Discuss whether the sarcomere length increased, decreased or stayed the same in muscle fibers from
a). 0.25% ATP distilled water
b). 0.25% ATP, 0.05 M KCL, 0.001 M MgCl2
c). 0 ATP, 0.05 M KCL, 0.001 M MgCl2
Homework Answers
1. The sarcomere length decrease or contract in third test tube because glycerinated muscle contracted in presence of ATP and without ATP, activation of myosin head in muscle is not possible. Mg ions interfere with muscle contraction in case of live tissue but in glycerinated tissue , MgCl2 and KCl solution addition to ATP increases the muscle contraction due to mysosin's high compatibility to these ions.

In each case indicate whether the quantity in question increased, decreased or stayed the same when the string length is increased. Assume that the tension is unchanged. The function generator is kept at the same frequency, and the string is in resonance in all cases. Wavelength: Fundamental frequency: Fundamental wavelength: Wave speed:

Question in the picture
smooth pipe: Total length, L Diameter, d -25 mm 4 m tank water (pa 1,000 kg/m3, μ 0.001 kg/ms) flows from a very large tank (that is open to atmosphere) through an L 4 m total length of smooth pipe of d = 25 mm diameter at a bulk velocity of 6 m/s. The water then exits the pipe at 3 m above ground as a free jet. The pipe network contains a gate valve (V),...

QUESTION 4 (25 marks) Water (Cr 4.208 kJ/kg.K) at flow rate of 5.11 kg/s s heated from 78°C to 98°C in an economizer inside a boiler. The boiler is a cross flow heat exchanger with single pass, shell fluid mixed and other fluid unmixed. The average water velocity in the 1.5 cm diameter (D) tube is 1.27 m/s. On the shell side, hot air (C,-1.0341 kJ/kgK) was used as the heating fluid with 7.3 kg/s of it entering the exchanger...
