- BNa + ions depress the activity of muscle enzyme.
- CK + ions permit the heart muscles to relax between the beats.
- DNa + is especially an enzyme activator.
Correct answer
D. Na + is especially an enzyme activator.
Step-by-step solution
Correct statements are: 1 . Sodium ion is the major cation in the blood plasma of vertebrates. 2 . Na + ions depress the activity of muscle enzyme. 3 . K + ions permit the heart muscles to relax between the beats. Incorrect statement is: Na + is not especially an enzyme activator. It helps to keep the water and electrolyte balance of the body. Sodium is also important in how nerves and muscles work
