Answer and Explanation:
In rest, attraction strengths between myosin and actin filaments are inhibited by the tropomyosin. When the muscle fiber membrane depolarizes, the action potential caused by this depolarization enters the t-tubules depolarizing the inner portion of the muscle fiber. This activates calcium channels in the T tubules membrane and releases calcium into the sarcolemma. At this point, tropomyosin is obstructing binding sites for myosin on the thin filament. When calcium binds to the troponin C, the troponin T alters the tropomyosin by moving it and then unblocks the binding sites. Myosin heads bind to the uncovered actin-binding sites forming cross-bridges, and while doing it ATP is transformed into ADP and inorganic phosphate which is released. Myofilaments slide impulsed by chemical energy collected in myosin heads, producing a power stroke. The power stroke initiates when the myosin cross-bridge binds to actin. As they slide, ADP molecules are released. A new ATP links to myosin heads and breaks the bindings to the actin filament. Then ATP splits into ADP and phosphate, and the energy produced is accumulated in the myosin heads, which starts a new binding cycle to actin. Z-bands are then pulled toward each other, thus shortening the sarcomere and the I-band, and producing muscle fiber contraction.
Answer: To me the csi effect is a widely held idea among law enforcement and prosecutors that television series that posses forensic science may want the juror to encourage heavy use of forensic evidence in a case or may want more forensic evidence for convicting criminals of their crimes
Explanation:It could as I’d maybe want people to be properly convicted of their crimes …why ? A lot of people who go to prison are innocent all because of over looked evidence ….why not? Well a cause could be open for too long when ….it’s not that big of an issue
Answer:
The expansion of water upon freezing is vital to life on Earth. It is what causes ice to be less dense as a solid than as a liquid. This means that ice floats in liquid water. ... Water freezes when its molecules are no longer moving around enough to break their hydrogen bonds.
Explanation:
Answer:
Bacteriostatic
Explanation:
The antibiotics are the compounds which are used to treat the bacteria and are of two types: the bacteriostatic and bactericidal.
The bacteriostatic antibiotics are the antibiotics that do not kill the cells but they stop the reproduction of the bacteria and keep them in their stationary phase.
In the given question, since the antibiotic does not kill the cell but stops the doubling that is reproduction therefore the antibiotic is bacteriostatic.
Thus, bacteriostatic is correct.
