A50-ml crude extract of skeletal muscle contains 32 mg of protein per ml. ten μl of the extract catalyzes a reaction at a rate of 0.14 μmol product formed per minute. the extract was fractionated by ammonium sulfate precipitation, and the fraction precipitating between 20% and 40% saturation was redissolved in10 ml. this solution contains 50 mg/ml protein. ten μl of this puriﬁ ed fraction catalyzes the reaction at a rate of 0.65 μmol/min. (a) what is the degree of puriﬁ cation (fold puriﬁ cation)? (b) what is the percent yield of the enzyme recovered in the puriﬁ ed fraction?
b. the change in body structure is caused by contraction of muscles compressing the watery body fluid.
The hydrostatic skeletons utilize the fluid filled cavity for locomotion as the fluid or water is incompressible, so the muscles contraction will become smooth and organism can apply force on the fluid cavity to change the shape of the body to facilitate the locomotion.
The worms have the rings of muscles that are filled with water this makes the whole body hydrostatic in nature that facilitates the smooth movement.
Proteins are the major components of the body and it helps in building blocks of the muscles as well as other components of the body.
The protein in the muscles plays a major role in gene replication as it helps in giving instructions for the further protein synthesis.
This property of protein helps in the growth of the muscle in the body. It enables the muscle cells to grow which helps in the overall growth and building muscle.
People generally have two types of skeletal muscles fibers: slow twitch and fast twitch. Slow twitch muscles functions by providing long endurance feats. Example for distance running.
The slow twitch muscles fatigue helps in providing fatigue faster but it is used in the powerful busts of movements example: sprinting.
Most of the body's skeletal system contains both types of muscles: soft twitch and fast twitch.
a. suckling by young
e. anterior pituitary
f. mammary glands
g. milk production
c) 50% there are four chromosomes. after crossing over, 2 of the four have been changed. that means any gamete has a 2 in 4 chance or 50% chance of receiving the mutated chromosome.
