AP Biology practice questions, by topic
Eggzams has 400 original AP Biology questions for the AP exam, organised into 8 topics. Topics include Chemistry of Life, Cell Structure and Function, Cellular Energetics, Cell Communication and Cell Cycle and Heredity. Every question has an explanation after you answer, so a wrong answer becomes a mini-lesson.
Sample AP Biology questions
Here is the kind of question you will get, with the explanation that follows every answer. These are free in the app.
AP Biology · Natural Selection
Homologous structures, such as the forelimbs of humans, whales, and bats, are:
- structures that are reduced and nonfunctional
- structures that evolved independently to perform the same function
- structures found only in fossils
- structures with a similar underlying anatomy inherited from a common ancestor
Homologies reflect shared ancestry even when the functions differ.
AP Biology · Chemistry of Life
A protein loses its function after being heated because:
- its amino acid sequence is rearranged
- its monomers are converted into nucleotides
- its peptide bonds are converted to glycosidic bonds
- its three-dimensional shape is disrupted, although its amino acid sequence stays the same
Denaturation disrupts weak interactions, changing shape and function without breaking peptide bonds.
AP Biology · Cell Structure and Function
Diffusion is the net movement of molecules:
- only through protein pumps
- only across cell walls
- from a region of higher concentration to a region of lower concentration
- from lower to higher concentration using ATP
Diffusion is passive and driven by the concentration gradient.
