Which organelle is known as the 'powerhouse' of the eukaryotic cell?
Mitochondria
Chloroplast
Nucleus
Ribosomes
The inner membrane of the mitochondria is highly folded. What is the purpose of these folds, called cristae?
Store genetic material
Facilitate protein synthesis
Increase surface area for ATP production
Regulate the passage of molecules
Which cell organelle is known as the 'powerhouse of the cell' because it generates most of the cell's supply of ATP?
Lysosomes
Ribosomes
Mitochondria
Golgi apparatus
Which of the following is NOT a function of cardiolipin?
Stabilizing the structure of respiratory chain complexes
Facilitating mitochondrial cristae formation
Major component of cell membrane fluidity
Apoptosis regulation
Which part of the plant cell is primarily involved in respiration?
Chloroplast
Cell wall
Vacuole
Mitochondria
The primary site of aerobic respiration in eukaryotic cells is the:
Cytoplasm
Nucleus
Ribosomes
Mitochondria
Why is the use of mitochondrial DNA (mtDNA) preferred over nuclear DNA in forensic analysis of highly degraded samples?
Longer sequence length
Greater polymorphism
Higher copy number per cell
Absence of introns
Which of the following statements about the mitochondrial structure is INCORRECT?
The inner mitochondrial membrane is folded into cristae.
The outer mitochondrial membrane is highly folded to increase surface area.
The mitochondrial matrix contains DNA and ribosomes.
The space between the inner and outer membranes is called the intermembrane space.
Mitochondria are known as the powerhouse of the cell. Which of the following features DOES NOT contribute to this function?
Presence of linear DNA
Folded inner membrane (cristae)
Matrix containing enzymes for the Krebs cycle
Presence of its own circular DNA
Which component of the mitochondria is primarily responsible for increasing the surface area for ATP production?
Cristae
Matrix
Outer membrane
Intermembrane space
