,1. Which of the following is a key feature of eukaryotic cells?
A) Ribosomes
B) Nucleoid
C) Nucleus
D) Plasmids
Correct Answer: C) Nucleus
Rationale: Eukaryotic cells are characterized by having a nucleus,
which houses the cell's DNA and is separated from the cytoplasm
by a nuclear membrane.
2. What is the primary function of mitochondria?
A) Protein synthesis
B) Lipid synthesis
C) ATP production
D) DNA replication
Correct Answer: C) ATP production
Rationale: Mitochondria are known as the powerhouses of the
cell because they convert oxygen and nutrients into adenosine
triphosphate (ATP), the energy currency of the cell.
,3. During which phase of cell division do the chromosomes line up
in the center of the cell?
A) Telophase
B) Anaphase
C) Metaphase
D) Prophase
Correct Answer: C) Metaphase
Rationale: During metaphase, chromosomes align at the
metaphase plate (center of the cell) before being separated into
each of the two daughter cells.
4. What is the process by which a gradient of concentration is used
to drive the movement of substances across a membrane?
A) Active transport
B) Osmosis
C) Diffusion
D) Facilitated diffusion
Correct Answer: D) Facilitated diffusion
Rationale: Facilitated diffusion is a process of passive transport,
facilitated by transport proteins, that moves substances down their
concentration gradient without the use of cellular energy.
, 5. Which molecule is the final electron acceptor in the electron
transport chain of aerobic respiration?
A) Oxygen
B) Carbon dioxide
C) ATP
D) Glucose
Correct Answer: A) Oxygen
Rationale: In aerobic respiration, oxygen acts as the final electron
acceptor in the electron transport chain, allowing for the
production of water and the release of energy.
6. What type of bond is formed between two amino acids in a
protein?
A) Glycosidic bond
B) Hydrogen bond
C) Peptide bond
D) Ionic bond
Correct Answer: C) Peptide bond
Rationale: A peptide bond is a covalent chemical bond formed
between two amino acid molecules during protein synthesis.
