Final Flashcards
Carbohydrates
Main source of energy for organisms
Monosaccharide and Polysaccharide
C, H, O2
Lipids
Used to store energy
Fatty acid and fatty acid chain
C and H
Proteins
Control reaction rates/regulate cell processes
Amino acids and polypeptides
N, H, C, O2
Nucleic Acids
Store and transfer genetic information
Nucleic acids and nucleotides
N, H, C, P, O2
Cellulose
Polysaccharide for plants, gives plants strength and rigidity
Chitin
Cell walls of fungi
Substrate
Reactants of enzyme-catalyzed reactions
What allows water to bond easily with other polar and water molecules?
Water molecules are polar
Decomposer (Saprobe/Saprophyte)
Eats dead decaying matter
Detritivore
Feeds on detritus particles
Symbiotic relationships
Any relationship in which 2 organisms live closely together
Parasitism
One organism is harmed while one organism benefits
Mutualism
Both organisms benefit
Commensalism
One organism benefits while one organism is not harmed nor benefitted
What is the difference between a food chain and food web?
Food chains show the steps in which organisms transfer energy by eating and being eaten, food webs are a network of feeding interactions
What is a trophic level?
Each step in a food chain or web
Nucleus
Stores DNA of the organism
Mitochondrion
Powerhouse of the cell
Ribosome
Produce protein by following code from DNA (found in cytoplasm)
Lysosome
Breaks down and recycles macromolecules
Cell membrane
Regulates materials entering/exiting cell
Chloroplast
Converts solar energy into chemical energy stored in food
Endoplasmic Reticulum (smooth)
Lipids, proteins, and other materials exported from the cells are made
Endoplasmic Reticulum (rough)
Protein synthesis
Golgi apparatus
Modifies, sorts, and packages proteins to send out of the cell
Cell wall
Shapes, supports, and protects the cell
Vacuole
Stores materials
Diffusion
Movement of molecules from high concentration to low concentration
Osmosis
Movement of molecules from low concentration to high concentration
Active transport
Movement of materials across cell membrane with cellular energy
Isotonic
Balanced
Hypotonic
More water outside the cell
Hypertonic
More water inside the cell
Plasmolysis
When a cell loses water due to a hypertonic solution
Passive transport
Movement of materials across cell membrane without cellular energy
Cytolysis
The bursting of a cell due to a hypotonic solution
Contractile vacuoles
A vacuole that expels excess liquid
What is the equation for photosynthesis?
6CO2 + 6H2O (sun) C6H12O6 + 6O2
What is the equation for cellular respiration?
C6H12O6 + 6O2 (sun) 6CO2 + 6H2O
