Protein Function
Here is the function of the protein for our bodies:1. Proteins are used for growth and repair of body tissues.
2. Protein is also a precursor chemical compounds such as enzymes that play an important role in regulating a variety of processes that occur in the body.
3. Protein can be a source of energy
4. Regulating the levels of acid-base balance in cells
5. Protein serves as a media propagation of nerve impulses. The protein has a receptor function are formed, such as rhodopsin, a protein that acts as a receptor for receiving or light color on the eye cells.
In addition to the functions mentioned above, the protein also serves as a means of transportation in the body.
Protein as a means of transport
a) Hemoglobin
Hemoglobin is the oxygen-carrying metaloprotein containing iron in the red cells in the blood of mammals and other animals. Hemoglobin molecule consists of globin, Apoprotein, and four heme groups, an organic molecule with an iron atom.
Mutations in these genes lead to a class of proteins hemoglobin decreased disease called hemoglobinopathy, among which the most common is sickle cell anemia and thalassemia.
b) Myoglobin is a small protein (approximately 17,200 daltons) found in cardiac muscle and skeletal muscle, is responsible for maintaining and transferring oxygen from the hemoglobin in the circulation of the respiratory enzymes in the contractile cells. When there is damage to the muscle, myoglobin is released into the blood circulation. Myoglobin is filtered from the blood by the kidneys and excreted in the urine. If a large amount of myoglobin is released into the bloodstream, such as after severe trauma, excessive myoglobin can cause damage to the kidneys and eventually cause kidney failure.
c) Albumin is made in the liver, is the most prominent protein and negatively charged strongest to bind small molecules to be circulated through the blood. Albumin is also useful for maintaining the osmotic pressure of blood.
Hemoglobin (Hb) is a protein molecule in red blood cells that combine with oxygen and carbon dioxide to be transported through the circulatory system to the tissue-tissue in the body. iron ions in the form of Fe +2 in hemoglobin gives red color to the blood. Normally 100 ml of blood contains 15 grams of hemoglobin that can transport oxygen gram 0:03.
BalasHapusI want to ask is how the activity of the hemoglobin level?
For example in people who exercise, whether the transport of oxygen in red blood cells is rapid or fixed as people resume regular activities?
at the time of the exercise, the work becomes a bit heavy because hemoglobin hemoglobin to supply more oxygen. when hemoglobin was not able to work alone saved the lactic acid in the muscles and the muscles will replace a cramp.
BalasHapusI'll try to answer. during exercise muscle energy harusmenghasilkan a process where the oxygen holds a perananpenting. More oxygen means greater use kapasitasmenghasilkan energy and endurance work will mean more great.They that have a high VO2max can do a lot more work before it becomes exhausted, than those with a lower VO2max yangmempunyai. can be summed up in gym hemoglobin oxygen binding process will occur more quickly because of the need more oxygen when we exercise
BalasHapusi will try to answer your question. in people who exercise, work hemoglobin will increase due to the time it takes the body of excess oxygen in the blood due to fatigue.
BalasHapusI'll try to answer the transport of oxygen in red blood cells faster in people who often work in because the person has a very complex motion and will contribute to health.
