In a biological system, which organelle acts as the 'powerhouse' by generating Adenosine Triphosphate (ATP)?
Lysosome
Ribosome
Mitochondria
Golgi Apparatus
Mitochondria
Mitochondria are known as the 'powerhouses of the cell' because they generate most of the cell's supply of adenosine triphosphate (ATP), which is used as a source of chemical energy. They are double-membraned organelles found in most eukaryotic cells.
Mitochondria are known as the 'powerhouses of the cell' because they generate most of the cell's supply of adenosine triphosphate (ATP), which is used as a source of chemical energy. They are double-membraned organelles found in most eukaryotic cells.
Mitochondria act like a power plant or generator inside a factory, converting raw fuel (glucose) into usable electricity (ATP) to power all cellular machinery.
Mitochondria is Mighty (Mighty Mitochondria makes ATP)
C6тАЛH12тАЛO6тАЛ+6O2тАЛтЖТ6CO2тАЛ+6H2тАЛO+ATP тАФ Overall cellular respiration reaction
Cellular respiration occurs inside mitochondria, specifically through the Krebs cycle and oxidative phosphorylation in the inner mitochondrial membrane. The electron transport chain creates a proton gradient that drives ATP synthase to produce ATP from ADP and inorganic phosphate.
Mitochondria have their own circular DNA (mtDNA) and ribosomes.
The inner membrane folds into structures called cristae to increase surface area for ATP production.
High efficiency in energy (ATP) production via aerobic respiration.
Produces reactive oxygen species as byproducts during oxidative phosphorylation.
Energy production in muscle contraction, neural signaling, and active transport across membranes.
Option A (Lysosome) contains digestive enzymes for intracellular waste breakdown.
Option B (Ribosome) is responsible for protein synthesis.
Option D (Golgi Apparatus) modifies, sorts, and packages proteins for secretion.
C is correct тАФ Mitochondria generate ATP through cellular respiration, earning them the title of the cell's powerhouse.
Remember that mitochondrial DNA is inherited exclusively maternally, which is a frequently tested concept in competitive biology exams.
