Mrs. Losoya ACP Review Flashcards
Mutualism
Both species benefit.
Ex- Bees and Flowers
Commensalism
One species benefits the other is not affected
Ex- Whale and Barnacle
Parasitism
One species benefits the other is harmed
Ex- Dog and a Tick
Predation
One species benefits the other is killed
Ex- Lion and Gazelle
Competition
Both species are harmed competing for resources
Ex- Two male deer competing for a female
Carbon Cycle Sources
Respiration and Combustion (uptake through photosynthesis)
Levels of Organization
Organism Population Community Ecosystem Biome
Eutrophication
Excess nutrients deplete oxygen levels in lakes and ponds
Greenhouse Effect
Excess carbon gets trapped in the atmosphere and heats up the earth
Biomolecules
The four molecules of life: Carbohydrates, Lipids, Nucleic Acids, and Proteins
Nucleic Acid
Stores genetic information. Example- DNA and RNA
Monomer: Nucleotide
Carbohydrates
Quick energy for animals, makes up the cell wall in plants.
Monomer: Monosaccharide
Monosaccharides
Simple sugars or 1 sugar (Ex- candy)
Polysaccharides
Complex or many sugars (Ex- Starches)
Lipids
Used for long term energy storage, insulation, and hormones
Monomer: Glycerol and Fatty Acids
Protein
NOT used for energy unless needed. Forms structural component of cells, enzymes
Monomer: Amino Acids
Nucleotide
Monomer of Nucleic Acid. Composed of a 5-carbon sugar, nitrogen base, and phosphate.
Enzymes
Speeds up chemical reactions by lowering activation energy
Factors that Effect Enzymes
pH, temperature, amount of substrate, and presence of an inhibitor
Enzyme Inhibitors
Competitive- Binds at the active site to prevent the substrate from attaching
Noncompetitive (also called allosteric)- binds somewhere other than the active site but changes the shape of the enzyme so nothing can fit together
Prokaryote
Oldest Cells, Bacteria, Don’t have nucleus or membrane- bound organelles
