Lesson 16 — MDCAT Past Paper Biology Cheat Sheet
In one line: Fifteen mixed-topic facts — biomolecules, physiology, genetics, and plant biology — in classic past-paper style.
Biomolecules & Physiology
1Benedict's test → brick-red for reducing sugars.
2Hydrogen bonds stabilise protein secondary structure.
3Vitamin C deficiency causes scurvy.
4Bohr effect: ↑CO2 → ↓O2 affinity of haemoglobin.
5Insulin lowers blood glucose.
6Nephron is the kidney's filtration unit.
7Enzymes lower activation energy, aren't consumed.
8Competitive inhibition is overcome by excess substrate.
Genetics & Plant Biology
9Meiosis produces 4 non-identical haploid cells.
10Crossing over occurs during Prophase I.
11Stomata regulate gas exchange & water loss in plants.
12Cohesion-tension theory explains transpiration pull.
13Homeostasis = stable internal environment.
14ATP releases energy when its phosphate bond is hydrolysed.
15Phagocytosis = a form of endocytosis.
