Which organelle is known as the 'powerhouse' of the eukaryotic cell?
Lysosome
Mitochondria
Ribosome
Golgi apparatus
Mitochondria
Mitochondria are known as the 'powerhouse' of the eukaryotic cell because they generate most of the chemical energy needed to power the cell's biochemical reactions. This energy is stored in a small molecule called adenosine triphosphate (ATP).
Mitochondria are known as the 'powerhouse' of the eukaryotic cell because they generate most of the chemical energy needed to power the cell's biochemical reactions. This energy is stored in a small molecule called adenosine triphosphate (ATP).
Think of mitochondria as the internal power plant or generator of a city, burning fuel to supply electricity (ATP) to every building and household in the cell.
Mighty Mitochondria Make Money (ATP)
C6тАЛH12тАЛO6тАЛ+6O2тАЛтЖТ6CO2тАЛ+6H2тАЛO+ATP тАФ Cellular Respiration Equation
Cellular respiration occurs inside the mitochondria through the Krebs cycle and oxidative phosphorylation. Energy derived from nutrients like glucose is converted into ATP via the electron transport chain located on the inner mitochondrial membrane.
Mitochondria possess their own circular DNA (mtDNA) and ribosomes.
They have a double-membrane structure with folds called cristae that increase surface area for energy production.
High efficiency in ATP production through aerobic respiration
Generates reactive oxygen species (free radicals) as byproducts
Energy supply in high-demand cells such as muscle and nerve cells
Tracing maternal lineage using mitochondrial DNA
Option A (Lysosome) is known as the suicidal bag of the cell containing digestive enzymes.
Option C (Ribosome) is responsible for protein synthesis.
Option D (Golgi apparatus) is involved in modifying, sorting, and packaging proteins.
B is correct тАФ Mitochondria are called the powerhouse of the cell because they produce ATP via cellular respiration.
Always remember that red blood cells are the only human cells that lack mitochondria, relying entirely on glycolysis for energy.
