What else can I help you with?
Rigor mortis occurs at death due to a lack of?
Rigor mortis occurs at death due to the lack of adenosine triphosphate (ATP) in the muscles, which is needed for muscle contraction. When ATP production ceases, the muscles become stiff and rigid, leading to the characteristic stiffening of the body after death.
What happens biologically when you get a muscle cramp?
it is from a lack of water in your body Edited: Because lack of ATP.
What is the name of substance that is the chemical bi-product of turning glucose into ATP and what does it do to your muscles?
Lactic acid. It lets your muscles function with a lack of oxygen (anaerobic respiration instead of aerobic respiration).
When a person dies rigor mortis sets in as atp synthesis ceases why does the lack of atp in muscle cells cause the muscles to become rigid?
The answer is that muscles use ATP to relax, allowing the next part of the contraction process to occur. After death, a lack of energy causes a failure of muscle relaxation on a microsopic level and so a stiffness. Rigor Mortis is caused by lack of ATP which causes tight binding of myosin 2 heads to actin. This doesn't last long, however, as the muscles quickly decompose and become soft again.
During a race how do your muscles produce ATP after the store of ATP in muscles is used?
muscle cells produce ATP by cellular respiration through fermentation
What is the byproduct of ATP and is it bad for muscles?
The byproduct of ATP when it makes muscles work is ADP and energy. They are not harmful in anyway.
How many muscles does ATP have?
The acronym ATP stands for adenosine triphosphate, which is a chemical; chemicals do not have muscles, the just have atoms.
Where do cardiac muscles produce ATP?
Cellular respiration
What does ATP send to muscles?
tell's them what to do
When does energy when you eat food?
When you eat food, chemical energy is converted to mechanical energy. This happens when ATP is supplied to the muscles, enabling movement.
ATP is used by the body as?
ATP is used by the body as a source of energy for the muscles.
Why rigor mortis occurs?
Rigor mortis is caused by the loss of ATP. Oxygen is required for cellular respiration to provide ATP, but once the heart stops pumping, the supply of Oxygen stops. As a result, the muscles begin to decompose and harden. no ATP is available to release attached actin and myosin molecules
