What is common in chlorophyll and haemoglobin?
1) chlorophyll is made from a porphyrin ring structure, similar to heme in hemoglobin 2) chlorophyll is used for energy transfer processes (similar to the cytochrome systems of animals)
Is iron a protein or cell?
Iron is neither a protein nor a cell; it is a chemical element and a metal with the symbol Fe. It plays a crucial role in biological systems, particularly in the formation of hemoglobin, which is a protein in red blood cells that carries oxygen. While iron is essential for various cellular processes, it does not itself constitute a protein or a cell.
What makes gases so toxic?
Obviously not all gases are toxic, but in general, toxic gases tend to be so dangerous because they are gases. It is difficult to contain them once released into the air, and they mix easily with the air, so that even small amounts of a toxic substance are incorporated quickly.
Which organ systems contain the lungs?
The Respiratory System includes the lungs.
What are the transport roles in the biological system?
Transport roles in biological systems involve the movement of substances across cell membranes and throughout organisms. Key examples include the transport of nutrients, gases, and waste products via blood, lymph, and cellular transport mechanisms. Proteins like hemoglobin carry oxygen in the blood, while transport proteins in membranes facilitate the uptake of ions and molecules. This transport is essential for maintaining homeostasis and supporting cellular functions.
What body systems contain hemoglobin?
Hemoglobin (also spelled haemoglobin and abbreviated Hb or Hgb) is the iron-containing oxygen-transport metalloprotein in red blood cellsCardiovascular specifically carries hemoglobin in RBCcardiovascular system...
What systems carries oxygen to blood?
Hemoglobin, contained in red blood cells, carries oxygen to the body's cells via the circulatory system.
What are the causes of the conginital form of mehtemoglobinemia?
One cause is a defect in the body's systems to reduce methemoglobin to hemoglobin. The other cause is a mutant form of hemoglobin called hemoglobin M that cannot bind to oxygen.

Why should the increased affinity of crocodile hemoglobin for bicarbonate ion allow the crocodile to hold its breath for long periods of time?
Like most systems in the body (any body) the oxygen delivery system doesn't work at 100% efficiency - it's just good enough to keep us going. The blood returning to the heart and lungs hasn't given up all the oxygen it carries, just some of it. In crocodiles, as more bicarbonate ions attach to the hemoglobin cell, it loosens the hold on the remaining oxygen, allowing it to be released to be used by the body. So the crocodile hemoglobin/oxygen system is more efficient than a human's, and that lets them go longer without breathing, if they have to.
What factors determine the color of an animal's blood?
Oxygen and hemoglobin. Without oxygen, human blood is blue, and animals with the same colored blood would be blue without oxygen, but since oxygen flows through most animals systems, their mostly red. Besides that of the octopus, which has blue blood due to hemocyanin. The ocelated icefish has a lack of both hemoglobin and hemocynin, leaving its blood clear. The Papua New Guinea skink however has green blood due to the fact that the skink uses biliverdin in its blood, leading it to turn green. Overall, hemoglobin and hemocyanin are the two causes of blood color, along with their byproducts. Hope it helps!
How oxygen becomes availiable to a muscle tissue for respiration?
Oxygen becomes available to muscle tissue primarily through the respiratory and circulatory systems. When we inhale, oxygen enters the lungs and diffuses into the bloodstream, where it binds to hemoglobin in red blood cells. The heart then pumps this oxygen-rich blood through the arteries to the muscle tissues. Once at the muscles, oxygen is released from hemoglobin and diffuses into the cells, where it is used for aerobic respiration to produce energy.
Which two gases are exchanged in the aveoli?
At the aveoli, the blood transfers CO2 and the hemoglobin on red blood cells picks up 02.
What is invloved in breaking up old erythrocytes and disposing o the cellular remains?
Breaking up old erythrocytes (red blood cells) primarily occurs in the spleen and liver, where macrophages engulf and degrade the cells. The heme portion of hemoglobin is converted into bilirubin, which is then processed by the liver for excretion in bile. The iron from hemoglobin is recycled and stored in the body or reused for new red blood cell production. The cellular remains are ultimately disposed of through the body's waste systems.
What is the major buffer system in human blood?
Buffer systems help to maintain constant plasma pH. There are three buffer systems - Protein buffer system, phoshate buffer system and bicarbonate buffer system. Among this, bicarbonate buffer system is the most predominant. Buffers function as "shock absorbers" that accept excess H+ ions or OH- ions and keep blood pH constant. For example, if there is an increase in acidity of blood due to excess HCl (a strong acid), then NaHCO3 (Sodium bicarbonate) will buffer it to a weak acid (H2CO3). HCl+NaHCO3 = NaCl+H2CO3
What is the purpose of a red blood cell?
A major function of the red blood cells is to carry oxygen to all the tissues from the lungs_______________________________________________________________________A red blood cell transports oxygen for respirationRed corpuscles carry oxygen from the lungs to the rest of the body.
