Which is called the Powerhouse of the cell?), Mitochondria, What are the folds of the inner membrane of mitochondria called?, Cristae, Mitochondria have their own ____, DNA, How many membranes does mitochondria have?, Two membranes., Name the two membranes of mitochondria., Outer membrane and inner membrane., What is cristae?, Cristae are folds of the inner mitochondrial membrane that increase surface area., What is matrix?, Matrix is the fluid-filled space inside mitochondria containing enzymes and DNA., Why are cristae important?, Cristae increase the surface area for ATP synthesis., What is ATP?, ATP stands for Adenosine Triphosphate. It is known as the energy currency of the cell., What is the main function of mitochondria?, The main function is to perform cellular respiration and produce energy (ATP), Why are mitochondria called strange organelles?, They are called strange organelles because they have their own DNA and ribosomes, which allows them to synthesize some of their own proteins., What is the significance of cristae?, The inner membrane is deeply folded to form cristae. These folds increase the surface area for chemical reactions that generate ATP., Draw a neat labeled diagram of Mitochondria and explain its structure., ✭Outer Membrane: This is a smooth, continuous phospholipid bilayer that surrounds the organelle. It contains integral proteins called porins, which allow the passage of small molecules and ions.✮Inner Membrane: This membrane is highly folded into finger-like projections called cristae. These folds significantly increase the surface area available for chemical reactions, specifically the Electron Transport Chain.✮Intermembrane Space: This is the narrow region between the inner and outer membranes. It plays a crucial role in oxidative phosphorylation by maintaining a proton gradient.✮Matrix: The innermost compartment of the mitochondrion. It contains a complex mixture of enzymes, ribosomes, and mitochondrial DNA. This is where the Krebs cycle (Citric Acid Cycle) takes place.✮Mitochondrial DNA (mtDNA): Unlike most organelles, mitochondria have their own circular DNA and can replicate independently within the cell., Why do muscle cells have more mitochondria?, Because muscle cells require more energy for movement., Write the funtions of Mitochondria., ✭Energy Production (ATP Synthesis): The primary function is to perform cellular respiration. It converts nutrients (glucose) into ATP (Adenosine Triphosphate), the energy currency of the cell.✮Regulation of Metabolism: They help in various metabolic pathways, including the Krebs Cycle, which is essential for processing the food we eat.✮Calcium Storage: Mitochondria act as a storage tank for calcium ions (Ca2+), which are vital for cell signaling and muscle contraction.✭Apoptosis (Cell Death): They decide which cells need to be cleared away. They trigger programmed cell death to ensure damaged cells do not multiply.✭Heat Production: In certain tissues (like brown fat), mitochondria generate heat to maintain body temperature, a process known as non-shivering thermogenesis.
