Always red with and without oxygen because when you go to the doctor to get a shot it has a tube and when the doctor takes the shot the blood is very dark red
The color of blood changes from a brighter red to a darker red. Many people will say that the color in veins is "blue" but this is not accurate.
something to do with hemoglobin. the colour is different depending on whether it is or isn't bonded with oxygen
Hemoglobin is the molecule in the red blood cell that carries oxygen. Iron is one of hemoglobin's chief components.
This chemical is hemoglobin.
ways of transporting oxygen (presumably in the human body you are referring to) it is carried in the blood as part of the circulatory system-it is picked up from the lungs through alveoli -majorly carried in the blood as oxyhaemoglobin (oxygen combined with haemoglobin in red blood cells) -some can be dissolved in the blood plasma
Red blood cells contain a protein called hemoglobin. Hemoglobin is able to bind to oxygen molecules. Therefore, the presence of hemoglobin the red blood cells makes them capable of carrying oxygen.
Hemoglobin
Blood is not always red. The colour is dependant on it's exposure to oxygen. If there is oxygen in the blood it has a red colour. That is why whenever you bleed your blood is red, because it reacts with the oxygen in the air. When there is no oxygen in your blood though, your blood has a blue colour.
Oxygen in the blood is transported by hemoglobin.
The red blood cells don't loose hemoglobin. Hemoglobin is the protein the oxygen binds to. So I think a better question is " What is the colour of RBC's without oxygen?" And the answer in a dark red.
Iron Hemoglobin which contains iron, so that it con bind oxygen. Although Iron is an element. Hemoglobin is a molecule.
The protein hemoglobin, which carries oxygen in the blood, changes shape when it binds oxygen. When it changes shape, it absorbs different wavelengths of light, making it change color. When blood is exposed to air, much more of the hemoglobin absorbs oxygen than had in the vein the blood came from (in the veins, the hemoglobin has already given up most of its oxygen to the body). Therefore, the blood turns red.Source(s):http://www.newton.dep.anl.gov/askasci/bi…

hemoglobin
Blood is an oxygen transport mechanism (among its other functions) and this is done by means of a chemical called hemoglobin, which, when it is carrying oxygen, has an intense red color.
Hemoglobin carries oxygen to the body's tissues. It is found in erythrocytes.
The blood color of a tiger is red. Like all mammals, tigers have red blood. The color of blood is determined by the presence of hemoglobin, which is a protein that carries oxygen. Hemoglobin is red because it contains iron.
The oxygen-rich hemoglobin.The pigment that makes blood red is known as haemoglobin. it helps blood to carry oxygen.
