Study Notes

Multiple Choice Questions

Life Characteristics: Ability to grow, develop, reproduce, and maintain homeostasis are characteristics of life.
Independent Variable: In an experiment studying light's effect on plant growth, the amount of light exposure is the independent variable.
Mutualism Example: Bees pollinating flowers is an example of mutualism.
Higher Level of Organization: The biosphere includes all other levels of organization (organism, population, ecosystem).
Ionic vs. Covalent Bonds: Ionic bonds transfer electrons, while covalent bonds share electrons.
Water Property: Water has a high heat capacity.
Ribosome Production: The nucleolus is responsible for making ribosomes.
Hypertonic Solution Effect: In a hypertonic solution, water leaves the cell causing it to shrink.
Mitochondrial Process: The Krebs cycle occurs in the mitochondria.
Energy Transfer in Food Chain: Typically, 10% of the energy is transferred from one trophic level to the next in a food chain.
Amino Acid Central Atom: Carbon is the central atom in an amino acid's structure.
Microscope Focus: The coarse adjustment knob is used to adjust focus at low power.
Chloroplast Process: Photosynthesis occurs in the chloroplasts.
Enzyme Role: Enzymes decrease the activation energy needed for biochemical reactions.

Additional Questions

Protein Monomer: Amino acids are the monomers for proteins.
Smooth ER Function: Lipid synthesis is the main function of the smooth endoplasmic reticulum.
Cellular Respiration Product: ATP is the molecule produced at the end of the electron transport chain in cellular respiration.
Water Bond: A hydrogen bond forms between two water molecules.
Cellular Respiration Equation: The correct equation for cellular respiration is C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O + ATP.
Buffer Definition: A buffer prevents changes in pH by neutralizing acids and bases.
Prokaryotic vs. Eukaryotic Cells: Prokaryotic cells lack a nucleus and membrane-bound organelles. Eukaryotic cells have a nucleus and membrane-bound organelles. Examples: Bacteria (prokaryotic); Animal cells, plant cells (eukaryotic).
ATP Role in Metabolism: ATP is the primary energy currency in cells and powers cellular metabolic processes. The ATP cycle involves cellular respiration creating ATP and its use in other energy-requiring processes.

Lab Practical Information

Enzyme Lab: This lab examines the activity of the enzyme catalase in breaking down hydrogen peroxide, and factors affecting it are tested.
Photosynthesis/Respiration Lab: This involves investigating the relationship between pH and carbon dioxide concentration in the context of photosynthesis and cellular respiration processes. The organisms and interactions involved in each are also considered.
