metabolism the total of an organism's chemical reactions; an emergent property of life that arises from interactions between molecules within the orderly environment of the cell
What is metabolism

_____________ ______________ is an incomplete chronicle of evolutionary change
What is fossil record
100
hormone-secreting organs
What is endocrine glands
100
A transmembrane protein that helps a certain substance or class of closely related substances to cross the membrane
What is transport protein
100
the basic structural and functional unit of all organisms; they may exist as independent units of life
What is cell
200
a metabolic process that breaks down complex molecules into simpler compounds; example = cellular respiration because it breaks glucose into carbon dioxide and water; the energy that is stored becomes available to do work within the cell
What is catabolic pathway
200
the general term for chloroplasts and related organelles
What is plastids
200
group of proteins secreted by different cell types like T cells and macrophages.
What is cytokines
200
The difference in electrical charge (voltage) across a cell's plasma membrane due to the differential distribution of ions. Membrane potential affects the activity of excitable cells and the transmembrane movement of all charged substances
What is membrane potential
200
eukaryotic kingdom that includes organisms that absorb nutrients after decomposing organic material
What is Fungi
300
he study of how energy flows through living organisms
What is bioenergetics
300
supercontinent that existed 250 million years ago; habitat loss and species extinction, lower sea level
What is Pangaea
300
region on the underside of the brain that recieves signals and initiates endocrine signals.
What is hypothalamus
300
An active transport protein in a cell membrane that uses ATP to transport hydrogen ions out of a cell against their concentration gradient, generating a membrane potential in the process
What is proton pump
300
a taxonomic caregory above the kingdom level
What is domain
400
the use of an exergonic process to drive an endergonic one; ATP is responsible for mediating this, and it acts as an energy source
What is energy coupling
400
between Mesozoic and Cenozoic eras; iridium found from crater or meteorite that hit near Yúcatan, covering the sun and disrupting climate patterns for quite a few years; includes dinosaurs' extinction
What is Cretaceous mass extinction
400
made by anterior pituitary; stimulates gonad activity
What is FSH
400
Open channels in the cell wall of a plant through which strands of cytosol connect from an adjacent cell
What is plasmodesmata
500
the state of a molecule when it receives a phosphate, such as in ATP hydrolysis, making it more reactive (less stable) than the original molecule
What is phosphorylated
500
process in which Earth's continents drift across the planet's surface on great plates of crust that float on the hot,
underlying mantle; leads to allopatric speciation
What is continental drift
500
steroid derived molecule obtained form food, synthesized by skin.
What i s Vitamin D
500
control shape of stomata, control water uptake/loss, open day/close night
What is guard cells
500
a type of logic in which generalizations are based on a large number of specific obserations
