ATP is broken down giving rise to a fixed amount of energy that can drive the endothermic reactions taking place in which cell organelle of a cell?
Mitochondria
Ribosome
Chloroplast
Lysosome
Mitochondria
Mitochondria are known as the 'powerhouse of the cell' because they are the primary sites of ATP production through aerobic respiration. The energy released from the hydrolysis of ATP is subsequently used by the cell to drive various endothermic (energy-consuming) metabolic processes.
Mitochondria are known as the 'powerhouse of the cell' because they are the primary sites of ATP production through aerobic respiration. The energy released from the hydrolysis of ATP is subsequently used by the cell to drive various endothermic (energy-consuming) metabolic processes.
Mitochondria act like a power plant or a battery charger for the cell, converting raw fuel into portable energy packets (ATP) that can be distributed to run different machines (cellular functions) across the factory.
Mighty Mitochondria: M for Mitochondria, M for Main power source.
ATP+H2тАЛOтЗМADP+PiтАЛ+Energy тАФ The reversible conversion of ATP to ADP representing energy transfer.
During cellular respiration, the oxidation of glucose within mitochondria produces ATP through the Electron Transport Chain and oxidative phosphorylation. The hydrolysis reaction, ATP+H2тАЛOтЖТADP+PiтАЛ+Energy, releases a specific amount of Gibbs free energy (approximately 30.5┬аkJ/mol under standard conditions) to power endergonic reactions within the cell.
Mitochondria possess their own DNA and double-membrane structure.
The process of ATP synthesis in mitochondria is called oxidative phosphorylation.
ATP acts as the universal 'energy currency' of all living cells.
Efficient production of ATP compared to anaerobic pathways.
Production of reactive oxygen species (ROS) as a byproduct.
Muscle contraction
Active transport of molecules across cell membranes
The 'fixed amount' of energy released is generally considered 30.5┬аkJ/mol for the hydrolysis of the terminal phosphate bond under standard biochemical conditions.
Option B (Ribosome) is the site of protein synthesis. Option C (Chloroplast) is the site of photosynthesis. Option D (Lysosome) is the digestive system of the cell.
A is correct тАФ Mitochondria are the organelles responsible for generating most of the cell's supply of ATP.
Remember that while chloroplasts also generate ATP during photosynthesis, they mainly use it internally for the Calvin Cycle; mitochondria are the primary generators for systemic cellular work.
