Answer:
Carbon monoxide and antimycin are classified as electron transport inhibitors, FCCP as uncoupling agent, oligomycin as ATP synthase inhibitors, and bongkrekic acid as transport inhibitor.
Explanation:
The electron transport inhibitors refers to the substances, which get combine with distinct constituents of the ETC and prevent the function of the carrier. These substances binds with the carrier and prevent its transformation, which eventually results in halting of the process. The most commonly known electron transport inhibitors are rotenone, carbon monoxide, antimycin, etc.
A molecule that prevents oxidative phosphorylation in mitochondria and prokaryotes, or photo-phosphorylation in cyanobacteria and chloroplasts by inhibiting the production of ATP is known as ATP synthase inhibitors. The most commonly known ATP synthase inhibitor is oligomycin.
Similarly to oligomycin, FCCP or trifluorocarbonylcyanide phenylhydrazone is a potent uncoupler or uncoupling agent that prevents the synthesis of ATP by enhancing membrane proton permeability.
Bongkrekic acid refers to a highly toxic transport inhibitor that prevents the ADP/ATP translocase by combining with the inward facing site of ATP-ADP translocase.
Answer:
False
Explanation:
G-Protein Coupled Receptors (GPCR):
GPCRs are transmembrane receptors with three components:
- Extracellular domain for ligand binding
- Seven transmembrane helices
- Intracellular G-protein binding domain
Transmission Through GPCRs:
- A ligand binds to the extracellular domain of the GPCR.
- The GPCR undergoes conformational changes.
- This conformational change activates the G-protein by replacing its bound GDP (guanosine diphosphate) with GTP (guanosine triphosphate).
- The G-protein then loses its GTP bound alpha subunit which activates the adenylyl cyclase system.
Answer:
The cell has an elaborate mechanism in place that check for and correct the mistakes that happen during replication, transcription or translation. This process is called as proofreading. The incorrect nucleotide added during replication cause the replication to be halted for a while. The DNA polymerase enzyme fixes the error and replication then resumes as normal.
Gene mutation, on the other hand, is a permanent change in the DNA sequence that might lead to cancer.
Hope that answers the question, have a great day!
