| (A) The accumulation of pyruvic acid in die muscle causes fatigue. |
| (B) ATP is resynthesized in the muscle by the phosphorylation of ADP by a phosphogen. |
| (C) Cori and Cori cycle occurs in the muscles, |
| (D) The phosphogen in the vertebrate muscle is arginine phosphate. |
A) A and D
B) B and D
C) C and D
D) B and C
Correct Answer: D
Solution :
The ATP is actively and continuously replenished by energy rich muscle phosphogen. In muscles the pyruvic acid produced by glycolysis is transformed intolactic acid in absence of oxygen. In the liver80% of lactic acid resynthesized glycogen by a process called Cori cycle.
