Cytoplasm notes
half of the motes for the cytoplasm section in the essentials of human A&P
| Question | Answer |
|---|---|
| Explain the Cytoplasm | The cytoplasm is the cellular material inside the plasma membrane and outside the mucleus, most of the cells activities occur here. |
| Function of fermentation | To break down pyruvic acid and regenerate NAD+ for use in glycolysis. |
| 2 forms of fermentation | 1. Lactic acid2. alcoholic |
| Explain inclusions | not functional units, they are chemical substances sometimes present, sometimes not. (i.e. melenin) |
| 3 major element is cytoplasm | 1. Cytosol2. Organelles3. inclusions |
| Explain the mitochondria | kidney beaned shaped, power house of the cell, provides cells ATP |
| Explain organelles | Meta Botic machinery of the cell "little organs" most are bound by a selectively permeable membrane, which allows then to maintian a different internal environment. |
| Explain cytosol | Viscous semitransparent fluid with dissolved protein, sugar and salt. |
| 3 stages of respiration | Glycolosis, Krebs Cycle, Electron transport chain. |
| 3 stages of aerobic respiration | Trasition reaction, Krebs cycle, Electron transport chain. |
| Aerobic respiration equation | C6H12O6+6O2 ----> 6H2O+6CO2+38ATP |
| Explain lactic acid fermentation (and equation) | occurs in animal clls and some unicellular organisms, lactic acid is transported to the liver where it is converted to glucose pyruvic acid + NADH+H ----> lactic acid +NAD |
| Explain alcoholic fermentation (and equation) | Occurs in some plant calles and some unicellular organisms such as yeast. Pyruvic acid +NADH+H+ ----> ethyl alcohol + CO2+NAD+ |
