AP Biology Exam Review

1. Choose one statement to master. Choose a unit statement…Unit 1 — Water's hydrogen bonding produces cohesion, temperature buffering, and evaporative cooling; the four macromolecule classes differ in monomers, bonding, and function.Unit 2 — Cell size is limited by surface area to volume; membrane transport depends on polarity, proteins, and gradients; internal membranes create specialized compartments.Unit 3 — Enzymes lower activation energy; energy is coupled through ATP; photosynthesis and respiration are driven by membrane proton gradients.Unit 4 — Signals move through reception, transduction, and response; the cell cycle is regulated by internal checkpoints and external signals.Unit 5 — Meiosis and sexual reproduction generate variation; trait transmission follows Mendelian patterns, and phenotype depends on genotype and environment.Unit 6 — DNA sequence is expressed through transcription and translation; regulation controls gene activity, and mutations can change protein function and phenotype.Unit 7 — Populations evolve when heritable variation and differential reproduction act; evidence and models, including Hardy–Weinberg, test evolutionary claims.Unit 8 — Energy flows and matter cycles through ecosystems; populations grow logistically; community diversity is quantified with indices such as Simpson's Diversity Index.
2. Open the AP Biology ChatGPT below and send it this prompt: “Give me a five-question AP-style quiz on the statement I send next. Do not give hints first — grade each of my answers and explain what I missed.” Then paste the statement you chose.
3. Answer all five questions before reading explanations.
4. For every question you got wrong, rewrite the correct idea in the box below in your own words — not the chatbot's sentence.

When you are finished: re-read your saved explanations out loud, then open the chatbot link below and ask one follow-up question on any statement you still cannot explain without notes.
