Chap 3 Science 7A Flashcards
What is an organic compound
compounds that contain carbon,hydrogen,and oxygen
carbohydrates (di,mono,polisaccharide)
primary energy source in living things
What are lipids made of
1 glycerol and 3 fatty acids
What does a lipid do
stores enegry long term
What are some examples of protiends
amino acid,peptide,dipeptide
what is an enzyme
a protein
what does a nucleic acid do
stored info in a chemical code
What are some examples of passive transport
osmosis and diffusion
What is passive transport
where small molecules or ions move across the membrane without input of energy by the cell
What are some examples of active transport
endocytosis,exocytosis
What is active transport
where big molecules are moved across the membrane through carrier proteins
What is semipermeable membrane
some smaller molecules can get in and out
What does equilibrium mean
even
what is a food chain
a model that shows the flow of energy between several organisms
What is a producer
organisms that make their own food(autotrophs)
What is a consumer
organism that can not make their own food (heterotrophs)
What is a decomposer
organism that break down dead or decaying organisms for energy(heterotrophs)
What is a food web
a model that shows overlapping food chains in an ecosystem
What is an energy pyramid
a model that shows the availability of energy at each trophic level biomass
What are abiotic/biotic factors
non living/living components in a ecosystem
What is a metabolism
all the chemical activities in an organism
What is photosynthesis
The combination of water, carbon dioxide, and sunlight to make glucose and oxygen
What is aerobic respiration
breaking down glucose and oxygen for energy
What is anaerobic respiration/fermentation
breaking down glucose without oxygen for energy
What is biomass
What order does a food chain go in?
producer,primary consumer,secondary consumer,Tertiary consumers,decomposers.
