Bio Test 1
Question | Answer |
---|---|
Scientific Method | pose a question research hypothesis test your hypothesis analyze results communicate results |
Dependent Variable | dependent |
Independent Variable | doesn't depend on anything |
7 characteristics of Living Things | Living things composed of cells different levels of organization use energy respond to environment grow reproduce adapt |
Hierarchical Organization of Life | Biosphere Ecosystem Community Population Organism Organ system organ Tissue Cell organelle Molecule |
Biological Molecules | Lipids Carbohydrates Nucleic Acids Portions |
# parts of the Cell Theory | basic unit of life all living organisms have cells |
Prokaryote | single stranded DNA OG cell no nucleus no organelles (EXCEPT RIBOSOMES) ALL UNICELLULAR ex bacteria |
Eukaryote | double stranded DNA more complex nucleus has organelles multi or unicellular plants or animals |
Chloroplast | green organelles that make the food FOUND ONLY IN PLANTS |
Chlorophyll | pigment inside chloroplast |
Mitochondria | organelle that releases energy from food POWERHOUSE OF A CELL |
Ribosomes | make protein |
Endoplasmic Reticulum | folded membranes that move proteins around a cell HIGHWAY |
Golgi Bodies | sort and package proteins MAIL |
Vacuoles | stores water,food , waste |
Lysosomes | digest food and breakup the cell when it dies |
Lipids | make up cell membrane |
Nucleic Acids | dna |
Carbohydrates | store energy and sugar |
Protein | made up of amino acids |
6CO2 + H20 + light ----> c6h12o6 + 6o2 | photosynthesis |
602+ c6h12o6 ---> 6co2 + 6h2o + 36 ATP | cellular respiration |
Steps for Cellular Respiration | 1. Glycolysis 2. Krebs Cycle 3. ETC |
How do cells create energy without oxygen ? | 1. Alcoholic Fermentation 2. Lactic Acid |
Alcoholic Fermentation | occurs in bacteria and yeast process occurs in baking and brewing glucose - ethyl alcohol + carbon dioxide = 2 ATP |
Lactic Acid | occurs in muscle cells produce during rapid exercise when the body cannot produce enough oxygen glucose - lactic acid + carbon dioxide = 2 ATP |
