Answer #1

Answer- d. Super-fast

Explanation- Extra ocular muscles are the muscles which cause the movement of the eyeball ( except levator palpebrae muscle which elevates the upper eyelid).Eye movements need to be precise and fast as one needs to change gaze quickly. Levator palpebrae is the fastest muscle. For making this possible, the muscle fibres in these muscles are densely supplied with axons and blood vessels. Also,they contain superfast type of myosin ATPase.

1. When an action potential reaches the T-tubule, it will activate the dihydropyridine receptor at the T-tubule to change conformational shape. Dihydropyridine receptor will trigger ryanodine receptor channel to secrete Ca2+ from the sarcoplasmic reticulum into the cytosol. When action potential is absent, Ca2+ ATPase at the sarcoplasmic reticulum will pump cytosolic Ca2+ into the sarcoplasmic reticulum. Select one: a. True b. False 2. What is TRUE about the myofibril?

Wild type flies have smooth eyes. Seven different true-breeding strains of fly with rough eye phenotype have been identified (A-G). In each strain, the rough eye trait is due to an autosomal recessive allele. To determine how many genes are involved in eye morphology in these flies, complementation analysis is performed between strains. The offspring phenotypes resulting from each cross are observed. (+: wild-type; -: mutant). Based on these data how many genes are mutant in all of these strains...
