Question

Correct sequence of Breakdown of Energy system are : \[ \begin{aligned} A.&\ \text{ATP} B.&\ \text{Citric acid} C.&\ \text{ADP-CP} D.&\ \text{Oxygen} E.&\ \text{Acetyl-CoA} \end{aligned} \] Choose the correct answer from the options given below :

• A. A, C, E, B, D
• B. A, C, D, B, E
• C. A, C, D, E, B
• D. A, C, B, D, E

Hint:

ATP is the immediate energy currency of the body, while aerobic metabolism involves oxygen, acetyl-CoA, and the citric acid cycle.

Answer 1

The Correct Option is C

Concept: The body produces energy through different metabolic pathways. ATP is the immediate source of energy for muscular activity. During energy metabolism, ATP breaks down and energy systems involving creatine phosphate, oxygen, acetyl-CoA, and the citric acid cycle contribute to continuous energy production.

Step 1: Identify the immediate energy source.
The energy process begins with: \[ \text{ATP} \] which breaks down to release energy.

Step 2: Understand the sequence of energy metabolism.
After ATP utilization, the phosphagen system involving ADP-CP contributes energy. In aerobic metabolism, oxygen is utilized, leading to the formation of acetyl-CoA, which enters the citric acid cycle. Thus, the correct sequence is: \[ \text{ATP} \rightarrow \text{ADP-CP} \rightarrow \text{Oxygen} \rightarrow \text{Acetyl-CoA} \rightarrow \text{Citric acid} \] Hence, the correct answer is: \[ \boxed{(C)\ A, C, D, E, B} \]
