Specific antibodies against skeletal music proteins disrupt actin the attachment

Question

Specific antibodies against skeletal music proteins disrupt actin the attachment site for this protein located on which of the following intercalated disc desmosomal junctions tight junctions z- line h-band m-line which of the following regions in a skeletal muscle fiber contains only thick myofilaments and no thin myofilaments z- line A-band H-band in skeletal muscle the T-tubule is located at z- line i-band In Thalassoma bifasciatum , sex change involving the hypothalamo-hypophysial gonad axis only occurs if the L:D cycle is 16:8. The fish are maintained at 12:12 and do not undergo sex change. The best explanation for this is: BA Temperature is also critical B. dopamine levels are two high at 16.8 C. melatonin levels are too high at 16:8 D. serotonin is too high at 16:8 E. melatonin is too high at 12:12 F. NAT levels are too low at 16:8 S A hypothetical compound is developed that reduces addictive cravings for chocolate This compound acts an antagonist to the neucotransmitter KW located in the

Explanation / Answer

1. The answer is D i.e. Z-line because the actins are attached to the Z-disc. Hence, the actin disrupts because the antibody binds to Z-line.

2. Answer is D i.e. H-band. It is the region within A-band where the thick filaments are not superimposed by thin filaments.

3. Answer is B i.e. A-I interface.

4. Answer is A i.e. Temperature is also critical.

5. The compound acts as an antagonist to the neurotransmitter Neuropeptide Y located in the Hypothalamus.
