Can you please answer the following question?
Explain the sliding filament hypothesis for muscle contraction and relaxation
The fate of acetylcholine TOITUWING DAY 10. Describe skeletal muscle fiber contraction including: The sliding filament mechanism Excitation-contraction coupling The cross bridge cycle How muscle fiber contraction results in body movement 11 Describe skeletal muscle fiber relaxation and the resulting relaxation of an entire veletal . SPORTION IS NONNESOTIABLE UN NEGOTIABLE SARONNON NEGOTIABL 14. Define the two abnormal contractions of skeletal muscles, cramp and spasm. 15. Describe muscle tone and state its importance to the health of the muscular system.
According to the sliding filament mechanism of muscle contraction A)the A bands slide in closer between the I bands B)the thin filaments slide inward toward the center of the A band C)the z lines slide in between the T tubules D)the contractile proteins contract, thus shortening the sarcomere E)the filaments slide into the lateral sacs of the sarcoplasmic reticulum
THEORY QUESTION Is the following statement CORRECT or INCORRECT and why? "Fatigue occurs when the muscle is no longer able to generate a force and therefore cannot contract any further" Correct, contraction cannot occur if there is not force generated. Correct, fatigue is solely caused by decreased firing of motor neurons. Incorrect, fatigue has to do with psychology, and nothing to do with the muscle. Incorrect, the muscle contracts in order to generate a force, not the other way around.
a) Explain how set theory relates to probability theory. b) Discuss Kolomogrov's contributions to probability theory. c) What are the axioms of probability and why are they important (in your own words)? Also describe the meaning of axiom.
10) When a muscle fiber enters fatigue, which metabolite below typically does NOT significantly change in concentration? A) ATP B) P G Ca2+ D) Lactic acid E) K* 11) Which is the most accurate definition of a motor unit? A) The mimimum number of muscle fibers required to move a load B) The number of crossbridges formed in a given length of muscle fiber C) The number of muscles innervated by a single nerve D) One motor neuron and all...
According to the sliding filament model, binding sites on actin open when _, allowing the myosin head to bind. calcium ion levels fall creatine phosphate levels rise myosin levels rise calcium ion levels rise ATP levels rise Question 5 2 pts If cardiac muscle cells were prevented from undergoing aerobic metabolism, they ultimately would stop contracting undergo glycolysis synthesize ATP start contracting not be affected
Animal Physiology Question 1. The sliding filament model can describe both how vesicles are moved through a cell as well as locomotion. How can two different processes use the same underlying mechanism? Explain how actin organization differs to allow for these two different processes.
