A high myoglobin means that the heart muscle has been broken down. It can also mean that a heart attack happened. Myoglobin is a protein that can be found in the heart muscle.

What substance in muscle seems able to store oxygen temporarily?

Myoglobin is synthesized in cells and imparts the reddish-brown color of skeletal muscle tissue. Like hemoglobin, myoglobin can combine loosely with oxygen. This ability to temporarily store oxygen reduces a muscle's requirement for a continuous blood supply during muscular contraction.

Can the body survive without myoglobin?

I suppose it cannot. Myoglobin is related to hemoglobin, but has a different oxygen affinity. It is present in your muscles, where it provides oxygen for aerobe glycolysis. Without myoglobin, your muscles would have to resort to anaerobic processing at all times, even at rest, which is less efficient and creates more harmful products that have to be neutralized. Not only would this place a high demand on your liver, it would also make the environment of your largest, most active muscle - your heart. The damage this would do to your heart would eventually lead to heart failure.


How can the oxygen store in myoglobin be replaced after use?

Myoglobin has a very high affinity for oxygen, meaning it binds it very strongly. At very low oxygen concentrations in the cell, myoglobin releases its oxygen, despite the high affinity, simply because there are too few oxygen molecules around to rebind to the myoglobin when they are released naturally from the myoglobin (which usually occurs anyway). Once the oxygen concentration increases again, returning to normal, oxygen molecules will collide with myoglobin. The myoglobin, with its high oxygen affinity, will strongly bind any oxygen that meets it, replenishing myoglobin's oxygen storage very quickly. As myoglobin's affinity for oxygen is stronger the haemoglobin's, it will 'steal' oxygen from haemoglobin in the blood very easily, replacing its bound oxygen. This binding system serves to release oxygen when it is needed if blood oxygen levels are reduced (due to high levels of exercise), but replenishes the supply when oxygen levels begin to rise again.


The function of myoglobin is to?

Basically it binds with oxygen to form oxymyoglobin. when muscles are excercising excessively oxymyoglobin splits and the oxygen is released into the blood to fuel the muscles by assisting in the production of ATP. The main function of myoglobin is to carry oxygen to muscle tissues that have been damaged. Myoglobin is only found in a muscle injury.


Does tuna cause nightmares?

It's possible.The high level of Myoglobin in tuna muscle tissue can cause headaches, nightmares and anxiety in some people.


Why myoglobin has high affinity to oxygen?

Myoglobin has a high affinity for oxygen due to the heme group present within its structure, which can form strong bonds with oxygen molecules. The heme group has a distal histidine residue that stabilizes the bound oxygen molecule, contributing to the high affinity of myoglobin for oxygen. Additionally, myoglobin has a hydrophobic pocket that further enhances its ability to bind oxygen tightly.


What is a fast fiber?

A Fast Oxidative Fiber is a type of muscle fiber with many mitochondria and capillaries. This type has a high myoglobin content. This type of muscle tires more quickly than the slow oxidative fibers and is an intermediate sized muscle. This muscle is good for sprinting and other short, fast-paced activities.
