What role do ligands play in the alteration of gene expression? -
ANSWER-Ligands may alter the processes of transcription and/or
translation resulting in changes to gene expression.
Fill in the Blank in the following paragraph describing the signaling
pathway.
Signaling begins when an extracellular ___________ binds to a
receptor anchored within the plasma membrane. Relay molecules
and scaffolding proteins ___________ the signal to activate a
cellular response. - ANSWER-1. Ligands
2. Transduce
Once inside the intestinal walls, what does v. Cholera bacterium
produce that bind to a GPCR, causing the target cell to be
permanently activated? - ANSWER-The V. Chlolera bacterium
,2|Page
produces an EXOTOXIN that binds to the GPCR, preventing it
from hydrolyzing GTP to GDP.
When a signaling ligand binds to the extracellular binding region
of an RTK, what happens THIRD?
1. Dimerization of individual monomers.
2. Inactive relay proteins become activated.
3. Auto-phosphorylation. - ANSWER-Inactive relay protein
become activated.
The target cell is considered:
1. Pre-synaptic.
2. Post-synaptic.
, 3|Page
3. A synapse.
4. A neurotransmitter. - ANSWER-Post-synaptic.
Explain how the activation of mitochondrial proteins induce
apoptosis. - ANSWER-Upon activation of these proteins, a
conformational change occurs, allowing these proteins to form
tiny, molecular pores. The resulting pores cause the mitochondrial
outer membrane to leak, which releases other pro-apoptotic
proteins which work to degrade and disassemble the inner
contents of the cell.
Which of the following is/are true regarding ligand-gated ion
channels? (Select all that apply).
- They allow the passage of ions and acts as a receptor.
- The binding of a ligand causes the channels to open.
- The lumen of the channel is hydrophilic.
