Study Notes
Protein Synthesis and Cellular Functions
- Ribosomes are the organelles responsible for protein synthesis.
- RNA is single-stranded and contains uracil, unlike DNA.
- The process of glycolysis splits glucose into pyruvic acid.
Reproduction and Genetic Principles
- Meiosis produces sex cells with half the number of chromosomes, while mitosis creates identical daughter cells.
- Hemophilia, a sex-linked trait, shows a predicted ratio of offspring with the disease based on parent genotypes.
- Plants have distinct male (stamen) and female (pistil) reproductive organs.
Plant Biology and Nutrition
- Phloem conducts food through plant stems, while xylem carries water up the plant.
- Photosynthesis can be represented by the equation 6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂.
- The role of decomposition in the carbon cycle is to release carbon dioxide back into the environment.
Taxonomy and Classification
- The scientific name of organisms includes genus and species classifications, e.g., Felis catus for house cats.
- Organisms are classified into kingdoms, phyla, classes, orders, families, genera, and species.
Enzyme Functionality
- Enzyme activity is influenced by physical factors such as temperature and pH, affecting their shape and functioning.
- Enzymes are proteins that act as catalysts, speeding up chemical reactions by lowering activation energy.
Cell Division and Processes
- Interphase is the active phase of cell division where chromosomes replicate.
- Anaphase is when chromosomes separate and migrate to opposite ends of the cell.
- The S phase is characterized by DNA replication.
Cellular Structures and Organelles
- Mitochondria serve as the site of energy production in cells, while vacuoles provide storage.
- The Golgi apparatus is found in protists but not in monerans.
- Lysosomes digest food and break down waste using digestive enzymes.
Energy and Nutrient Cycles
- The energy pyramid illustrates relationships between producers and consumers.
- Gymnosperms have seeds without protective coverings; examples include red cedar and coniferous trees.
- Nitrogen in the soil is utilized by green plants to synthesize proteins.
Membrane Transport and Osmosis
- Active transport requires ATP to move substances across membranes, while osmosis involves the movement of water across semi-permeable membranes.
- Water concentration affects cell behavior, as seen in hypotonic solutions leading to cell swelling.
Symbiotic Relationships
- In symbiosis, mutualism benefits both organisms, while commensalism benefits one without affecting the other. Parasitism benefits one at the expense of the other.
- Bacteria and blue-green algae are classified together as prokaryotes.
Light Absorption and Photosynthesis
- Chlorophyll reflects green light, absorbing primarily blue and red light for photosynthesis.
- The least effective light color for photosynthesis is green.
- Light is necessary for photosynthesis, and blue light is most effective for growing plants indoors.
Evolution and Ecosystem Dynamics
- Fragmentation allows sponges to reproduce asexually when torn into pieces, each developing into a new organism.
- Pathogens are infectious organisms that spread disease.
