    Study Notes

    Independent and Dependent Variables

    • Independent variable: The factor that is changed or manipulated by the researcher.
    • Dependent variable: The factor that is measured or observed to see if it's affected by the independent variable.
    • Control group: A group that does not receive the treatment or manipulation to act as a comparison.
    • Null hypothesis: A statement suggesting no relationship between the independent and dependent variables.

    Standard Deviation

    • Standard deviation measures the spread of data around the mean.
    • Low standard deviation: Data points are clustered closely around the mean, indicating high consistency.
    • High standard deviation: Data points are spread out, indicating more variability.

    Standard Error of the Mean

    • Standard error of the mean (SEM) quantifies the variability of a sample mean estimated from a population.
    • High SEM: The means of different samples vary considerably.
    • Low SEM: The means of different samples cluster tightly, indicating high consistency in sampling.
    • Overlapping error bars: Inconsistent data; lack of a meaningful trend.
    • Non-overlapping error bars: Suggests that the observed difference between groups is more significant.

    Data Types

    • Qualitative data: Descriptive data (e.g., colors, textures).
    • Quantitative data: Numerical data (e.g., counts, measurements).
    • Deductive reasoning: General principles to specific conclusions.
    • Inductive reasoning: Specific observations to general conclusions.

    Functional Groups

    • Functional groups: Specific groups of atoms within molecules that dictate their chemical properties. (List functional groups if supplied)

    DNA Structure

    • Deoxyribose and ribose are five-carbon sugars. Structural differences are key for distinguishing these sugars.
    • Complementary base pairs (DNA): Adenine (A) pairs with Thymine (T), Cytosine (C) pairs with Guanine (G).
    • Draw/identify diagrams of monosaccharides, triglycerides, amino acids, and nucleotides according to the provided information.

    Fats

    • Saturated fats: Contain only single bonds between carbon atoms.
    • Unsaturated fats: Contain one or more double bonds between carbon atoms.

    Protein Structure and Function

    • Primary structure: The sequence of amino acids in a protein.
    • Tertiary/Quaternary structure: The overall 3D shape of a protein, resulting from interactions between amino acids and directly affecting protein function.
    • Bonds between DNA base pairs: Hydrogen bonds. (Number of hydrogen bonds between base pairs).

    Carbohydrates, Lipids, Proteins and Nucleic Acids

    • Carbohydrates: Function for energy and structure.
    • Lipids: Store energy, insulate, and form cell membranes.
    • Proteins: Perform various functions, including catalysis, transport, and support.
    • Nucleic acids: Store and transmit genetic information (DNA & RNA).

    Enzyme Factors Affecting Rate

    • List factors influencing the rate of enzymatic reactions (e.g. temperature, pH).
    • Explain how each factor affects enzyme function.

    Types of Chemical Bonds

    • List the types of chemical bonds, as relevant to the context, including ionic, polar covalent, nonpolar covalent, and hydrogen bonds.

    Water Characteristics

    • List 7 characteristics of water.

    Enzyme Inhibitors

    • Competitive inhibitors: Compete with substrate for active site.
    • Noncompetitive inhibitors: Bind to a site other than the active site., altering conformation.

    Cellular Processes

    • Hydrolysis: Decomposition of molecules by reaction with water.
    • Dehydration synthesis: Creation of large molecules by removing water molecules.
    • Photosynthesis: Synthesis of carbohydrates from carbon dioxide. Cellular Respiration: Breakdown of carbohydrates for energy.

    Organelles involved in Protein Synthesis

    • List organelles that play a key role in protein synthesis.

    Compartmentalization

    • Compartmentalization: Separation of cell's activities into different organelles.
    • Importance in cell function: Efficiency and prevention of interference between cellular processes.

    Cell Comparisons

    • Compare characteristics of plant and animal cells including commonalities and dissimilarities
    • Compare characteristics of prokaryotic cells and eukaryotic cells including similarities and differences.

    Cell Organelles and Functions

    • List the functions and description of all the cell organelles and provide examples
