You coat microfilaments with the myosin S1 fragment and add these coatedmicrofilaments to the slide with Protein Y stuck on a slide. You observe the coatedmicrofilaments move, and they move in the direction with the barbed ends leading.Your advisor is ecstatic with this observation, telling you that you have made a majordiscovery.

Describe the movement of myosin along an actin filament. Outline the primary molecular steps and explain how this process is used by cells. How many actin monomers within an actin filament would a myosin molecule need to ratchet in order to contract a cell by approximately 1 um? How fast could a non-muscle cell make this contraction compared to a muscle cell if the relative rates of myosin walks on F-actin are 4.5 um/sec and 0.04 um/sec for myosin II and I respectively?
Why is myosin II the only myosin capable of producing contractile force?

MYK-461 is also hypothesized to a) stabilize a head-head interaction in two-headed cardiac myosin. b) inhibit skeletal muscle myosin shortening. c) prevent myosin binding protein C from regulating actin-activation of cardiac myosin. d) accelerate ADP release, but only in the absence of actin. e) disrupt the OFF state of the thick-filament.

You are studying a Drosophila protein called FROZN that you think is a vesicle snare that plays a role in exocytosis of synaptic vesicles containing acetylcholine at the neuro-muscular junction. Because this protein has been isolated from neuromuscular junctions, you hypothesize that this snare is a Ca+2 sensor that mediates the final merging of vesicles with the membrane. To test this hypothesis you perform 2 experiments: 1. You make a mutant Drosophila that lacks FROZN and find that synaptic vesicle release at the neuromuscular junction is blocked. 2. You block Ca+2 entry into the presynaptic neuron terminal in a normal (wild type) fly and find that synaptic vesicle release is blocked. Do these experiments support your hypothesis that FROZN is a vesicle snare and is the Ca+2 sensor? Is there another possible explanation for the function of FROZN? Explain your answer.
Describe the position where wrist and finger are in full extension. What sensation will be felt in this position? What explains this sensation that you felt when the wrist and fingers were positioned in extension? *NOTE: Apply any of the following concepts to the explanation as deemed appropriate and connected to the situation above: Mucle Contraction, Concentric Contraction, Isometric Contraction, Eccentric Contraction, Force Velocity Curve, Stretch Reflex, Reciprocal Inhibition, Autogenic Inhibition, Length-Tension Relationship
It is not an easy matter to assign particular func-tions to specific components of the basal lamina, sincethe overall structure is a complicated composite materialwith both mechanical and signaling properties. Nidogen,for example, cross-links two central components of thebasal lamina by binding to the laminin γ-1 chain and totype IV collagen. Given such a key role, it was surprisingthat mice with a homozygous knockout of the gene fornidogen-1 were entirely healthy, with no abnormal phe-notype. Similarly, mice homozygous for a knockout of thegene for nidogen-2 also appeared completely normal. Bycontrast, mice that were homozygous for a defined muta-tion in the gene for laminin γ-1, which eliminated just thebinding site for nidogen, died at birth with severe defectsin lung and kidney formation. The mutant portion of thelaminin γ-1 chain is thought to have no other functionthan to bind nidogen, and does not affect laminin struc-ture or its ability to assemble into the basal lamina.…
