CNIH Health Entrance Exam Prep sample questions
Tap any question below to reveal the answer and a plain-English explanation.
Safety Which organelle is responsible for producing ATP through aerobic respiration?
A. Ribosome
B. Golgi apparatus
C. Mitochondria ✓
D. Endoplasmic reticulum
Correct — C. Mitochondria are the primary sites of ATP production through aerobic cellular respiration, using oxygen to convert glucose-derived pyruvate into energy. They contain their own DNA and double membrane system, with the inner membrane housing the electron transport chain and ATP synthase complexes.
Regs What term describes the diffusion of water molecules across a semipermeable membrane from a region of low solute concentration to a region of high solute concentration?
A. Active transport
B. Osmosis ✓
C. Facilitated diffusion
D. Pinocytosis
Correct — B. Osmosis is the passive movement of water molecules across a semipermeable membrane from an area of lower solute concentration (higher water potential) to an area of higher solute concentration (lower water potential). No energy is required because water moves down its own concentration gradient.
Ops Which phase of mitosis is characterized by chromosomes lining up along the cell's equatorial plate?
A. Anaphase
B. Telophase
C. Metaphase ✓
D. Prophase
Correct — C. During metaphase, replicated chromosomes become maximally condensed and align at the metaphase plate — the imaginary plane equidistant between the two spindle poles. This precise alignment ensures each daughter cell will receive one copy of every chromosome when separation occurs in anaphase.
Roles What is the primary function of ribosomes in a cell?
A. Lipid synthesis
B. Protein synthesis ✓
C. DNA replication
D. Energy production
Correct — B. Ribosomes are the molecular machines responsible for translating messenger RNA (mRNA) sequences into polypeptide chains (proteins). They can be free in the cytoplasm or bound to the rough endoplasmic reticulum, and are found in both prokaryotic and eukaryotic cells.
Emergency Which process involves the engulfing of large particles or microorganisms by a cell through membrane extensions?
A. Pinocytosis
B. Exocytosis
C. Phagocytosis ✓
D. Endocytosis
Correct — C. Phagocytosis ('cell eating') is the process by which cells engulf solid particles — including bacteria, dead cells, and debris — by extending pseudopods that surround and internalize the material into a phagosome. This process is central to the immune response, particularly in macrophages and neutrophils.
Safety What is the name of the process by which plants convert light energy into chemical energy stored in glucose?
A. Cellular respiration
B. Photosynthesis ✓
C. Transpiration
D. Fermentation
Correct — B. Photosynthesis takes place primarily in chloroplasts and uses sunlight, water, and carbon dioxide to produce glucose and oxygen. The overall equation is: 6CO2 + 6H2O + light energy → C6H12O6 + 6O2. This process is the foundation of most food chains on Earth.
Regs In which part of the cell does glycolysis take place?
A. Mitochondrial matrix
B. Nucleus
C. Cytoplasm ✓
D. Endoplasmic reticulum
Correct — C. Glycolysis occurs in the cytoplasm (cytosol) of the cell and does not require oxygen. During this process, one molecule of glucose (6 carbons) is broken down into two molecules of pyruvate (3 carbons each), yielding a net gain of 2 ATP and 2 NADH molecules.
Ops Which type of bond holds complementary base pairs together in the DNA double helix?
A. Covalent bonds
B. Ionic bonds
C. Hydrogen bonds ✓
D. Peptide bonds
Correct — C. Hydrogen bonds hold complementary base pairs together in the DNA double helix: adenine pairs with thymine via two hydrogen bonds, and guanine pairs with cytosine via three hydrogen bonds. While individual hydrogen bonds are weak, the millions of them in a DNA molecule provide collective stability while still allowing strand separation during replication and transcription.
