The nucleus is the central organelle that contains the cell's DNA and is responsible for regulating gene expression and controlling cell activities.
Muscle cells require a high amount of energy to contract and generate force. Mitochondria are the powerhouses of the cell, responsible for producing energy in the form of ATP through oxidative phosphorylation. Therefore, muscle cells have a large number of mitochondria to meet their high energy demands and sustain prolonged periods of muscle activity.
Mitochondria in nerve cells play a critical role in energy production. They generate adenosine triphosphate (ATP), which serves as the main energy currency for the cell. This ATP is essential for various cellular processes, including nerve impulse transmission, synaptic transmission, and overall neuronal function. Mitochondria are also involved in calcium regulation and the maintenance of cellular homeostasis in nerve cells.
Mitochondria are responsible for producing the majority of a cell's energy in the form of adenosine triphosphate (ATP) through the process of cellular respiration. Around 90% of a cell's energy needs are typically met by the mitochondria, making them crucial for the overall functioning of the cell.
Mitochondria get rid of carbon dioxide and water as chemical waste products. Carbon dioxide is produced during the process of cellular respiration, while water is a byproduct of the electron transport chain in mitochondria.
The fluid found in the innermost part of mitochondria is called the mitochondrial matrix.
The mitochondrial matrix is a viscous fluid that contains the mitochondria's DNA and ribosomes. It is vital to the production of ATP: The mitochondrial matrix is part of the proton gradient that runs the oxidative phosphorylation part of ATP production, and the citric acid cycle (another step in the production of ATP) occurs in this matrix.

The matrix is the innermost space within a mitochondria
It can be compared to a power house.It generates enery in cell.
Reduction/Oxidation reaction
Biologically it is a catabolic reaction,breaking of molecules. It also a exogonic reaction
Mitochondria have matrix in middle.It is also called the cristae.
They are eukaryotic organells.Chloroplast conducts photosynthesis.Respiration take place in mitochondria.
She suggested that michondria and chloroplasts are descendents of prokaryotic endosymbionts.
no virus is a protenious structure but not use mitrochondria is bio chemical cycles are totally different
It will not get energy. Functions of cells would be stopped
