| Term | Definition |
|---|
| Cell Cycle | DNA synthesis + cell reproduction |
| Unicelled eukaryotes produced | New organisms |
| Multicelled eukaryotes used the cell cycle for | Maintenance and repair of cell + growth |
| Prokaryotes produce new bacteria by | Binary Fission |
| Binary Fission is simpler than the | Cell Cycle |
| The Five Stages of the Cell Cycle | Interphase, Prophase, Metaphase, Anaphase, Telophase |
| The Four stages of Interphase | G1, S, G2, M |
| G1 | Active Growth Period; Protein Synthesis; No Dividing; Nerve Cells and RBC stay here |
| S | DNA Synthesis of new set of genes; Errors = mutations (SOME harmful) |
| G2 | Short growth with small amount of protein and RNA synthesis |
| M | Mitosis stage with chromosome replication & production of 2 nuclei from 1 & cell division |
| Prophase | Chromosomes condense, nuclear envelope disappears, microtubules form spindle fibers which attach to centromeres of chromosomes |
| Metaphase | Chromosomes line up in middle of cell |
| Anaphase | Centromere divides and the 2 chromatids become separate chromosomes which move to opposite ends of the cell |
| Telophase | 2 new nuclear envelopes form round the 2 groups of chromosomes at poles and the cell splits |
| At the end of mitosis, the cell begins | G1 again |
| Electrons can either be | shared or transferred |
| The higher the magnification of a microscope, the | Smaller the field of view is |
| The lower the magnification of a microscope, the | Larger the field of view is |
| What two things get passed down through reproduction | Genes and mutations |
| Hydrogen bonds are | Weak |
| Ionic bonds are | Stronger than hydrogen bonds, but weaker than covalent bonds |
| Covalent bonds are | Strong |
| Peptide bonds connect | Amino Acids |
| A theory is a | prediction |
| Respiration and photosynthesis are related because | Respiration used the products of Photosynthesis as reactants & vice versa |
| Genetic Engineering | Manipulating DNA in cells to improve health |
| Examples of Genetic Engineering | HGH, Insulin |
| During genetic engineering, the gene is inserted into the | Bacterial plasmid |
| For an object to look normal under a microscope, it must be placed | Upside down and backwards |
| Lamarck’s theory was based on | Acquired traits being inherited |
| Darwin’s theory was based on | Organisms changing over time, leading to variations |
| When dealing with a bioethical situation, three things you should are | Weigh factors, respect human life, and don’t play games |
| Scientific Method | Problem, Hypothesis, Experiment (Materials + Procedure), Results, Conclusion |
| The control is the | Standard for comparison |
| The number of protons in a molecule = | Electrons and Atomic # |
| The number of neutrons = | Mass # - Atomic # |
| Atom | Smallest particle of element |
| Isotopes are different from regular molecule in that | They have different numbers of neutrons |
| Organic compounds contain | C and H |
| Carbohydrates are made up of | Monosaccharides |
| Lipids are made up of | Fatty acids and glycerol |
| Proteins are made up of | Amino Acids |
| Nucleic Acids contain | DNA and RNA |
| ATP and NADP are | Energy storing compounds |
| Enzymes catalyze | Specific substrates |
| DNA contains | Deoxyribose Sugar |
| DNA Phosphates | A+T, G+C |
| RNA contains | Ribose Sugar |
| RNA Phosphates | A+U, G+C |
| Photosynthesis Reactants | 6CO2 + 6H20 |
| Photosynthesis Products | C6H12O6 + 6O2 |
| Photosynthesis Equation | 6CO2 + 6H2O -> C6H12O6 + 6O2 |
| Respiration Reactants | C6H12O6 + 6O2 |
| Respiration Products | 6CO2 + 6H2O |
| Respiration Equation | C6H12O6 + 6O2 -> 6CO2 + 6H2O + 38ATP |
| Autotrophs are either photosynthetic or | Chemosynthetic |
| Leaf Stomates open in | Light |
| Leaf Stomates swell with | Water |
| The three steps of cellular, aerobic respiration | Glycolysis, Krebs, ETC |
| The whole point of Respiration is to make | 38 ATP |
| Fermentation takes place when there is a lack of | Oxygen |
| Two Types of fermentation | Lactic acid and Alcoholic |
| How many ATP does fermentation make | 2 |
| Ecosystem | Producer-Consumer-Decomposer |
| Heat doesn’t recycle because of | Loss of heat |
| The age of our universe is | 15Billion |
| The age of Earth is | 4,6 Billion |
| The age of the earliest fossils | 3.5 Billion |
| Decomposition | Breaking down reaction |
| Urinary System | Urea concentration is high in urine since kidneys keep the level of urea low in blood |
| Light Reactions | Chlorophyll in thylakoids absorb light, convert it to ATP; Splits H2O into H2 + O, and NADP carries the H2 to the Calvin cycle |
| Dark Reactions | (Calvin Cycle) CO2 gets fixated into 2 molecules of PGA, then to PGAL with the NADPH + ATP form light |
| The cell membrane is made of | Two Phospholipid layers |
| Phospholipids are made of | Proteins |
| Wilting is also known as | Plasmolysis |
| Low osmotic pressure | low solute = hypotonic |
| High osmotic pressure | high solute = hypertonic |
| Isotonic | equal amt. of solute on both sides |
| Hypotonic | too much water and can lyse |
| Hypertonic | too little water and can shrivel (crenation) |
| Passive transport | no energy needed |
| Watson and Crick discovered | The structure of DNA double helix |
| Franklin and Wilkins discovered | DNA is the same language in all organisms |
| Schwann & Schleiden developed the | Cell Theory |
| Schwann discovered | Animal Cells |
| Schleiden discovered | Plant Cells |
| Vircow believed in | Biogenesis |
| Biogenesis | Living cells can come only from other living cells |
