[CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
|
A calcium deficiency would
|
|
create uncoordinated muscle contractions
|
|
|
allow muscle contraction, but not relaxation
|
|
|
prevent contraction by preventing myosin from binding to actin
|
|
|
have no effect on contraction
|
Explanation:
Detailed explanation-1: -Because calcium helps with muscle contraction, low levels of the mineral means you might experience more muscle cramps than usual, Kang says, specifically in your back and legs. Other symptoms include brittle fingernails, bone-related injuries, irregular heartbeat and tingling in arms and legs.
Detailed explanation-2: -Calcium diffusing in the cytoplasm between myosin and actin filaments of the muscle fibrils causes the filaments to slide into each other, triggering the contraction of the entire muscle fiber.
