Chapter 3: Cell and parts
What is the ‘cell’? Where do ‘cells’ come from?
List the Organelles and their function: CM, mitochondria, ribosome, Endoplasmic Reticulum (R&S), Golgi, Nucleus and nucleolus, cytoplasm, lysosome,
List the membranous organelles vs. the Nonmembranous organelles.
CM – Names? KNOW the Function of the CM? Molecules in CM; structure of CM; Phospholipid bilayer; proteins and Fxs, cholesterol. What is the function of ‘sensitivity’ in the CM and how does this relate to the function of the CM?.
Fluid Mosaic Model of cell membrane and importance, semi-permeable membrane, how molecules in CM support this? Why is it semipermeable? Selectively permeable? What specific molecule gives the CM its flexibility?
Intracellular fluid vs. extracellular fluid vs. blood plasma vs. cerebrospinal fluid vs. all other body fluids. What is ICF and ECF. Know the difference between intra and inter: i.e. intercellular vs intracellular. How is extracellular related to intercellular? Define interstitial?
Define the Transport processes, what kind of molecules/elements use each transport type: Endocytosis vs. exocytosis; diffusion, osmosis, filtration, phagocytosis active transport, pinocytosis, facilitated diffusion, etc. What is a solvent and solute (from chp 2)?
Define iso, hyper, hypo, and tonic, isotonic, Hypertonic, hypotonic, isotonic solutions, and importance; crenation; equilibrium. How are these concepts linked to extracellular and intracellular fluids? Linked to homeostasis?
Define equilibrium. How is it linked to homeostasis?
Define and give examples of each of the 6 classes or Nutrients- what are their characteristics? Define Calorie vs. calorie and kilocalorie; essential nutrient, essential fatty acid, essential amino acid; give examples. What does ‘essential’ mean?
What is cellular respiration? What is glucose? What is its role in cellular respiration?
How is glucose like a flashlight battery? What is the role of O2 and CO2, ADP and ATP in cellular respiration? What is the role of mitochondria and cytoplasm, lactic acid and pyruvic acid in cellular respiration? How do these interact with O2?
KNOW the "basic equation for Cellular Respiration".
Define and describe: Glycolysis, krebs cycle, cytochrome oxidase, aerobic/anaerobic metabolism and where each occurs,
BMR and metabolic roles of Fats, Glucose, and proteins
Why is knowledge of this important? Link drugs we use medicinally to Cellular Respiration.
What is the role of O2 in cellular respiration? What is the role of H?
Be able to link DNA, ribosomes, protein synthesis, endoplasmic reticulum, golgi apparatus, vacuoles, exocytosis; IN ORDER!
Be able to link DNA, Mitosis, centrioles, microtubules,
Protein synthesis – amino acids, nucleotide, Triplet, Gene, Transcription, translation, DNA, RNA Codon/anticodon
t-RNA, mRNA, rRNA, proprotein, proenzyme
Cell life cycle- haploid, diploid, somatic, sex, gamete, DNA, mitosis, meiosis, compare and contrast, IPMAT
DNA- how it’s made, what is the purpose of the product, how it’s an information molecule?
How do the characteristics of water facilitate osmosis, diffusion, active transport, cellular respiration, etc?
Which molecules are involved in each of these? Which specific characteristic(s) of water facilitates this?
How do the characteristics of water help maintain protein functioning? List each characteristic and explain it’s role in maintaining functional proteins.
