Fibers are made up of

A

Myofibrils

27
Q

Myofibrils are made up of

A

Thick and thin filaments

28
Q

Myofibrils are made up of

A

Thick and thin filaments

29
Q

When muscle contracts calcium ion bonds to -

A

Troponin

30
Q

Troponin does what

A

It exposes the binding site for the myosin cross bridge to attach to

31
Q

The binding site for the cross bridge are located on

A

Actin

32
Q

Calcium ions are released from ? To initiate muscle contraction

A

Sacroplasmic reticulum

33
Q

When calcium ions are released from the Sacroplasmic reticulum to initiate muscle contraction and are reabsorbed upon muscle relaxation. What happens when calcium ions are not completely reabsorbed

A

The next muscle contraction would be greater than the previous muscle contraction

34
Q

In order to make ATP in muscles, creatine phosphate transfers ? To ADp

A

Phosphate

35
Q

Lactic acid is a by product of

A

Cellular respiration

36
Q

Lactic acid is typically produced during

A

Anaerobic respiration

37
Q

Correct sequence for the production of ATP for muscle contraction

A

CP, anaerobic respiration; Aerobic respiration

38
Q

Functions of ATP in muscle contraction

A

Used to get the cross bridge to bind to actin
Used to get the cross bridge to disconnect from the actin

39
Q

Lactic acid is produced during

A

Glycolysis
And anaerobic respiration

40
Q

Which set of respiration produces the most ATP for muscle contraction

A

Aerobic

41
Q

Which cells convert lactic acid back to pyruvic acid so that pyruvic acid can be used in producing ATP

A

Liver cells

42
Q

Calcium triggers what

A

It triggers the binding of myosin to actin

43
Q

What is a cross bridge

A

Where actin and myosin binds

44
Q

The gap between a neuron and a muscle

A

Synaptic cleft

45
Q

During full muscle contraction which region disappears

A

H region
