4 0

Answer:

Changing the equilibrium of the reaction .

Explanation:

Enzymes are bio catalyst that can increase the rate of a bio chemical reaction up to million folds. Enzymes work at optimum conditions of temperature and pH.

The enzymes does not change the equilibrium of the reaction. The enzymes changes the forward and backward rate of a reaction at an equal rate and thus maintains the reaction equilibria.

Thus, the correct answer is option (b).

Lelechka [254]

Answer:

The correct answer is option B.  The contraction forces of the innervated muscle fibers.

Explanation:

Electromyography or EMG is the study of muscle activity with the help of analyzing electric signals that are burst or generated by the contraction of the muscle fibers. In other words, it is the electrical activity of the skeletal muscles in response to a nerve's stimulation of the muscle.

EMG uses the myoelectric signals to analyze muscle that is generated during the contraction forces of the inverted muscle fibers of the skeletal muscle.

Thus, the correct answer is option B.  The contraction forces of the innervated muscle fibers.

The function of chordae tendineae is:
Free_Kalibri [48]

Answer:

The correct answer will be option-E.

Explanation:

Chordae tendinae are the string-like structure in the heart which is composed of dense regular connective tissue called collagen and elastin proteins. They arise from the papillary muscles of the heart and branches out in the ventricle portion of the heart.

These play an important role in the closure of the AV valves to prevent the backward flow of the blood to the atria during ventricular contraction by holding cusps of the valve into the dome-shaped structure.

Thus, option-E is the correct answer.
