Biology final SG1
flashcards for biology final semester 1
| Question | Answer |
|---|---|
| Independent Variable | The variable that is on the x axis |
| Dependant Variable | The variable that is on the y axis |
| Qualitative data | tests quality NO NUMBERS |
| Quanititative data | tests quantity YES NUMBERS |
| Control Group | the group that isn't changed |
| Constants | parts of an experiment that don't change |
| Types of population growth | logistic and exponential |
| Logistic growth | for large animals: reaches a carrying capacity and stops increasing |
| Exponential growth | for small animals: grows by a factor of x |
| carrying capacity | the most animals of one species that an ecosystem can support |
| Primary producers | plants. Make their own food |
| herbivores | secondary consumers. Eat only plants |
| carnivores | terciary consumers. Eat only animals. |
| omnivores | terciary consumers. Eat both plants and animals |
| decomposers | eat dead plants and animals |
| food web | a representation of the different ways animals are connected by food in an ecosystem |
| pyramid of energy | shows all of the trophic levels |
| predatation | hunt for own food |
| parasitism | one creature benefits while the other is harmed |
| mutualism | both creatures are benefited |
| commensalism | neither creature is benefited nor harmed |
| keystone species | a species on which an entire ecosystem depends |
| exotic species | a species that is new to an ecosystem |
| human population | is reaching carrying capacity |
| monosaccharides | single molecule sugars: glucose |
| disaccharides | two molecule sugars: sucrose |
| polysaccharides | many molecule sugars: starch |
| monomer of carbohydrates | monosaccharides |
| monomer of lipids | fatty acids |
| monomer of proteins | amino acids |
| monomer of nucleic acids | nucleotides |
| condesation reaction | makes water |
| hydrolysis | requires water |
| structure of enzymes | 3D; have an active site; are special proteins |
| function of enzymes | lower activation energy for a reaction: catalysts |
| denature | when an enzymes active site is changed and can no longer function |
| coenzymes | required to help enzymes |
| plasma membrane | made up of phospholipids and proteins. Is selectively permeable. |
| phospholipids | have a hydrophilic head and 2 hydrophobic tails |
| cytoplasm | where all reactions in the cell take place |
| ribosomes | make and transport proteins |
| cytoskeleton | keeps the cells shape |
| nucleus | brain of the cell |
| smooth ER | makes fats and breaks down toxins |
| rough ER | associated with ribosomes. Proteins travel through this |
| golgi bodies/apparatus/complex | processes and packages proteins |
| lysosome | digests and recycles waste and dead organelles |
| vesicle | a membrane bound sac that transports large molecules |
| mitochondria | produces energy in form of ATP |
| cell wall | wall of a cell: solid |
| chloroplasts | where photosynthesis takes place |
| vacuole | where water; food; and waste are stored |
| eukaryotic cells | """true nucleus"". Has a nucleus" |
| prokaryotic cells | """before nucleus"". Has no nucleus or many organelles. Circular DNA" |
| facilitated diffusion | happens with channel or carrier proteins. Requires no energy |
| active transport | endocytosis and exocytosis. Requires energy |
| endocytosis | bringing molecules into the cell |
| exocytosis | transports molecules out of the cell |
| ATP | the molecule used for energy by eukaryotic cells |
| Endergonic reactions | use energy |
| Exogonic reactions | release energy |
| Glygolysis | anaerobic: yeilds lactic acid breaks down glucose. GLUCOSE --> ATP+NADH+PYRUVATE |
| fermentation | anaerobic:yeilds ethanol |
| cellular respiration | glycolysis; krebs cycle; electron transport chain |
| Krebs Cycle | PYRUVATE --> NADH=FADH2+ATP |
| Electron Transport Chain | NADH+FADH2 --> ATP |
| Calvin Cycle | ATP --> GLUCOSE |
| Light Dependant Reactions | LIGHT --> ATP |
| Hypertonic | the cell has more of a substance than the solution so it will shrink |
| Hypotonic | the cell has less of a substance than the solution so it will swell |
| Isotonic | the cell has the same amount of a substance than the solution so it will stay the same size |
| chemical formula for cellular respiration | C6H12O6+6O2 --> 6H2O+6CO2+ATP |
| chemical formula for photosynthesis | 6H2O+6CO2+ Light --> C6H12O6+6O2 |
