NEET General 2 — Questions and Answers
Question 1: Which organelle is responsible for the synthesis of ATP through oxidative phosphorylation?
- Mitochondria (Correct answer)
- Ribosome
- Golgi apparatus
- Lysosome
Correct answer: Mitochondria
Mitochondria house the electron transport chain and ATP synthase, producing ATP via oxidative phosphorylation.
Question 2: What is the SI unit of electric charge?
- Ampere
- Volt
- Coulomb (Correct answer)
- Farad
Correct answer: Coulomb
The Coulomb (C) is the SI unit of electric charge, equal to the charge transported by a current of one ampere in one second.
Question 3: Which type of bond is formed between two water molecules?
- Covalent bond
- Ionic bond
- Hydrogen bond (Correct answer)
- Metallic bond
Correct answer: Hydrogen bond
Water molecules form hydrogen bonds between the partially positive hydrogen of one molecule and the partially negative oxygen of another.
Question 4: In Mendel's Law of Segregation, alleles separate during which process?
- Mitosis
- Meiosis (Correct answer)
- Fertilization
- Replication
Correct answer: Meiosis
Alleles segregate during meiosis, specifically during Meiosis I when homologous chromosomes separate.
Question 5: A projectile is launched at 45° to the horizontal. Which quantity is zero at the highest point of its trajectory?
- Speed
- Kinetic energy
- Vertical component of velocity (Correct answer)
- Horizontal component of velocity
Correct answer: Vertical component of velocity
At the highest point, the vertical component of velocity is zero, though the horizontal component remains constant throughout the flight.
Question 6: What is the IUPAC name of the compound CH₃-CH₂-OH?
- Methanol
- Ethanol (Correct answer)
- Propanol
- Butanol
Correct answer: Ethanol
CH₃-CH₂-OH has two carbon atoms with a hydroxyl group, making it ethanol (ethane-1-ol) by IUPAC nomenclature.
Question 7: Which part of the human brain controls balance and coordination of movement?
- Cerebrum
- Medulla oblongata
- Cerebellum (Correct answer)
- Hypothalamus
Correct answer: Cerebellum
The cerebellum coordinates voluntary movements, maintains posture, and regulates balance.
