AP Biology Prep: The Core Four Assessment
The Systems Approach #
Biology is the study of life, but for assessment purposes, it is the study of mechanisms. Don't just identify parts; identify functions.
Strategy: If a question takes longer than 45 seconds, flag it and move on. The Ecology section at the end is often the highest point-per-minute return.
Module 1: The Fundamental Unit #
Think of the cell as a high-security factory. If the machinery fails at one station, the entire organism feels the ripple effect.
Single choice
A cell is failing to properly modify and 'tag' proteins with carbohydrate chains before sending them to the cell surface. Which organelle is likely malfunctioning?
Multiple choices
Which of the following provide evidence for the endosymbiotic theory regarding mitochondria and chloroplasts?
Open question
Compare and contrast simple diffusion with facilitated diffusion. Why does one reach a 'saturation point' while the other does not?
