PRATT TEST BANK COMPREHENSIVE TEST
PAPER 2026 COMPLETE ANSWERS
ACCURATE
⫸ Biochemistry. Answer: The study of the chemistry of life at the
molecular level
⫸ Bacterial Cell (4). Answer: - DNA is freely in the cytoplasm (no
membrane - nucleoid)
- Some contain a cell wall
- Some contain flagella
- No organelles
⫸ Animal Cell (3). Answer: - Contains a nucleus (has DNA) that is
surrounded by a membrane
- No cell wall
- Contains membrane bound organelles
⫸ Plasma Membrane (3). Answer: - The periphery of the cell (made up
of lipids & proteins)
- Hydrophobic (repels water), thin, & flexible
, - Hydrophilic things enter through membrane proteins (channels,
receptors, & pumps)
⫸ Embedded Proteins in the Plasma Membrane (3). Answer: -
Transport Proteins: Lets specific things in and out of the cell
- Receptor Proteins: receives signals (hormones, messages, etc)
- Membrane Enzymes: Speeds up reactions in the membrane
⫸ Genome. Answer: The cell's complete DNA
⫸ The 3 Domains of Life. Answer: - Bacteria: lives in soil, water, in/on
organisms
- Archaea: lives in extreme conditions. (ex. high salt conc)
- Eukarya: all eukaryotic organisms
⫸ Aerobic vs. Anaerobic Respiration. Answer: - Aerobic: uses oxygen
- Anaerobic: doesn't use oxygen (Obligate: dies when exposed to O2,
Facultative: can live with or without O2
⫸ Cell Envelope (2). Answer: - The protective layer around prokaryotic
cells
- 3 components: plasma membrane, outer membrane, peptidoglycans
⫸ The 4 Ways Organisms Obtain Energy. Answer: - Phototrophs: Uses
sunlight for energy (plants)
