Question

Write down the correct sequence of energy system release to muscle :
A.ATP
B.ADP-CP
C.Glycogen
D.Glucose
E.Lactate
Choose the correct answer from the options given below :

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

Hint:

ATP is the immediate energy source for muscles, while glycogen and glucose help sustain continued muscular activity.

Answer 1

The Correct Option is B

Concept: Muscles obtain energy through a sequence of biochemical processes. ATP is the immediate source of energy for muscle contraction. When ATP stores decrease, other energy systems involving creatine phosphate, glycogen, glucose, and lactate participate in energy production.

Step 1: Identify the immediate source of energy.
The first source of muscular energy is: \[ \text{ATP} \]

Step 2: Understand the sequence of energy release.
After ATP utilization, the phosphagen system involving ADP-CP supplies energy. Glycogen stored in muscles is then broken down into glucose, and anaerobic metabolism may produce lactate. Thus, the correct sequence is: \[ \text{ATP} \rightarrow \text{ADP-CP} \rightarrow \text{Glycogen} \rightarrow \text{Glucose} \rightarrow \text{Lactate} \]

Step 3: Choose the correct option.
Therefore, the correct arrangement is: \[ A, B, C, D, E \] Hence, the correct answer is: \[ \boxed{(B)\ A, B, C, D, E} \]
