Which organelle is known as the “powerhouse of the cell”?
Answer: Mitochondria
Explanation: Mitochondria generate energy in the form of ATP (Adenosine Triphosphate) through cellular respiration.
Which type of energy is produced by mitochondria?
Answer: ATP
Explanation: ATP (Adenosine Triphosphate) is the primary energy currency of the cell, synthesized by mitochondria.
Which organelle has its own DNA apart from the nucleus?
Answer: Mitochondria
Explanation: Mitochondria have their own circular DNA, allowing them to replicate and produce some of their own proteins independently.
Which process takes place inside mitochondria to release energy?
Answer: Cellular respiration
Explanation: Mitochondria break down glucose and oxygen through cellular respiration to release energy in the form of ATP.
Which gas is required by mitochondria for energy production?
Answer: Oxygen
Explanation: Oxygen is essential for aerobic respiration in mitochondria, helping to generate ATP.
Which type of cells have the highest number of mitochondria?
Answer: Muscle cells
Explanation: Muscle cells require a large amount of energy for contraction and movement, so they contain many mitochondria.
Which part of mitochondria contains enzymes for ATP synthesis?
Answer: Inner membrane
Explanation: The inner membrane of mitochondria has folds called cristae, which contain enzymes required for ATP production.
Which scientist discovered mitochondria?
Answer: Richard Altmann
Explanation: Mitochondria were first observed by Richard Altmann in the late 19th century and later named by Carl Benda.
Which organelle is responsible for heat production in brown fat cells?
Answer: Mitochondria
Explanation: Mitochondria in brown fat cells generate heat instead of ATP to help maintain body temperature.
Which type of respiration occurs in mitochondria?
Answer: Aerobic respiration
Explanation: Aerobic respiration occurs in mitochondria, using oxygen to break down glucose and produce ATP
