Which organelle is known as the 'powerhouse of the cell'?
Nucleus
Ribosome
Mitochondria
Golgi apparatus
Mitochondria
Mitochondria are membrane-bound organelles that function as the site of aerobic respiration within eukaryotic cells. They are referred to as the 'powerhouse of the cell' because they generate the majority of the cell's supply of adenosine triphosphate (ATP), which is used as a chemical energy source.
Mitochondria are membrane-bound organelles that function as the site of aerobic respiration within eukaryotic cells. They are referred to as the 'powerhouse of the cell' because they generate the majority of the cell's supply of adenosine triphosphate (ATP), which is used as a chemical energy source.
Just as a power plant burns fuel to generate electricity for a city, the mitochondria 'burn' nutrients to generate ATP to power all cellular functions.
Mitochondria = Mighty Powerhouse.
C6тАЛH12тАЛO6тАЛ+6O2тАЛтЖТ6CO2тАЛ+6H2тАЛO+ATP тАФ The summary equation for cellular respiration.
Mitochondria perform cellular respiration using oxygen to break down glucose into chemical energy. This process involves the Krebs cycle and the electron transport chain located on the inner mitochondrial membrane (cristae), which facilitates oxidative phosphorylation to produce ATP.
Mitochondria possess their own circular DNA and ribosomes, supporting the Endosymbiotic Theory.
They are double-membrane organelles consisting of an outer membrane and an inner membrane folded into cristae.
ATP synthesis occurs primarily via the enzyme ATP synthase.
Efficient energy extraction from glucose via oxidative phosphorylation.
Mitochondrial dysfunction can lead to metabolic diseases and premature cell death (apoptosis).
Skeletal muscle cells have a very high density of mitochondria due to high energy demand.
Essential for processes like cell signaling, cellular differentiation, and calcium storage.
Nucleus: The control center of the cell, containing genetic material (DNA).
Ribosome: The site of protein synthesis within the cell.
Golgi apparatus: The cell's 'post office', responsible for modifying, sorting, and packaging proteins.
C is correct тАФ Mitochondria function as the powerhouse of the cell by generating ATP through the process of aerobic cellular respiration.
Always remember that mitochondria are absent in prokaryotic cells (like bacteria) and mature mammalian red blood cells.
