Red blood cells contain the substance haemoglobin, which is an iron-based molecule that binds to oxygen molecules for transport around the body.
Spider blood is usually blue due to the presence of the copper-based molecule hemocyanin, which helps transport oxygen throughout their bodies. Hemocyanin turns blue when it binds with oxygen, giving spider blood its distinctive color.
Spiders have blue blood. In human blood oxygen is bound to hemoglobin which contains iron, giving it the blood a red color. In spiders, as well as other Arthropods and Molluscs, oxygen is bound to hemocyanin which contains copper, giving its blood a blue color. The same interaction that causes oxygenated blood to color, also causes iron rust to appear reddish and the oxidized copper to appear green. However, I have noticed no color in spider blood before.
Since squids do not have haemoglobin they use haemocyanin to bind and transport oxygen throughout their body.
The main reason we need blood is to transport oxygen from our lungs to other parts of our body. Humans and other animals use a molecule called hemoglobin to pick up and deliver oxygen. Hemoglobin is a very large molecule but since bugs are so small and don't need so much oxygen they use a simpler molecule called hemocyanin.The reason that the blood is of different color is that the molecules contain two different metals:# Hemoglobin in humans contains iron. When you leave something made of iron outside for a long time it rusts. Rust is red as you have probably seen. # Hemocyanin in bugs contains copper. When copper is left outside it patinates. Patina is green (look at the statue of liberty). Both rust and patina is a sign that the metal has picked up oxygen.
Your lungs refine oxygen from the other gases in air because the gases diffuse through the cell walls in the alveoli in your lungs through osmosis (higher concentration of gases in the air than in the blood, so gases move from the higher concentration to the lower concentration) where they contact the red blood cells. The hemoglobin in the red blood cells binds to the oxygen and leaves all the other gases alone. It moves on from the lungs and delivers the oxygen to the rest of the body. It's the hemoglobin that does the work.
Hemoglobin is the component of blood that contains iron and is responsible for binding with oxygen.
The component of blood that contains hemoglobin and is responsible for carrying oxygen is red blood cells, also known as erythrocytes. Hemoglobin is a protein within these cells that binds to oxygen in the lungs and transports it to tissues throughout the body. This process is crucial for maintaining cellular respiration and overall metabolic function.
Iron is the element responsible for transporting oxygen to the blood. It is a vital component of hemoglobin, the protein in red blood cells that binds to oxygen and carries it throughout the body.
Red blood cells, which are a component of blood, carry oxygen throughout the body. They contain hemoglobin, a protein that binds to oxygen and transports it to various tissues and organs.
Red blood cells are a major cell component of blood responsible for carrying oxygen. They contain hemoglobin, a protein that binds to oxygen in the lungs and transports it to tissues throughout the body.
Iron is the mineral needed for the transport of oxygen in the blood. It is a crucial component of hemoglobin, the protein in red blood cells that binds to oxygen and carries it from the lungs to the rest of the body.
Red blood cells are responsible for oxygen exchange
oxygen binds with hemoglobin in the lungs and forms oxyhemoglobin.
Hemoglobin is the protein in the blood that binds to oxygen. It is mainly found in red blood cells and is responsible for transporting oxygen from the lungs to the tissues in the body.
Hemoglobin is the component in red blood cells that carries oxygen molecules to the somatic cells in the body. Hemoglobin binds to oxygen in the lungs and releases it in tissues where it is needed for cellular respiration.
Hemoglobin, a protein found in red blood cells, helps to absorb and transport oxygen throughout the body. Hemoglobin binds to oxygen in the lungs and releases it to tissues that need oxygen for energy production.
Hemoglobin is red in color because it contains iron, which binds to oxygen and gives blood its red hue.
