GAMSAT GAMSAT Biological Sciences and Chemistry 1 — Questions and Answers
Question 1: Which section of the GAMSAT primarily tests knowledge of biological and physical sciences?
- Section I
- Section II
- Section III (Correct answer)
- Section IV
Correct answer: Section III
Section III of the GAMSAT covers reasoning in biological and physical sciences, including chemistry and biology.
Question 2: In the context of GAMSAT biology questions, which process describes the movement of water across a semipermeable membrane from low to high solute concentration?
- Diffusion
- Active transport
- Osmosis (Correct answer)
- Facilitated diffusion
Correct answer: Osmosis
Osmosis is the passive movement of water from an area of low solute concentration to high solute concentration across a semipermeable membrane.
Question 3: Which of the following best describes the role of ATP in cellular biology, a common GAMSAT topic?
- It carries genetic information
- It stores and transfers chemical energy (Correct answer)
- It catalyzes metabolic reactions
- It transports oxygen in the blood
Correct answer: It stores and transfers chemical energy
ATP (adenosine triphosphate) serves as the primary energy currency of the cell, storing and transferring chemical energy for metabolic processes.
Question 4: On a GAMSAT chemistry question, what is the pH of a solution with a hydrogen ion concentration of 1 × 10⁻⁴ mol/L?
- 2
- 4 (Correct answer)
- 6
- 8
Correct answer: 4
pH = -log[H⁺] = -log(1 × 10⁻⁴) = 4.
Question 5: Which type of chemical bond is formed when two atoms share electrons, a concept tested in GAMSAT Section III?
- Ionic bond
- Covalent bond (Correct answer)
- Hydrogen bond
- Van der Waals force
Correct answer: Covalent bond
Covalent bonds are formed when two atoms share one or more pairs of electrons.
Question 6: In GAMSAT biological science, which organelle is responsible for producing proteins via translation?
- Mitochondria
- Nucleus
- Ribosome (Correct answer)
- Golgi apparatus
Correct answer: Ribosome
Ribosomes are the cellular organelles where translation occurs, converting mRNA sequences into proteins.
