Flashcards in Internal/External Stimuli Deck (25):
These are chemical signals that are produced WITHIN the body and move from one location to another.
These are a variety of physical and biological stimuli produced OUTSIDE of the body.
Received signals that activate intracellular pathways that lead to cellular responses.
What are the THREE (3) stages of SIGNAL TRANSDUCTION?
This is the conversion of one form of energy to another.
This STAGE of SIGNAL TRANSDUCTION is the process by which a signal ACTIVATES.
These are PROTEINS that become ACTIVATED when they receive a SPECIFIC signal.
What are TWO (2) LOCATIONS of RECEPTORS?
Plasma Membrane (WATER SOLUBLE)
Intracellular (NOT water soluble)
These are SMALL MOLECULES and IONS inside of the cell that AMPLIFY signal from RECEPTOR and TRANSFER signal to EFFECTORS.
What are the the FOUR (4) STAGES of the SECONDARY MESSENGER SYSTEM?
1.) HORMONE BINDS to receptor
2.) RECEPTOR ACTIVATES G protein
3.) ATP CONVERTED into cAMP
4.) cAMP ACTIVATES kinases
This is the ACTIVATION of EFFECTORS which will REGULATE one or more CELLULAR ACTIVITIES.
What are TWO (2) types of CELLULAR RESPONSES?
Post Translational Modification
This is the interaction between internal and external stimuli.
This is the receptor to the signal of light.
This is the plant growth response in light.
This is a CHEMICAL SUBSTANCE which REGULATE the METABOLIC FUNCTION of target cells.
That THREE (3) things to plant hormones generally affect?
This is the MASTER plant HORMONE that influence plants throughout their LIFETIME.
What are the major functions of auxin (3)?
Lateral and Adventitious Root Growth
Phototropism and Gravitropism
Where are auxins PRODUCED (3)?
Apical meristems of ROOTS and SHOOTS
Developing seeds and fruits
Where are auxins transported (2)?
These work in concert with auxins to CONTROL CELL DIVISION, DIFFERENTIATION and APICAL DOMINANCE.
These are involved in the SLOWING GROWTH of plants.
This triggers FRUIT RIPENING.
