BIOD 101 Module 5 Questions AndAnswers With Verified Solutions 100%
Correct Latest Updated 2024
Ligand - ANSWER✔✔ is a molecule that has specificity for a given receptor, and
the binding of a ligand to the given receptor causes a change.
there is a wide array of cell ligands: hormones, peptides, sugars, and even small,
hydrophobic molecules.
regardless of its type, a ligand is always specific for the target receptor.
this ligand-to-receptor specificity helps to regulate responses in the target cell
while not impacting non-target cells that may be in the same location.
Intercellular Communication - ANSWER✔✔ when the sending cell releases a
ligand and the target cell receives the "message"
(inter = between cells)
Five main types of intercellular signaling: - ANSWER✔✔ 1. paracrine signaling
2. synaptic signaling
3. autocrine signaling
4. endocrine signaling
5. direct cell-to-cell signaling
, Paracrine Signaling - ANSWER✔✔ is a type of local range signaling, meaning the
signal travels over a short distance.
a signaling cell will release vesicles containing the signaling ligand, and the ligand
will then bind to nearby target cells.
this type of signaling occurs in many types of cells and tissues, and it is of great
importance during development and for the secretion of growth factors.
Synaptic Signaling - ANSWER✔✔ is another form of local range signaling, but it
occurs across a synapse.
the pre-synaptic cell is a neuron containing molecules to be released, and the post-
synaptic cell may be another neuron or a muscle cell.
an electrical signal is propagated down the pre-synaptic cell and stimulates the
release of neurotransmitters.
neurotransmitters diffuse across the synapse and bind to the target cell.
Synapse - ANSWER✔✔ a small gap between the signaling cell (also called the
pre-synaptic cell) and the target cell (also called the post-synaptic cell).
Neurotransmitters - ANSWER✔✔ a class of ligand molecules that are released
from neurons, that are packaged in vesicles.
neurotransmitters have a rapid action and bind quickly to their target cell to cause a
change in the target cell.
