Question

Use the following response which id most closely related

Skeletal muscle requires ____ for contraction

Smooth muscle requires ____ for contraction

Cardiac muscle requires ____ for contraction

All muscle require ___ for relaxation

Neurons require____ for exocytosis of transmitters

Neurons stimulate this ___ event in all innervated muscle

A. Calcium must bind to calmodulin

B. Calcium must bind to troponin

C. A calcium dependent protein kinase must be activated

D. Calcium must be actively transported into the sarcoplasmic reticulum

E. None of the responses is an appropriate match

Answer 1

1 For skeleton muscle contraction Calcium must bind to troponin

2 for smooth muscle contraction Calcium must bind to calmoduli to start a cascade in smooth muscle

3 for cardiac muscle contraction cAMP-dependent protein kinase A in activation of a voltage-sensitive release mechanism for cardiac contraction

4 for relaxation of muscle Calcium must be actively transported into the sarcoplasmic reticulum

5 for exocytosis of transmitters neuron requires calcium because it is a vital element in the process of neurotransmitter release

6 neurons stimulate action potential in all innervated muscle
