How myoglobin is Distributed in cardiac disorders?
myoglobin
How can oxidation change the colour of meat?
The purplish-red colour of meat is a result of the presence of myoglobin. Iron has an oxidation state of +2 in myoglobin and when it is oxidized to Fe3+ it will produce a brown colour.
What the primary structure of myoglobin?
The amino-acid secquence of myoglobin is the primary structure.
What is another cell organelle that is thought to have originated through endosymbiosis?
Take the mitochondria as example. This organelle contains it's own circular DNA that is representative of cyanobacterial DNA. This DNA codes for some proteins also. Some mitochondrial DNA has been taken into the nuclear DNA where it's presence is rather obvious. And the mitochondria fission in reproducing themselves.
What stores and releases energy for the cell?
ATP stores and transfers chemical energy in cells. The ATP molecule is very important in chemical processes as it will facilitate the energy required.
What gives oxidative muscle fibers their red colour?
Presence of myoglobin
What concept explains the presence of mitochondria in cell?
The concept that explains the presence of mitochondria in cells is the endosymbiotic theory. Mitochondria in cells derived from the extra embryonic membranes.
What color is the cardiac muscle?
The presence of myoglobin gives the muscle tissue its red color.
What determines where energy production will continue into the mitochondria?
The presence of oxygen. Oxygen is needed for mitochondria
Why are slow twitch fibers re in colour and why are fast twitch fibers white?
Presence of myoglobin makes the difference between the two.
How myoglobin is Distributed in cardiac disorders?
myoglobin
What compound stored oxygen inside skeletal muscle cells?
keratinThe correct answer is NOT keratin... the correct answer is myoglobin. This is the oxygen-binding pigment in muscle.
How can oxidation change the colour of meat?
The purplish-red colour of meat is a result of the presence of myoglobin. Iron has an oxidation state of +2 in myoglobin and when it is oxidized to Fe3+ it will produce a brown colour.
what are some exceptions to the cell theory?
Presence of extra-chromosomal DNA: Mitochondria and chloroplasts
How does exercise increase myoglobin stores?
Myoglobin is a protein within the muscle tissue which acts as an oxygen carrier. As a long term effect of exercise. The ability of the muscles to store myoglobin is increased. Because muscles increase their oxidative capacity through regular exercise, the myoglobin stores also increase because they get used to the demands of exercise and work placed upon them so increase stores as they will be needed. The increase in oxidative capacity is achieved by an increase in the number of mitochondria within the muscle cells, an increase in the supply of ATP and an increase in the quantity of enzymes involved in respiration.
What the primary structure of myoglobin?
The amino-acid secquence of myoglobin is the primary structure.
What is nitric oxide myoglobin?
When myoglobin is reduced by nitric oxide through the curing process.
