Study Notes
Quiz Instructions
- Prepare for the midterm by reviewing the textbook and PowerPoint materials.
- Reread content multiple times for better retention of definitions, diagrams, and relationships.
Cell Events and Types
- Eukaryotic cells engage in processes such as protein synthesis and Krebs cycle.
- Prokaryotic cells primarily perform glycolysis and some types of cellular respiration.
- Both eukaryotic and prokaryotic cells conduct cellular respiration.
- Hypertonic, hypotonic, and isotonic environments influence specific cellular processes like osmosis and diffusion.
Cell Membrane Characteristics
- Phospholipid structure of the cell membrane regulates polar molecule movement.
- The membrane restricts passage of water-soluble molecules while allowing nonpolar molecules to pass freely.
- Cholesterol maintains membrane fluidity.
- Transmembrane proteins facilitate molecular transport across the membrane.
Energy Storage Types
- Chemical energy is stored in molecular bonds.
- Kinetic energy involves the movement of molecules.
- Potential energy is associated with the position of objects.
- Mechanical energy includes stored energy from broken-down molecules.
Photosynthesis Products
- Light-dependent reactions of photosynthesis produce ATP, NADPH, and oxygen.
- Glucose is synthesized during the light-independent reactions.
Energy Classification of Organisms
- Chemotrophs derive energy from oxidizing organic compounds.
- Heterotrophs consume organic material for energy.
Cellular Structures
- Cell structures include the cell wall, plasma membrane, cytoplasm, nucleoid, ribosomes, and flagella.
Organelle Functions
- Organelle descriptions include:
- Smooth endoplasmic reticulum primarily consists of lipids.
- Rough endoplasmic reticulum has ribosomes for protein synthesis.
- Mitochondria produce ATP by harnessing energy.
- Lysosomes breakdown cellular debris.
- Nucleus stores DNA and cell chromosomes.
- Golgi apparatus modifies and exports ER products.
Algal Cell Functions
- Algal cells in water are primarily engaged in photosynthesis.
Bond Strengths
- Covalent bonds are the strongest and most stable.
- Ionic bonds play a crucial role in DNA and amino acid structure.
- Hydrogen bonds are weak but essential in enzyme-substrate complex formation and occur in water molecules.
