Question

5. Resolution of rigor mortis starts three days after death, the possible reason is?
A. Lactic acid fermentation B. Decreased temperature C. Release of phosphor-creatin D. Decomposition​

Answer 1

Answer:

The correct answer is option D) Decomposition

Explanation:

• Decomposition of the body initially starts with Rigor mortis.
• Rigor Mortis is a condition that occurs after death in which the muscles get stiffened due to the depletion of ATP's.
• It starts to appear approximately 2 hours after death and starts to disappear only after 36 hours of death.
• This is because the actin-myosin complexes formed start to disintegrate due to the occurance of proteolysis, thereby causing the dissolution of stiffened muscles.

Answer 2

The answer of all the question

Explanation:

• Rigor mortis is a recognized sign of death, caused by the chemical changes in muscles after death. causing the whole body too stiff & lock in place, making it difficult to move.

• It starts after about 3 to 4 hours of death, reaches maximum stiffness in 12 hours.

• After death, respiration in an organism stop, oxygen availability gets decreases. ATP is required to cause the separation of the actin-myosin cross-bridges during the relaxation of the muscle. When oxygen is not available, the body continues to produce ATP via anaerobic-glycolysis.  

• So, the correct option is A
