What helps keep our body stable, is self regulating, and necessary for life?
Homeostasis.
Carries out the response.
Effector
adding a phosphate group to a molecule.
Phosphorylation
Converting one type of signal to another in a cell.
Transduction
a molecule that binds to a receptor to send a signal.
Ligand
What is a cellular control mechanism where the activity of an enzyme is inhibited by the end product of a biochemical pathway?
Feedback inhibition
the action a cell, tissue, or organism makes after detecting a stimulus.
Response
Removing a phosphate group from a cell.
Dephosphorylation
What blocks or slows down the normal function of a process of an enzyme or protein?
Inhibitor
A solution with the same concentration as inside the cell; no net water movement.
Isotonic solution
A solution with less solute than inside the cell; water moves in, and the cell swells.
Hypotonic solution
Movement of molecules across a membrane without energy.
Passive transport
Movement of molecules across a membrane using energy.
Active transport
A change in the internal or external environment that causes a response in an organism.
Stimulus
A solution with more solute than inside the cell; water moves out, and the cell shrinks.
Hypertonic solution
the chain of steps that carries a signal inside a cell after the receptor is activated.
Signal transduction pathway
a protein on the cells surface that detects a particular stimulus and triggers a response in the body.
Receptor
