18 Questions
The inner membrane of mitochondria forms folds known as cristae.
True
Cristae are involved in ATP production within mitochondria.
True
The mitochondrial matrix is a fluid containing enzymes, proteins, ribosomes, ions, and DNA.
True
Enzymes in the mitochondrial matrix are not essential for ATP synthesis.
False
The primary role of mitochondria is to regulate cell metabolism.
False
Mitochondria are not involved in apoptosis (programmed cell death).
False
During the G1 phase of the centrosome cycle, the duplication of centrosome occurs.
True
In the mitotic phase of the centrosome cycle, chromosome disorientation takes place.
False
Centrosomes help in maintaining the chromosome number during cell division.
True
Centrosomes stimulate changes in the shape of the cell membrane by osmosis.
False
The cytoskeleton is responsible for facilitating the intracellular transport of molecules within the cell.
True
The eukaryotic cell cytoskeleton is composed of a network of fibrous structures and motor proteins.
True
The centrosome contains two perpendicular centrioles: a father centriole and a son centriole.
False
Centrosomes play a role in cell division initiation before the S-phase.
True
During interphase, centrosomes organize mitotic spindles.
False
Centrosomes are not critical for the structural organization of the cell.
False
Proteins synthesized in the cytoplasm are used within the endoplasmic reticulum.
False
Centrosomes are involved in nucleation and anchoring of cytoplasmic microfilaments.
False
Test your knowledge about the centrosome cycle phases and functions. Learn about the duplication, maturation, separation, and chromosome disorientation phases. Explore how centrosomes aid in cell division and maintenance of chromosome number.
