BSC 2085 Exam 1 Learning Objectives UPDATED ACTUAL Questions and
CORRECT Answers
Plasma Membrane separates the cytoplasm from extracellular fluid and defines the cell boundary
Nucleus contains DNA and RNA and controls cell activities
Mitochondria generates ATP
Rough ER has ribosomes, protein synthesis
Smooth ER no ribosomes, lipid synthesis
Golgi Apparatus Modifies and packages proteins
Lysosomes Breaks down waste in the cell
Peroxisomes Detoxifies harmful substances
Microfilaments Made of actin, for change in shape, for muscle contraction
Intermediate Filaments Strong and durable, keep organelles in place
Microtubules Hollow, move materials, make centrioles and spindle fibers
Microvilli Increase surface area, absorption
Cilia Move fluid across surface
Flagellum Moves the cell (sperm cell)
Integral Proteins embedded in the membrane
Peripheral Proteins attached to the surface
Anchoring Proteins attach cells to other cells or structures
Recognition Proteins identify cells as “self” or “non-self”
Channel Proteins transport substances across the membrane
Carrier Proteins bind specific molecules, change shape to move substances
Receptor Proteins bind ligands (hormones, ions)
Simple Diffusion net movement of particles from high to low concentration
