Protein synthesis in a mature RBC occurs primarily __________. nowhere; mature red blood cells cannot synthesize proteins in mitochondria in the nucleus in ribosomes

nowhere; mature red blood cells cannot synthesize proteins

The primary function of a mature red blood cell is which of the following? Transport of respiratory gases Delivery of enzymes to target tissues Defense against toxins and pathogens All of the listed responses are correct.

transport of respiratory gases

Which blood type can safely be transfused into a person with type O blood? Type O Type A Type B Type AB

type O

What type of blood is considered to be the "universal donor"? Type O negative Type AB positive Type A negative Type B negative

type O negative

Where are red blood cells produced in an adult? Red bone marrow Yellow bone marrow Liver Lungs

red bone marrow

Red blood cells have a limited lifespan and then are phagocytized by macrophages in the liver, spleen and red bone marrow. What happens to the iron in the heme group of RBCs? The iron will be either stored in the liver or transported back to the red bone marrow to be incorporated into new hemoglobin. The iron is converted into biliverdin. The iron becomes part of bile and is excreted into the digestive tract. The iron is excreted by the kidneys as urobilins in the urine.
