ATPs are the power cell of a cell. Just like a cell, they need to be charged before they can deliver power.
<h3><u>Explanation:</u></h3>
ATP or the Adenosine Triphosphate is a complex molecule containing a Adenine nitrogen base, a ribose sugar and three phosphates being attached with each other in a chain. Adenosine Triphosphate is the power currency of a cell. It just acts like a rechargeable battery. The metabolic and physiological processes of a cell that needs energy, involves the hydrolysis of ATP into ADP and Pi which are Adenosine Diphosphate and Inorganic phosphate respectively.
Now the ATP is discharged and needs to be charged. So the ADPs are charged into ATPs by different processes of respiration like Glycolysis, Kreb's Cycle, Electron Transport Chain etc.
Both the hydrolysis and the condensation of ATP makes the ATP cycle.
Answer:
The correct answer will be option-D.
Explanation:
Calcium plays an important role in muscle contraction as they are released from the sarcoplasmic reticulum after they receive electric impulse.
Calcium triggers the muscle contraction cycle as these calcium ions bind to the troponin-tropomyosin complex. This binding exposes the myosin-binding site on the actin on which high energy myosin binds and cross-bridge is formed.
This cross-bridge formation causes the contraction of the sarcomere and therefore muscle contracts.
Thus, option-D is the correct answer.
