24
Q

What activates muscle cell contraction

25
What are thick filaments made of
Myosin
26
Myosin molecule structure
2 tails wrapped into one and 2 heads that swivel
27
2 things that burn to myosin head
Actin and ATP
28
4 proteins in thin filaments
Tropomyosin Actin Nebulin Troponin
29
What binds to Actin binding site
Myosin
30
What binds to Troponin binding site
Calcium
31
What is cross bridge cycle
Myosin head binding to actin
32
What begins cross bridge cycle
When myosin is attached to actin and head is energized by ATP
33
4 steps of cross bridge cycle
Djejjejr
34
Excitation contraction coupling
Process where electrical stimulus causes sacroplasmic reticulum to release Ca and initiate muscle contraction by sacromere shortening
35
Muscle twitch
Single stimulus contraction and relaxation
36
Treppe
Muscle cell stimulated immediately AFTER relaxation
37
Treppe causes
Gradual increase in Ca ions
38
Treppe Result
Subsequent twitched have increased tension
39
Wave Summation
Muscle cell stimulated BEFORE relation phase completely
40
Wave summation result
Muscle can’t relax completely
41
Incomplete/Unfused tetanus
Cell stimulated frequency with NO relation until sub max tension
42
Complete Fused tetanus
Cell stimulated at high frequency (NO RELAXATION) between stimuli reaches max tension
43
Tension produced by muscle depends on 3 factor
Tension generated by individual muscle cell Number of cells in muscle that haven been stimulated Number of contraction proteins
44
Motor unit
All muscle fibers controlled by 1 motor neuron
45
Isotonic muscle contraction
Muscle length CHANGES
46
Isometric contraction
NO change in muscle length
47
2 types of isotonic contraction
Concentric-shortening of muscle (peak muscle tension>resistance) Eccentric-elongation of muscle (peak muscle tension < load)
48
What kind of relationship between muscle contraction speed and load on muscle?
Inverse
49
3 ways muscle returns to normal resting length
Elastic force Opposing muscle contraction Gravity
50
Net gain of ATO for Glycolysis
2 ATP
51
Electric transport chain and Citric acid cycle
30-32 ATP
52
Where does ECE and citric acid cycle take place
Mitochondria
53
Where does glycolysis occur
Cytosol
54
Where does most ATP come from
Oxidative phosphorylation (e- chain)
55
2 Aerobic respiration advantages
32 ATP produced | No lactic acid
