AP BIOLOGY EXAM STUDY GUIDE AND
TIPS QUESTIONS WITH COMPLETE
ANSWERS
Water diffuses across what? - Answer-the membrane from areas of lesser to greater
solute concentration (osmosis).
Prokaryotic Cells (such as bacteria) lack what? - Answer-a nucleus and contain
ribosomes but no other organelles.
Eukaryotic cells keep their DNA where? - Answer-in a membrane-bound nucleus and
have many types of organelles, including mitochondria, lysosomes, ribosomes, the
Golgi complex, and others.
Mitosis - Answer-is the process in which a cell produces two identical daughter cells. It
stages includes interphase, prophase, metaphase, anaphase, and telephase.
Cytokinesis - Answer-occurs immediately following mitosis and refers to the splitting of
the cell into two new cells.
All cells are surrounded by a? - Answer-plasma membrane
Osmosis - Answer-is the diffusion of water across a semipermeable membrane.
What are the two main types of cells? - Answer-Prokaryotes and Eukaryotes.
The cell starts out in what stage? - Answer-interphase.
Chemiosmosis - Answer-is energy produced by movement of H+ ions across a
membrane against a concentration gradient in both photosynthesis and respiration.
When do coupled reactions occur? - Answer-when the active transport of an ion is
accompanied by a chemical reaction.
Organic Compounds - Answer-are molecules that contain carbon.
Hydrolysis Reaction - Answer-is a compound that dissolves in water and is the
decomposition of something in the presence of water.
Dehydration Reaction - Answer-releases water.
Oxidation-Reduction Reactions - Answer-involve the gain (oxidation) or loss (reduction)
of electrons.
