Which energy system can power an all-out effort from 3 to 10 seconds? oxygen atp-cp lactic acid nad
Anon25 [30]

The correct option is (b) ATP-CP.

ATP-CP stands for Adenosine Triphosphate Phosphocreatine.

<h3>What makes ATP and ATP CP different from one another?</h3>

ATP exhausts its energy after roughly 1-2 seconds. The high-energy links that hold the CP (creatine/phosphate) molecule together are utilised in subsequent studies. Energy is released when these bonds are broken. ATP is once more formed when the energy is used to rejoin the phosphate to ADP.

<h3>Why is ATP CP so important?</h3>

The ATP-PC system provides energy to the muscle fibers with the highest threshold, which can exert the maximum force. Larger, stronger muscles should have higher power because they can store more phosphocreatine.

Aleonysh [2.5K]

Answer:

c. Cardiac muscle contains bands like skeletal muscle, but its contractions are involuntary like smooth muscle.

Explanation:

In Human anatomy, cardiac cycle can be defined as a complete heartbeat of the human heart which comprises of sequential alternating contraction and relaxation of the atria and ventricles, therefore causing blood to flow unidirectionally (one direction) throughout the human body.

Cardiac muscle is also referred to as myocardium and it's one of the three (3) muscles found only in the heart of vertebrates, the other two (2) being smooth muscle tissue and skeletal muscle tissue.

Cardiac muscle contains bands like skeletal muscle referred to as sarcomeres (contractile units), but its contractions are involuntary like smooth muscle and it's typically being regulated by the sinoatrial node of the heart.
