What is the function of mitochondria in a cell as tested in ESAT Biology?
Answer: Site of aerobic respiration and ATP production
Mitochondria are the sites of aerobic respiration, producing the majority of a cell's ATP.
Which molecule carries genetic information in most organisms?
Answer: DNA
Deoxyribonucleic acid (DNA) stores genetic information in the sequence of its nucleotide bases.
What is the process by which plants make glucose using light energy?
Answer: Photosynthesis
Photosynthesis converts light energy, CO₂, and water into glucose and oxygen in chloroplasts.
What does the ESAT Biology section typically assess?
Answer: Cell biology, genetics, and physiology
The ESAT Biology component covers cell biology, genetics, physiology, ecology, and evolution.
What is the role of enzymes in biological reactions?
Answer: They act as biological catalysts, lowering activation energy
Enzymes are biological catalysts that speed up reactions by lowering the activation energy without being consumed.
In Mendelian genetics, if both parents are Aa, what proportion of offspring will be homozygous recessive (aa)?
Answer: 1/4
A Punnett square for Aa × Aa gives AA:Aa:aa = 1:2:1, so 1/4 are homozygous recessive.
