UNCW BIO 201 2 COMPREHENSIVE
STUDY GUIDE 2026 FULL QUESTIONS
AND SOLUTIONS GRADED A+
◍ selective permeability of membranes.
Answer: small, nonpolar, uncharged molecules can go through membranes
easily
◍ passive diffusion.
Answer: down gradientno energy no transport protein
◍ passive transport.
Answer: down gradientno energy yes transport protein
◍ active transport.
Answer: up gradientyes energy yes transport protein
◍ Cyclin.
Answer: Cellular protein that play an important role in regulating the cell
cycle.
◍ Genome.
Answer: Consists of the complete genetic sequence of a cell.
◍ primary active transport vs secondary active transport.
Answer: primary: the energy source is ATPex. pumpssecondary: the energy
source is concentration gradientex. coupled transporters
◍ Somatic Cells.
Answer: Non-reproductive cells.Have two sets up chromosomes making it a
'diploid' cell.
◍ Gametes.
Answer: Reproducing cells (egg and sperm)Have only a single set of
, chromosomes making it a 'haploid' cell.
◍ hypertonic.
Answer: lots of stuff, little wateranimal: crenationplant: plasmolysis
◍ What are the two main phases of the cell cycle?.
Answer: 1. Interphase 2. Mitotic Phase (Mitosis & cytokinesis)
◍ Mitosis.
Answer: A process of nuclear division in eukaryotic cells that conserves the
number of chromosomes.-produces two daughter cells identical to parent
cells. (n=46)
◍ What are the five stages of Mitosis?.
Answer: 1. Prophase2. Prometaphase3. Metaphase4. Anaphase5. Telophase
◍ hypotonic.
Answer: little stuff, lots of wateranimal: cytolysisplant: turgor
◍ isotonic.
Answer: equal concentration on both sides
◍ Prophase.
Answer: 1st stage of mitosisChromosomes begin to condense and form a
mitotic spindle.
◍ channel.
Answer: discriminates by size and chargeusually ions
◍ Prometaphase and metaphase.
Answer: 2nd and 3rd stage of mitosis -Microtubules (spindle fibers) attach
to the kinetochore (form at centromeres of chromatids) of
chromosomes-Chromosoms align on the metaphase plate
◍ carrier.
Answer: lock and key phenomenonbinds to a certain soluteslower than
channel
◍ exocytosis.
