Communication & Membranes
Type of communication that utilizes the bloodstream
What is Long Distance?
What is the bloodstream/long distance communication?
Another name for protein signal
What is a Ligand?
Feedback loop where the stimulus is amplified
Positive Feedback
Correct order of the four mitosis stages
Prophase, Metaphase, Anaphase, Telophase
An example of this communication is a gap junction
What is direct contact?
The three general stages of signal transduction
What is reception, transduction and response?
Name of the enzyme utilized in protein signaling
What is Adenyl Cyclase?
Feedback loop where the stimulus is counteracted
Negative
Occurs in the S phase
DNA Replication
Neurotransmitters utilize this type of communication
What is synaptic?
The reason why steroid hormones do not utilize cascades
What is hydrophobic/mixes with fats?
The 2nd messenger used in protein signaling
cAMP (camp rock!)
Fruit ripening is seen as an example of
Positive Feedback
Takes up 90% of the cell cycle
What is Interphase?
The biomolecule that is responsible for receiving signals on the outside of the cell
(carbs, lipids, proteins, or nucleic acids)
What are proteins?
Transcription Factors
State the order of the protein signal transduction pathway.
Possible parts (Adenyl Cyclase, ATP, G Protein, cAMP, Ligand, Receptor, and Protein Kinase)
Ligand --> Receptor --> G Protein --> Adenyl Cyclase --> ATP --> cAMP --> Protein Kinase
Difference between receptor and effector
The receptor is body part that picks up the stimuli, and the effector is the body part that takes action
Ex: temperature receptors vs sweat glands
What is Cyclin and CDK?
A molecule in the cell membrane responsible for keeping it fluid in cold temperatures, and solid in hot temperatures
What is cholesterol?
Give two examples of fat soluble hormones
What are testosterone, estrogen, progesterone, cortisol, aldosterone, etc.
Give two examples of water soluble hormones
Epinephrine (adrenaline), Norepinephrine, Thymosin, Melatonin, Calcitonin, and Insulin
Give a reason why the body may be unable to regulate homeostasis?
Genetic Disorders, Drug or Alcohol Abuse, Intolerable conditions (super cold or super hot)
The regulating protein that stays present throughout the cell cycle
