Ap Exam Big Idea: Biological Systems Interact Flashcards
Non competitive inhibition
When the inhibitor binds to the alloseric site changing the shape/confirmation of the enzyme
Feedback inhibition
When the end product of an enzyme catalyzed reaction works to block the original enzyme
Root hairs
Increase surface area of roots to bring in more water
Stomata
Opening of leaves that allow diffusion of carbon dioxide water and oxygen
Guard cells
Open and close the stomata
Primary plant growth
Upward growth
Secondary plant growth
Outward growth
Xylem tissue
Transports water throughout the plant using spiral tubes - vascular tissue
Competitive inhibition
When the inhibitor and substrate compete for the active site
R selected species
Many offspring, no parental care - many die young
K selected species
Few offspring lots of parental care, offspring live a log time
Density independent factors
Affect populations regardless of how many individuals are in the population at the given time
Density dependent factors
Increase as the number of individuals in a population increase
Primary producers
Autotrophs
Primary &a secondary consumers
Eat autotrophs
