Study Notes
Lipids and Enzymes
- Lipids are characterized by their insolubility in water.
- Proteins can assist in digesting cholesterol, converting it to energy.
- Enzymes accelerate chemical reactions by lowering activation energy.
Nucleic Acids and Cells
- DNA and RNA are both made up of nucleotides.
- Enzymes are proteins essential for homeostasis in organisms.
- Cell membranes serve as barriers to regulate entry and exit of substances.
- Prokaryotic cells lack a membrane-bound nucleus, unlike eukaryotic cells.
Cellular Structure and Energy
- Muscle cells have numerous mitochondria due to high energy demands.
- Plant cells are distinct for containing chloroplasts, unlike animal cells.
- Ribosomes are essential for protein synthesis; their absence prevents this process.
Transport Mechanisms
- Osmosis refers to the movement of water across membranes, impacting saltwater fish in freshwater.
- Passive transport does not require energy; active transport does.
- Facilitated diffusion allows large molecules to enter cells without energy expenditure.
- The selectively permeable membrane maintains homeostasis by controlling substance movement.
Photosynthesis and Cellular Respiration
- Pigments are vital for photosynthesis as they absorb and reflect light.
- Photosynthesis provides energy for plants; cellular respiration converts glucose into energy.
- ATP is crucial as the energy currency for cellular processes.
Genetics and Cell Division
- Genotype refers to genetic makeup, while phenotype describes physical characteristics.
- Mitosis involves the division of the nucleus, ensuring each daughter cell has a complete DNA set.
- Meiosis reduces chromosome numbers, generating genetic variation.
- Nondisjunction occurs with improper chromosome separation during cell division.
DNA Structure and Function
- DNA comprises nucleotides, with deoxyribose as a sugar and a particular nitrogen base sequence coding for traits.
- The backbone of DNA consists of sugar and phosphate groups, linked by hydrogen bonds.
- Complementary strands of DNA pair adenine with thymine, and guanine with cytosine.
Evolution and Natural Selection
- Natural selection is illustrated by antibiotic resistance, where surviving bacteria reproduce.
- Camouflage aids survival and reproductive success in species.
- Speciation can occur when populations are geographically isolated, preventing interbreeding.
Ecosystems and Relationships
- Mutualism, commensalism, and parasitism are forms of symbiotic relationships between organisms.
- Abiotic factors, like water and soil, shape ecosystems alongside biotic factors like organisms.
- Energy transfer in ecosystems follows the 10% rule, with most energy lost as heat while elevating trophic levels.
Classification and Organization
- The genus represents the most specific classification in taxonomy.
- Different kingdoms include Plantae, Protista, and Fungi, varying by cellular structure, function, and organization.
- Scientific names provide clarity in identifying organisms, unlike common names.
Viruses and Fungi Relationships
- Viruses reproduce only inside host organisms, while their surface projections facilitate invasion.
- Fungi and plant roots develop a mutualistic relationship, exchanging nutrients and minerals.
Limitations and Survival
- Resource limitations in an ecosystem can jeopardize the long-term survival of species.
