Exam 1 for NU560
Eukaryotes - ANS-Cells that contain nuclei, larger, larger intracellular anatomy, have organelles

Prokaryotes - ANS-no organelles, no encasing of genetic material

- ANS-structure and support

Cellular Fx: Movement - ANS-

Cellular Fx: Conductivity - ANS-

Cellular Fx: Metabolic Absorption - ANS-take in an use nutrients

Cellular Fx: Secretion - ANS-

Cellular Fx: Excretion - ANS-

Cellular Fx: Respiration - ANS-cell can use oxygen and convert it energy

Cellular Fx: Reproduction - ANS-cells divide to form new cells

Cellular Fx: Communication - ANS-communicate, ex: neurotransmitters

3 Components of a cell - ANS-plasma membrane, intracellular organelles, cytoplasm

Nucleus - ANS-Control center of the cell, prominent organelle, 10% of space, it contains the
genetic material, surrounded by nuclear envelope,

Cytoplasm - ANS-fills the space between the nuclear envelope and the plasma membrane

Cytoplasm function - ANS--synthesis and transport
-isolates and eliminates wastes
-metabolic processes
-maintenance of cellular motility
-storage

Ribosomes structure - ANS-Ribonucleic acid (RNA protein complexes: free vs. attached
ribosomes

Antibiotics (some work) - ANS-by shutting down the ribosomes in bacteria

, Ribosomes fuction - ANS-synthesize proteins

Endoplasmic reticulum structure - ANS-network of tubular or saclike channels: smooth vs rough
endoplasmic reticulum

Endoplasmic reticulum fuction - ANS-process, transports molecules to their specific destinations
either inside or outside the cell, site of protein synthesis; senses cellular stress

Ribosomes are nucleoproteins that - ANS-synthesize a signal recognition sequence

Golgi Complex structure - ANS-flattened, smooth membranes, secretory vesicles and cisternae,
proteins from the ER that are package in the golgi complex

Golgi complex fuctions - ANS-refining plant and directs traffic, processes, secretes and releases
substances especially protein from cells

Golgi complex functions - ANS-finishing, packaging, and mailing center, sends them to their final
destination

Lysosomes - ANS-recycling center(recycle worn out cell parts) and garbage trucks

Lysosomes structure - ANS-saclike structures that originate from the Golgi complex

Lysosomes fxn - ANS-intracellular digestion system, role in auto-digestion and autophagy,
digest foreign bacteria that invade the cell and rid the cell of toxic substances

Peroxisomes structure - ANS-contain oxidative enzymes, are the major sites of oxygen
utilization

Peroxisomes functions - ANS-detoxify compounds and fatty acids, use oxygen to remove
hydrogen atoms from substrates, synthesize specialized phospholipids for nerve cell
myelination

Mitochondria structures - ANS-is surrounded by a double membrane, have their own genetic
material that separates from the DNA in the nucleus,

Mitochondria fxn - ANS-convert food to energy your body can use, is responsible for cellular
respiration and energy production, participates in oxidative phosphorylation, ATP is made in the
mitochondria, make copies of themselves

Cytosol structure - ANS-1. Semiliquid highly organized gelatinous mass
2. 55% of cell volume
