VCE VCE Sciences 2 — Questions and Answers
Question 1: In VCE Biology, which process converts glucose into pyruvate in the cytoplasm?
- Glycolysis (Correct answer)
- Krebs cycle
- Oxidative phosphorylation
- Calvin cycle
Correct answer: Glycolysis
Glycolysis is the first stage of cellular respiration, occurring in the cytoplasm and breaking glucose into two pyruvate molecules.
Question 2: In VCE Chemistry Unit 4, what is 'organic chemistry' primarily concerned with?
- Compounds containing carbon (Correct answer)
- Reactions involving acids and bases
- Properties of metals and alloys
- Electrochemical cells
Correct answer: Compounds containing carbon
Organic chemistry focuses on the structure, properties, and reactions of carbon-containing compounds.
Question 3: In VCE Physics, what is the formula for calculating electrical power?
- P = VI (Correct answer)
- P = V/I
- P = I/V
- P = V + I
Correct answer: P = VI
Electrical power (P) equals voltage (V) multiplied by current (I), expressed as P = VI.
Question 4: Which molecule carries genetic instructions from the nucleus to ribosomes in VCE Biology?
- mRNA (Correct answer)
- DNA
- tRNA
- rRNA
Correct answer: mRNA
Messenger RNA (mRNA) carries the genetic code transcribed from DNA out of the nucleus to ribosomes for translation.
Question 5: In VCE Chemistry, what type of reaction produces water as a by-product when an acid reacts with a base?
- Neutralisation reaction (Correct answer)
- Precipitation reaction
- Combustion reaction
- Redox reaction
Correct answer: Neutralisation reaction
A neutralisation reaction occurs when an acid and a base react to form a salt and water.
Question 6: In VCE Physics, what does 'Hooke's Law' relate?
- The force applied to a spring and its extension (Correct answer)
- The mass of an object and its acceleration
- The voltage across a resistor and current through it
- The wavelength and frequency of a wave
Correct answer: The force applied to a spring and its extension
Hooke's Law states that the force needed to extend or compress a spring is proportional to the distance it is stretched (F = kx).
